Type for use in template object to compare double values

- by DaClown

I got this n-dimensional point object: template <class T, unsigned int dimension> class Obj { protected: T coords[dimension]; static const unsigned int size = dimension; public: Obj() { }; Obj(T def) { for (unsigned int i = 0; i < size; ++i) coords[i]=def; }; Obj(const Obj& o) { for (unsigned int i = 0; i < size; ++i) coords[i] = o.coords[i]; } const Obj& operator= (const Obj& rhs) { if (this != &rhs) for (unsigned int i = 0; i < size; ++i) coords[i] = rhs.coords[i]; return *this; } virtual ~Obj() { }; T get (unsigned int id) { if (id >= size) throw std::out_of_range("out of range"); return coords[id]; } void set (unsigned int id, T t) { if (id >= size) throw std::out_of_range("out of range"); coords[id] = t; } }; and a 3D point class which uses Obj as base class: template <class U> class Point3DBase : public Obj<U,3> { typedef U type; public: U &x, &y, &z; public: Point3DBase() : x(Obj<U,3>::coords[0]), y(Obj<U,3>::coords[1]), z(Obj<U,3>::coords[2]) { }; Point3DBase(U def) : Obj<U,3>(def), x(Obj<U,3>::coords[0]), y(Obj<U,3>::coords[1]), z(Obj<U,3>::coords[2]) { }; Point3DBase(U x_, U y_, U z_) : x(Obj<U,3>::coords[0]), y(Obj<U,3>::coords[1]), z(Obj<U,3>::coords[2]) { x = x_; y = y_; z= z_; }; Point3DBase(const Point3DBase& other) : x(Obj<U,3>::coords[0]), y(Obj<U,3>::coords[1]), z(Obj<U,3>::coords[2]) { x = other.x; y = other.y; z = other.z; } // several operators ... }; The operators, basically the ones for comparison, use the simple compare-the-member-object approach like: virtual friend bool operator== (const Point3DBase<U> &lhs, const Point3DBase<U> rhs) { return (lhs.x == rhs.x && lhs.y == rhs.y && lhs.z == rhs.z); } Then it occured to me that for the comparion of double values the simply equality approach is not very useful since double values should be compared with an error margin. What would be the best approach to introduce an error margin into the point? I thought about an epsDouble type as template parameter but I can't figure out how to achieve this.

input field placeholder in jQuery

- by Hristo

I'm trying to create a Login page, not worrying about actually logging in yet, but I'm trying to achieve the effect where there is some faded text inside the input field and when you click on it, the text disappears or if you click away the text reappears. I have this working for my "Username" input field, but the "Password" field is giving me problems because I can't just do $("#password").attr("type","password"). Here's my code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title>  <link rel="stylesheet" type="text/css" href="style.css" />  <script type="text/javascript" src="jQuery.js"></script> <script> // document script $(document).ready(function(){ // login box event handler $('#login').click(function(){ $('.loginBox').animate({ height: '150px' }, '1000' ); $('#username').show(); // add pw placeholder field $('#password').after('<input type="text" id="placeHolder" value="Password" class="placeHolder" />'); $('#password').hide(); }); // username field focus and blur event handlers $('#username').focus(function() { if($(this).hasClass('placeHolder')){ $(this).val(''); $(this).removeClass('placeHolder'); } }); $('#username').blur(function() { if($(this).val() == '') { $(this).val('Username'); $(this).addClass('placeHolder'); } }); // password field focus and blur event handlers $('#placeHolder').focus(function() { $('#placeHolder').hide(); $('#password').show(); $('#password').focus(); }); $('#password').blur(function() { if($('#password').val() == '') { $('#placeHolder').show(); $('#password').hide(); } }); }); </script> </head> <body> <div id="loginBox" class="loginBox"> <a id="login">Proceed to Login</a><br /> <div id="loginForm"> <form> <input type="text" id="username" class="placeHolder" value="Username" /> <input type="password" id="password" class="placeHolder" value="" /> </form> </div> </div> </body> </html> Right now, I can click on the password input box and type in it, but the text is not disappearing and the "type" doesn't get set to "password"... the new input field I create isn't being hidden, it just stays visible, and I'm not sure where the problem is. Any ideas? Thanks, Hristo

Having different database sorting order (default_scope) for two different views

- by Juniper747

In my model (pins.rb), I have two sorting orders: default_scope order: 'pins.featured DESC' #for adding featured posts to the top of a list default_scope order: 'pins.created_at DESC' #for adding the remaining posts beneath the featured posts This sorting order (above) is how I want my 'pins view' (index.html.erb) to look. Which is just a list of ALL user posts. In my 'users view' (show.html.erb) I am using the same model (pins.rb) to list only current_user pins. HOWEVER, I want to sorting order to ignore the "featured" default scope and only use the second scope: default_scope order: 'pins.created_at DESC' How can I accomplish this? I tried doing something like this: default_scope order: 'pins.featured DESC', only: :index default_scope order: 'pins.created_at DESC' But that didn't fly... UPDATE I updated my model to define a scope: scope :featy, order: 'pins.featured DESC' default_scope order: 'pins.created_at DESC' And updated my pins view to: <%= render @pins.featy %> However, now when I open my pins view, I get the error: undefined method `featy' for #<Array:0x00000100ddbc78> UPDATE 2 User.rb class User < ActiveRecord::Base attr_accessible :name, :email, :username, :password, :password_confirmation, :avatar, :password_reset_token, :password_reset_sent_at has_secure_password has_many :pins, dependent: :destroy #destroys user posts when user is destroyed # has_many :featured_pins, order: 'featured DESC', class_name: "Pin", source: :pin has_attached_file :avatar, :styles => { :medium => "300x300#", :thumb => "120x120#" } before_save { |user| user.email = user.email.downcase } before_save { |user| user.username = user.username.downcase } before_save :create_remember_token before_save :capitalize_name validates :name, presence: true, length: { maximum: 50 } VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i VALID_USERNAME_REGEX = /^[A-Za-z0-9]+(?:[_][A-Za-z0-9]+)*$/ validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false } validates :username, presence: true, format: { with: VALID_USERNAME_REGEX }, uniqueness: { case_sensitive: false } validates :password, length: { minimum: 6 }, on: :create #on create, because was causing erros on pw_reset Pin.rb class Pin < ActiveRecord::Base attr_accessible :content, :title, :privacy, :date, :dark, :bright, :fragmented, :hashtag, :emotion, :user_id, :imagesource, :imageowner, :featured belongs_to :user before_save :capitalize_title before_validation :generate_slug validates :content, presence: true, length: { maximum: 8000 } validates :title, presence: true, length: { maximum: 24 } validates :imagesource, presence: { message: "Please search and choose an image" }, length: { maximum: 255 } validates_inclusion_of :privacy, :in => [true, false] validates :slug, uniqueness: true, presence: true, exclusion: {in: %w[signup signin signout home info privacy]} # for sorting featured and newest posts first default_scope order: 'pins.created_at DESC' scope :featured_order, order: 'pins.featured DESC' def to_param slug # or "#{id}-#{name}".parameterize end def generate_slug # makes the url slug address bar freindly self.slug ||= loop do random_token = Digest::MD5.hexdigest(Time.zone.now.to_s + title)[0..9]+"-"+"#{title}".parameterize break random_token unless Pin.where(slug: random_token).exists? end end protected def capitalize_title self.title = title.split.map(&:capitalize).join(' ') end end users_controller.rb class UsersController < ApplicationController before_filter :signed_in_user, only: [:edit, :update, :show] before_filter :correct_user, only: [:edit, :update, :show] before_filter :admin_user, only: :destroy def index if !current_user.admin? redirect_to root_path end end def menu @user = current_user end def show @user = User.find(params[:id]) @pins = @user.pins current_user.touch(:last_log_in) #sets the last log in time if [email protected]? render 'pages/info/' end end def new @user = User.new end pins_controller.rb class PinsController < ApplicationController before_filter :signed_in_user, except: [:show] # GET /pins, GET /pins.json def index #Live Feed @pins = Pin.all @featured_pins = Pin.featured_order respond_to do |format| format.html # index.html.erb format.json { render json: @pins } end end # GET /pins, GET /pins.json def show #single Pin View @pin = Pin.find_by_slug!(params[:id]) require 'uri' #this gets the photo's id from the stored uri @image_id = URI(@pin.imagesource).path.split('/').second if @pin.privacy == true #check for private pins if signed_in? if @pin.user_id == current_user.id respond_to do |format| format.html # show.html.erb format.json { render json: @pin } end else redirect_to home_path, notice: "Prohibited 1" end else redirect_to home_path, notice: "Prohibited 2" end else respond_to do |format| format.html # show.html.erb format.json { render json: @pin } end end end # GET /pins, GET /pins.json def new @pin = current_user.pins.new respond_to do |format| format.html # new.html.erb format.json { render json: @pin } end end # GET /pins/1/edit def edit @pin = current_user.pins.find_by_slug!(params[:id]) end Finally, on my index.html.erb I have: <%= render @featured_pins %>

How to use XSLT to tag specific nodes with unique, sequential, increasing integer ids?

- by ~otakuj462

Hi, I'm trying to use XSLT to transform a document by tagging a group of XML nodes with integer ids, starting at 0, and increasing by one for each node in the group. The XML passed into the stylesheet should be echoed out, but augmented to include this extra information. Just to be clear about what I am talking about, here is how this transformation would be expressed using DOM: states = document.getElementsByTagName("state"); for( i = 0; i < states.length; i++){ states.stateNum = i; } This is very simple with DOM, but I'm having much more trouble doing this with XSLT. The current strategy I've devised has been to start with the identity transformation, then create a global variable which selects and stores all of the nodes that I wish to number. I then create a template that matches that kind of node. The idea, then, is that in the template, I would look up the matched node's position in the global variable nodelist, which would give me a unique number that I could then set as an attribute. The problem with this approach is that the position function can only be used with the context node, so something like the following is illegal: <template match="state"> <variable name="stateId" select="@id"/> <variable name="uniqueStateNum" select="$globalVariable[@id = $stateId]/position()"/> </template> The same is true for the following: <template match="state"> <variable name="stateId" select="@id" <variable name="stateNum" select="position($globalVariable[@id = $stateId])/"/> </template> In order to use position() to look up the position of an element in $globalVariable, the context node must be changed. I have found a solution, but it is highly suboptimal. Basically, in the template, I use for-each to iterate through the global variable. For-each changes the context node, so this allows me to use position() in the way I described. The problem is that this turns what would normally be an O(n) operation into an O(n^2) operation, where n is the length of the nodelist, as this require iterating through the whole list whenever the template is matched. I think that there must be a more elegant solution. Altogether, here is my current (slightly simplified) xslt stylesheet: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:s="http://www.w3.org/2005/07/scxml" xmlns="http://www.w3.org/2005/07/scxml" xmlns:c="http://msdl.cs.mcgill.ca/" version="1.0"> <xsl:output method="xml"/>  <xsl:variable name="states" select="//s:state" />  <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="s:state"> <xsl:variable name="stateId"> <xsl:value-of select="@id"/> </xsl:variable> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:for-each select="$states"> <xsl:if test="@id = $stateId"> <xsl:attribute name="stateNum" namespace="http://msdl.cs.mcgill.ca/"> <xsl:value-of select="position()"/> </xsl:attribute> </xsl:if> </xsl:for-each> <xsl:apply-templates select="node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> I'd appreciate any advice anyone can offer. Thanks.

Sencha Touch 2 - Can't get list to display // or load a store? [UPDATED X2]

- by Jordan

I have been trying to get a list to display for quite a while now. I have tried all sorts of tips from various people without success. Now I am running into a new problem. I have taken the exact code from an example and I can't seem to get it to work either. First of all, here is the code. Station.js Ext.define('Syl.model.Station', { extend: 'Ext.data.Model', config: { fields: [ { name: 'id', type: 'string' }, { name: 'stop', type: 'string' } ] } }); Stations.js Ext.define('Syl.store.Stations', { extend : 'Ext.data.Store', requires: ['Syl.model.Station'], id: 'stations', xtype: 'stations', config : { model : 'Syl.model.Station', //storeId: 'stationsStore', autoLoad : true, //sorters: 'stop', /* proxy: { type: 'ajax', url: 'stations.json' }*/ data: [ { "id": "129", "stop": "NY Station" }, { "id": "13", "stop": "Newark Station" } ] } }); MyService.js Ext.define('Syl.view.MyService', { extend: 'Ext.Panel', xtype: 'stationsformPage', requires: [ 'Syl.store.Stations', 'Ext.form.FieldSet', 'Ext.field.Password', 'Ext.SegmentedButton', 'Ext.List' ], config: { fullscreen: true, layout: 'vbox', //iconCls: 'settings', //title: 'My Service', items: [ { docked: 'top', xtype: 'toolbar', title: 'My Service' }, { [OLDER CODE BEGIN] xtype: 'list', title: 'Stations', //store: 'Stations', store: stationStore, //UPDATED styleHtmlContent: true, itemTpl: '<div><strong>{stop}</strong> {id}</div>' [OLDER CODE END] [UPDATE X2 CODE BEGIN] xtype: 'container', layout: 'fit', flex: 10, items: [{ xtype: 'list', title: 'Stations', width: '100%', height: '100%', store: stationStore, styleHtmlContent: true, itemTpl: '<div><strong>{stop}</strong> {id}</div>' }] [UPDATE X2 CODE END] }, ] } }); app.js (edited down to the basics) var stationStore; //UPDATED Ext.application({ name: 'Syl', views: ['MyService'], store: ['Stations'], model: ['Station'], launch: function() { stationStore = Ext.create('Syl.store.Stations');//UPDATED var mainPanel = Ext.Viewport.add(Ext.create('Syl.view.MyService')); }, }); Okay, now when I run this in the browser, I get this error: "[WARN][Ext.dataview.List#applyStore] The specified Store cannot be found". The app runs but there is no list. I can't understand how this code could work for the people who gave the example and not me. Could it be a difference in the Sencha Touch version? I am using 2.0.1.1. To add to this, I have been having problems in general with lists not displaying. I had originally tried a stripped down list without even having a store. I tried to just set the data property in the list's config. I didn't get this error, but I also didn't get a list to display. That is why I thought I would try someone else's code. I figured if I could at least get a working list up and running, I could manipulate it into doing what I want. Any help would be greatly appreciated. Thanks. [UPDATED] Okay, so I did some more hunting and someone told me I needed to have an instance of my store to load into the list, not the store definition. So I updated the code as you can see and the error went away. The problem is that I still don't get a list. I have no errors at all, but I can't see a list. Am I not loading the data correctly? Or am I not putting the list in the view correctly? [UPDATED X2] Okay, so I learned that the list should be in a container and that I should give it a width and a height. I'm not totally sure on this being correct, but I do now have a list that I can drag up and down. The problem is there is still nothing in it. Anyone have a clue why?

JQuery help, How to Hide all button in JQuery

- by user303518

Hi guys, I'm trying to make a request/reply section in my project. I want to achieve these functionality in that code (that I'm not able to implement; so guys please help me out): 1 When user click on reply button; other reply area(text-area +button) should be hide (means at a time only one reply area should be visible to the user). 2 when user click on reply button text-area will focus and page will slide down (suppose user reply 10 comment focus will automatically set to the 10 number text area and page will slide down to that position accordingly). Here is my so far code guys: //method call on the click of reply link. function linkReply_Clicked(issueId) { Id = issueId; textId = "text_" + issueId + count; btnReply = "btnReply_" + issueId + count; btnCancel = "btnCancel_" + issueId + count; var textareasArray = document.getElementsByTagName("textarea"); var btnArray = document.getElementsByTagName("input"); for (i = 0; i < textareasArray.length; i++) { textareasArray[i].style.display = "none"; btnArray[i].style.display = "none"; } var str = "<table cellpadding='3' cellspacing='0' width='58%'>"; str += "<tr><td valign='top' align='left'>"; str += "<textarea id=" + textId + " rows='5' cols='60'></textarea>"; str += "</td></tr>"; str += "<tr><td valign='top' align='right'>"; str += "<input id=" + btnReply + " type='button' onclick='btnReply_Clicked(Id ,textId)' value='Reply' /> "; str += "<input id=" + btnCancel + " type='button' onclick='btnCancel_Clicked(Id ,textId)' value='Cancel' /> "; str += "</td></tr>"; str += "</table>"; document.getElementById("divOuter_" + issueId).innerHTML = str; $("#" + textId + "").focus(); } // submit user reply and try to hide that reply area. function btnReply_Clicked(issueId, textID) { var comment = document.getElementById(textID).value; if (comment != '') { $.getJSON("/Issue/SaveComment", { IssueId: issueId, Comment: comment }, null); $("#text_" + issueId + count).hide(); $("#btnReply_" + issueId + count).hide(); $("#btnCancel_" + issueId + count).hide(); document.getElementById(textID).value = ''; count = count + 1; } } // cancel user reply and try to hide that reply area. function btnCancel_Clicked(issueId, textId) { $("#text_" + issueId + count).hide(); $("#btnReply_" + issueId + count).hide(); $("#btnCancel_" + issueId + count).hide(); document.getElementById(textId).value = ''; count = count + 1; }

Hi, I have a page which basically allows an admin user to create manager user types (basically a register function. So when the values are submitted, they are stored into the DB, very very basic stuff. However, I have a hidden variable type..reasons are I have 3 different user levels and I have declared they identification as an integer (e.g. 7 = manager, 8 =user etc.) Can someone help me out with how to correctly pass this hidden value so it stores in the database... Here is my form: <form id="userreg" name="userreg" method="post" action="adminadduser-process.php"> <label>Full Name:</label> <input name="fullname" size="40" id="fullname" value="<?php if (isset($_POST['fullname'])); ?>"/> <br /> <label>Username:</label> <input name="username" size="40" id="username" value="<?php if (isset($_POST['username'])); ?>"/> <br /> <label>Password:</label> <input name="password" size="40" id="password" value="<?php if (isset($_POST['password'])); ?>"/> <br /> <label>Email Address:</label> <input name="emailaddress" size="40" id="emailaddress" value="<?php if (isset($_POST['emailaddress'])); ?>"/> <br /> <input name="userlevel" type="hidden" size="1" id="userlevel" value="<?php $_POST[5]; ?>" /> <br /> <input value="Add User" class="addbtn" type="submit" /> </form></div> Next, here is the script that runs the query: <?php require_once "config.php"; $fullname = $_POST['fullname']; $username = $_POST['username']; $password = $_POST['password']; $emailaddress = $_POST['emailaddress']; $userlevel = $_POST[5]; $sql = "INSERT INTO users_tb VALUES('".$user_id."','".$fullname."','".$username."',MD5('".$password."'),'".$emailaddress."','".$userlevel."')"; $result = mysql_query($sql, $connection) or die("MySQL Error: ".mysql_error()); header("Location: adminhome.php"); exit(); ?> I'm basically trying to pass the hidden typem with a constant value of '5' just for this form, as it will not be changed...also while im here, for some reason, the 'fullname' is not stored in the DB either!!?? WTH?? all other fields are processed fine. Any help is much appreciated! Thank you.

conditional selects with jQuery and the Validation plugin

- by dbonomo

Hi, I've got a form that I am validating with the jQuery validation plugin. I would like to add a conditional select box (a selection box that is populated/shown depending on the selection of another) and have it validate as well. Here is what I have so far: $(document).ready(function(){ $("#customer_information").validate({ //disable the submit button after it is clicked to prevent multiple submissions submitHandler: function(form){ if(!this.wasSent){ this.wasSent = true; $(':submit', form).val('Please wait...') .attr('disabled', 'disabled') .addClass('disabled'); form.submit(); } else { return false; } }, //Customizes error placement errorPlacement: function(error, element) { error.insertAfter(element) error.wrap("<div class=\"form_error\">") } }); $(".courses").hide(); $("#course_select").change(function() { switch($(this).val()){ case "Certificates": $(".courses").hide().parent().find("#Certificates").show(); $(".filler").hide(); break; case "Associates": $(".courses").hide().parent().find("#Associates").show(); $(".filler").hide(); break; case "": $(".filler").show(); $(".courses").hide(); } }); }); And the HTML: <select id="course_select"> <option value="">Please Select</option> <option value="Certificates">Certificates</option> <option value="Associates">Associates</option> </select> <div id="Form0" class="filler"><select name="filler_select"><option value="">Please Select Course Type</option></select></div> <div id="Associates" class="courses"> <select name="lead_source_id" id="Requested Program" class="required"> <option value="">Please Select</option> <option value="01">Health Information Technology</option> <option value="02">Human Resources </option> <option value="03">Marketing </option> </select> </div> <div id="Certificates" class="courses"> <select name="lead_source_id" id="Requested Program" class="required"> <option value="">Please Select</option> <option value="04">Accounting Services</option> <option value="05">Bookkeeping</option> <option value="06">Child Day Care</option> </select> </div> So far, the select is working for me, but validation thinks that the field is empty even when a value is selected. It looks like there are a ton of ways to do conditional selects in jQuery. This was the best way I managed to work out (I'm new to jQuery), but I'd love to hear what you folks feel is the "best" way, especially if it works well with the validation plugin. Thanks!

Jquery mobile ajax request not working after 4-5 request is made in Android

- by Coder_sLaY

I am developing an application using jQuery mobile 1.1.0 RC1 and phonegap 1.5.0 I have a single HTML page which contains all the pages in it as a div(through data-role="page") here is my code <!DOCTYPE HTML> <html> <head> <title>Index Page</title>  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1">  <script type="text/javascript" charset="utf-8" src="cordova/cordova-1.5.0.js"></script>  <script type="text/javascript" src="jquery/jquery-1.7.1.min.js"></script> <link rel="stylesheet" href="jquerymobile/jquery.mobile-1.1.0-rc.1.min.css" /> <script type="text/javascript" src="jquery/jquery.validate.min.js"></script> <script type="text/javascript" src="jquerymobile/jquery.mobile-1.1.0-rc.1.min.js"></script> <link rel="stylesheet" href="css/colors.css"> <script type="text/javascript"> function page1(){ $.mobile.changePage("#page2", { transition : "slide" }); } function page2(){ $.mobile.changePage("#page1", { transition : "slide" }); } $("#page1").live("pageshow", function(e) { $.ajax({ type : 'GET', cache : false, url : "http://192.168.1.198:9051/something.xml" + "?time=" + Date.now(), data : { key : "value" }, dataType : "xml", success : function(xml) { console.log("Success Page1"); }, error : function(xhr) { } }); }); $("#page2").live("pageshow", function(e) { $.ajax({ type : 'GET', cache : false, url : "http://192.168.1.198:9051/something.xml" + "?time=" + Date.now(), data : { key : "value" }, dataType : "xml", success : function(xml) { console.log("Success Page2"); }, error : function(xhr) { } }); }); </script> <body> <div data-role="page" id="page1"> <div data-role="header">Page 1</div> <div data-role="content"> <input type="text" name="page1GetTime" id="page1GetTime" value="" /><a href="#" data-role="button" onclick="page1()" id="gotopage2"> Go to Page 2 </a> </div> </div> <div data-role="page" id="page2"> <div data-role="header">Page 2</div> <div data-role="content"> <input type="text" name="page2GetTime" id="page2GetTime" value="" /><a href="#" data-role="button" onclick="page2()" id="gotopage1">Go to Page 1</a> </div> </div> </body> Now when i click to "Go to page2" then page2 will be shown along with one ajax request .. If i keep on moving from one page to another then a ajax request is made.. This request stops responding after 4 to 5 request... Why is it happening?

jQuery - Stucked Animation

- by v1n_vampire

I'm kind of tired with Javascript long script for animation and decide to try jQuery, but it seems I'm stuck even at the simplest code. CSS: #menu {float: right; font: italic 16px/16px Verdana, Geneva, sans-serif;} ul#nav {list-style: none;} ul#nav li {float: left; padding-right: 10px;} ul#nav li a {color: white;} ul#subnav {float: right; list-style: none; padding: 0; display: none;} ul#subnav li {float: left; padding: 10px 5px; white-space: nowrap;} ul#subnav li a {color: white;} Script: $(document).ready(function() { $('.nav').hover(function() { $(this).find('#subnav').stop().animate({width:'toggle'},350); }); }); HTML: <div id="menu"> <ul id="nav"> <li class="nav"> <a href="#"><img src="images/icon-home.png" width="36" height="36"/></a> <ul id="subnav"> <li><a href="#">Home</a></li> </ul> </li> <li class="nav"> <a href="#"><img src="images/icon-signin.png" width="36" height="36"/></a> <ul id="subnav"> <li><a href="#">Sign In</a></li> </ul> </li> <li class="nav"> <a href="#"><img src="images/icon-register.png" width="36" height="36"/></a> <ul id="subnav"> <li><a href="#">Create Account</a></li> </ul> </li> <li class="nav" style="padding-right: 0;"> <a href="#"><img src="images/icon-mail.png" width="36" height="36"/></a> <ul id="subnav"> <li style="padding-right: 0;"><a href="#">Contact Us</a></li> </ul> </li> </ul> </div> Here's the sample page: http://v1n-vampire.com/dev/jq-animation-stuck If you continue to hover on the nav from left to right then back to left, eventually the animation will stuck. How to solve this? Thank you in advance.

How can I clear content without getting the dreaded "stop running this script?" dialog?

- by Cheeso

I have a div, that holds a div. like this: <div id='reportHolder' class='column'> <div id='report'> </div> </div> Within the inner div, I add a bunch (7-12) of pairs of a and div elements, like this: <h4><a>Heading1</a></h4> <div> ...content here....</div> The total size of the content, is maybe 200k. Each div just contains a fragment of HTML. Within it, there are numerous <span> elements, containing other html elements, and they nest, to maybe 5-8 levels deep. Nothing really extraordinary, I don't think. After I add all the content, I then create an accordion. like this: $('#report').accordion({collapsible:true, active:false}); This all works fine. The problem is, when I try to clear or remove the report div, it takes a looooooong time, and I get 3 or 4 popups asking "Do you want to stop running this script?" I have tried several ways: option 1: $('#report').accordion('destroy'); $('#report').remove(); $("#reportHolder").html("<div id='report'> </div>"); option 2: $('#report').accordion('destroy'); $('#report').html(''); $("#reportHolder").html("<div id='report'> </div>"); option 3: $('#report').accordion('destroy'); $("#reportHolder").html("<div id='report'> </div>"); after getting a suggestion in the comment, I also tried: option 4: $('#report').accordion('destroy'); $('#report').empty(); $("#reportHolder").html("<div id='report'> </div>"); No matter what, it hangs for a long while. The call to accordion('destroy') seems to not be the source of the delay. It's the erasure of the html content within the report div. This is jQuery 1.3.2. EDIT - fixed code typo. ps: this happens on FF3.5 as well as IE8 . Questions: What is taking so long? How can I remove content more quickly? Addendum I broke into the debugger in FF, during "option 4", and the stacktrace I see is: data() trigger() triggerHandler() add() each() each() add() empty() each() each() (?)() // <<-- this is the call to empty() ResetUi() // <<-- my code onclick I don't understand why add() is in the stack. I am removing content, not adding it. I'm afraid that in the context of the remove (all), jQuery does something naive. Like it grabs the html content, does the text replace to remove one html element, then calls .add() to put back what remains. Is there a way to tell jQuery to NOT propagate events when removing HTML content from the dom?

Javascript auto calculating

- by Josh

I have page that automatically calculates a Total by entering digits into the fields or pressing the Plus or Minus buttons. I need to add a second input after the Total that automatically divides the total by 25. Here is the working code with no JavaScript value for the division part of the code: <html> <head> <script language="text/javascript"> function Calc(className){ var elements = document.getElementsByClassName(className); var total = 0; for(var i = 0; i < elements.length; ++i){ total += parseFloat(elements[i].value); } document.form0.total.value = total; } function addone(field) { field.value = Number(field.value) + 1; Calc('add'); } function subtractone(field) { field.value = Number(field.value) - 1; Calc('add'); } </script> </head> <body> <form name="form0" id="form0"> 1: <input type="text" name="box1" id="box1" class="add" value="0" onKeyUp="Calc('add')" onChange="updatesum()" onClick="this.focus();this.select();" /> <input type="button" value=" + " onclick="addone(box1);"> <input type="button" value=" - " onclick="subtractone(box1);"> <br /> 2: <input type="text" name="box2" id="box2" class="add" value="0" onKeyUp="Calc('add')" onClick="this.focus();this.select();" /> <input type="button" value=" + " onclick="addone(box2);"> <input type="button" value=" - " onclick="subtractone(box2);"> <br /> 3: <input type="text" name="box3" id="box3" class="add" value="0" onKeyUp="Calc('add')" onClick="this.focus();this.select();" /> <input type="button" value=" + " onclick="addone(box3);"> <input type="button" value=" - " onclick="subtractone(box3);"> <br /> <br /> Total: <input readonly style="border:0px; font-size:14; color:red;" id="total" name="total"> <br /> Totaly Divided by 25: <input readonly style="border:0px; font-size:14; color:red;" id="divided" name="divided"> </form> </body></html> I have the right details but the formulas I am trying completely break other aspects of the code. I cant figure out how to make the auto adding and auto dividing work at the same time

Encoding GBK2312 Condundrum

- by user792271

I am an amateur coder and I have a small problem. My goal is to have one text input with two buttons. The first button uses a bit of Javascript called SundayMorning to translate the text (to Chinese) The second button submits the text to a URL. The URl requires that Chinese text be encoded it in GBK2312 character set. I have duct taped together various found code to the result I have now. Due to the finicky behavior of the SundayMorning Javascript, my solution is to have two input boxes, the second of which I will hide. Right now, this doesn't work: I am unable to encode the Chinese in GBK2312, no matter what I try. BONUS CONUNDRUM: The second box copies my input letter by letter as I type, but does not copy the Chinese translation that the Javascript returns. Sorry for my janky amateur code. I defer to those more clever, if you have any kind suggestions. <head> <meta http-equiv="Content-Type" content="text/html; charset=GB2312" /> <script type='text/javascript' Src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js'> </script> ///THIS JS TRANSLATES THE TEXT INLINE <script type="text/javascript" src="jquery.sundaymorning.js"> </script> <script type="text/javascript"> $(function() { $('#example3').sundayMorningReset(); $('#example3 input[type=image]').click(function(evt) { $.sundayMorning( $('#example3 input[type=text]').val(),{source:'en', destination:'ZH', menuLeft:evt.pageX, menuTop:evt.pageY},function(response) {$('#example3 input[type=text]').val(response.translation);});});}); </script> /// ///THIS PUTS THE CONTENT OF THE TRANSLATION BOX INTO THE SUBMISSION BOX <script type="text/javascript"> $(document).ready(function(){ var $url = $("#url"); $("#track").keyup(function() { $url.val(this.value);}); $("#track").blur(function() { $url.val(this.value);});}); </script> ///THIS PUTS THE CONTENT OF THE SUBMISSION INSIDE A URL <SCRIPT type="text/javascript"> function goToPage(url) { var initial = "http://example.com/"; var extension = ".html"; document.something.action=initial+url+extension; } </SCRIPT> </head> <body> <div id="featured"> <div id="example3"> <input type="text" name="track" id="track" value="" class="box"onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('mama').click();}};"/> <input type="image" src="http://taobaofieldguide.com/images/orange-translate-button.png" id="searchsubmit" value="Translate" class="btn" /> </div> <FORM name="something" method="post" onsubmit="goToPage(this.url.value);"> <input type="text" id="url";> <INPUT type="submit" id="mama" value="GO" > </FORM> </div> </body>

How can I make three partials into just one in rails where the :collection is the same?

- by Angela

I have three partials that I'd like to consolidate into one. They share the same collection, but each gets passed its own :local variable. Those variables are used for specific Models, so as a result, I have three different calls to the partial and three different partials. Here's the repetitive code: <% for email in campaign.emails %> <h4><%= link_to email.title, email %> <%= email.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%>   <%= render :partial => "contact_email", :collection => @contacts, :locals => {:email => email} %> <% end %> Calls in this Campaign: <% for call in campaign.calls %> <h4><%= link_to call.title, call %> <%= call.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%>   <%= render :partial => "contact_call", :collection => @contacts, :locals => {:call => call} %> <% end %> Letters in this Campaign: <% for letter in campaign.letters %> <h4><%= link_to letter.title, letter %> <%= letter.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%>   <%= render :partial => "contact_letter", :collection => @contacts, :locals => {:letter => letter} %> <% end %> An example of one of the partials is as follows: < div id="contact_email_partial"> <% if from_today(contact_email, email.days) < 0 %> <% if show_status(contact_email, email) == 'no status'%> <p> <%= full_name(contact_email) %> <% unless contact_email.statuses.empty?%> (<%= contact_email.statuses.find(:last).status%>) <% end %> is <%= from_today(contact_email,email.days).abs%> days overdue: <%= do_event(contact_email, email) %> <%= link_to_remote "Skip Email Remote", :url => skip_contact_email_url(contact_email,email), :update => "update-area-#{contact_email.id}-#{email.id}" %> <span id='update-area-<%="#{contact_email.id}-#{email.id}"%>'> </span> <% end %> <% end %> </div>

Android - How do I load a contact Photo?

- by PaulH

I'm having trouble loading a photo for a contact in Android. I've googled for an answer, but so far have come up empty. Does anyone have an example of querying for a Contact, then loading the Photo? So, given a contactUri which comes from an Activity result called using startActivityForResult(new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI),PICK_CONTACT_REQUEST) is: content://com.android.contacts/data/1557 The loadContact(..) works fine. However when I call the getPhoto(...) method, I get a null value for the photo InputStream. It is also confusing because the URI values are different. The contactPhotoUri evaluates to: content://com.android.contacts/contacts/1557 See the comments inline in the code below. class ContactAccessor { /** * Retrieves the contact information. */ public ContactInfo loadContact(ContentResolver contentResolver, Uri contactUri) { //contactUri --> content://com.android.contacts/data/1557 ContactInfo contactInfo = new ContactInfo(); // Load the display name for the specified person Cursor cursor = contentResolver.query(contactUri, new String[]{Contacts._ID, Contacts.DISPLAY_NAME, Phone.NUMBER, Contacts.PHOTO_ID}, null, null, null); try { if (cursor.moveToFirst()) { contactInfo.setId(cursor.getLong(0)); contactInfo.setDisplayName(cursor.getString(1)); contactInfo.setPhoneNumber(cursor.getString(2)); } } finally { cursor.close(); } return contactInfo; // <-- returns info for contact } public Bitmap getPhoto(ContentResolver contentResolver, Long contactId) { Uri contactPhotoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId); // contactPhotoUri --> content://com.android.contacts/contacts/1557 InputStream photoDataStream = Contacts.openContactPhotoInputStream(contentResolver,contactPhotoUri); // <-- always null Bitmap photo = BitmapFactory.decodeStream(photoDataStream); return photo; } public class ContactInfo { private long id; private String displayName; private String phoneNumber; private Uri photoUri; public void setDisplayName(String displayName) { this.displayName = displayName; } public String getDisplayName() { return displayName; } public void setPhoneNumber(String phoneNumber) { this.phoneNumber = phoneNumber; } public String getPhoneNumber() { return phoneNumber; } public Uri getPhotoUri() { return this.photoUri; } public void setPhotoUri(Uri photoUri) { this.photoUri = photoUri; } public long getId() { return this.id; } public void setId(long id) { this.id = id; } } } Clearly, I'm doing something wrong here, but I can't seem to figure out what the problem is. Thanks.

jquery ui draggable elements not 'draggable' outside of scrolling div

- by Stu

hello all, i am super stumped. i have many elements (floating href tags) in a div with a set height/width, with scroll set to "overflow: auto" in the css. this is the structure of the divs: <div id="tagFun_div_main"> <div id="tf_div_tagsReturn">  </div> <div id=" tf_div_tagsDrop"> <div id="tf_dropBox"></div> </div></div> the parent div's, 'tf_div_tagsReturn' and 'tf_div_tagsDrop' will ultimately float next to each other. here is the jquery which is run after all of the 'draggable' elements have been created with class name 'tag_cell', : $(function() { $(".tag_cell").draggable({ revert: 'invalid', scroll: false, containment: '#tagFun_div_main' }); $("#tf_dropBox").droppable({ accept: '.tag_cell', hoverClass: 'tf_dropBox_hover', activeClass: 'tf_dropBox_active', drop: function(event, ui) { GLOBAL_ary_tf_tags.push(ui.draggable.html()); tagFun_reload(); } }); }); as i stated above, the draggable elements are draggable within div 'tf_div_tagsReturn', but they do not visually drag outside of that parent div. worthy to note, if i am dragging one of the draggable elements, and move the mouse over the droppable div, with id 'tf_dropBox', then the hoverclass is fired, i just can't see the draggable element any more. thank you very much for any advice on helping me find a solution. this is my first run at using jquery, so hopefully i am just missing something super obvious. i've been reading the documentation and searching forums thus far to no prevail :( thank you for your time. UPDATE: many thanks to Jabes88 for providing the solution which allowed me to achieve the functionality i was looking for, here is what my jquery ended up looking like, feel free to critique it, as i am new to jquery. $(function() { $(".tag_cell").draggable({ revert: 'invalid', scroll: false, containment: '#tagFun_div_main', helper: 'clone', start : function() { this.style.display="none"; }, stop: function() { this.style.display=""; } }); $(".tf_dropBox").droppable({ accept: '.tag_cell', hoverClass: 'tf_dropBox_hover', activeClass: 'tf_dropBox_active', drop: function(event, ui) { GLOBAL_ary_tf_tags.push(ui.draggable.html()); tagFun_reload(); } }); });

C# creating a queue to handle jobs triggered by FileSystemWatcher

- by John S

I have built a small tray app that will watch a folder and when a new file is added it runs a job. The job is to watch for video files and convert them to .mp4 using handBrakeCli. I have all this logic worked out. The problem I run into is that if there is more than one file I want it to queue the job til the prior one is complete. I am fairly new to c# and I am not sure of the best way to handle this. one idea is to create a queue somehow, a file to store the commands in order maybe, then execute the next one after the process is complete. We are dealing with large movie files here so it can take a while. I am doing this on a quad core with 8gb of RAM and it seems to generally take about 30mins to complete a full length movie. here is the code I have so far. there are some bits in here that are for future functionality so it refers to some classes that you wont see but it doesnt matter as they arent used here. any suggestions are welcome. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; using System.Diagnostics; using System.Threading; namespace movie_converter { public partial class Form1 : Form { public Form1() { InitializeComponent(); } string hbCli; string cmd; string file; string strfilter = "*.*"; string[] filter = new string[3] { ".mkv", ".avi", ".wmv" }; //static list of types List<string> Ext = new List<string>(); //list of extensions to watch (dynamic) NotifyIcon notifyIcon = new System.Windows.Forms.NotifyIcon(); private void SetUpTrayIcon() { notifyIcon.BalloonTipText = "Movie Converter is running minimized."; notifyIcon.BalloonTipTitle = "I'm still here"; notifyIcon.Text = "John's movie converter"; notifyIcon.Icon = new Icon(@"C:\\Users\\John\\Pictures\\appicon.ico"); notifyIcon.Click += new EventHandler(notifyIcon_Click); if (notifyIcon != null) { notifyIcon.Visible = true; notifyIcon.ShowBalloonTip(2000); } } private void Form_Resize(object sender, EventArgs e) { if (WindowState == FormWindowState.Minimized) { this.Hide(); SetUpTrayIcon(); } } private void notifyIcon_Click(object sender, EventArgs e) { this.Show(); this.WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } public void Watcher() { FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = textBox1.Text + "\\"; //path to watch watcher.Filter = strfilter; //what types to look for set to * and i will filter later as it cant accept an array watcher.NotifyFilter = NotifyFilters.FileName | NotifyFilters.DirectoryName; //properties to look at watcher.IncludeSubdirectories = true; //scan subdirs watcher.Created += new FileSystemEventHandler(OnChanged); //TODO: make this only run if the files are of a certain type watcher.EnableRaisingEvents = true; // start the watcher } static bool IsFileLocked(FileInfo file) { FileStream stream = null; try { stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None); } catch (IOException) { //the file is unavailable because it is: //still being written to //or being processed by another thread //or does not exist (has already been processed) return true; } finally { if (stream != null) stream.Close(); } //file is not locked return false; } // Define the event handlers. private void OnChanged(object source, FileSystemEventArgs e) { string sFile = e.FullPath; //check that file is available FileInfo fileInfo = new FileInfo(sFile); while (IsFileLocked(fileInfo)) { Thread.Sleep(500); } if (System.Diagnostics.Process.GetProcessesByName("HandBrakeCLI").Length != 0) { Thread.Sleep(500); } else { //hbOptions hbCl = new hbOptions(); //hbCli = hbCl.HbCliOptions(); if (textBox3.Text != "") { hbCli = textBox3.Text.ToString(); } else { hbCli = "-e x264 -q 20 -B 160"; } string t = e.Name; string s = t.Substring(0, t.Length - 4); //TODO: fix this its not reliable file = e.FullPath; string opath = textBox1.Text.ToString(); cmd = "-i \"" + file + "\" -o \"" + opath + "\\" + s + ".mp4\" " + hbCli; try { for (int i = 0; i < Ext.Count(); i++) { if (e.Name.Contains(Ext[i])) { Process hb = new Process(); hb.StartInfo.FileName = "D:\\Apps\\Handbrake\\Install\\Handbrake\\HandBrakeCLI.exe"; hb.StartInfo.Arguments = cmd; notifyIcon.BalloonTipTitle = "Now Converting"; notifyIcon.BalloonTipText = file; notifyIcon.ShowBalloonTip(2000); hb.Start(); } } } catch (Exception ex) { MessageBox.Show(ex.Message); } } } private void button1_Click(object sender, EventArgs e) //ok button { //add each array item to the list for (int i = 0; i < filter.Count(); i++) { Ext.Add(filter[i]); } if (textBox1.Text != "" && textBox1.Text.Length > 2) { Watcher(); //call watcher to run } this.WindowState = FormWindowState.Minimized; } private void button2_Click(object sender, EventArgs e) //browse button { //broswe button DialogResult result = folderBrowserDialog1.ShowDialog(); if (result == DialogResult.OK) { textBox1.Text = folderBrowserDialog1.SelectedPath; } } private void button3_Click(object sender, EventArgs e) //commands button { Process np = new Process(); np.StartInfo.FileName = "notepad.exe"; np.StartInfo.Arguments = "hbCLI.txt"; np.Start(); } private void button4_Click(object sender, EventArgs e) //options button { hbOptions options = new hbOptions(); options.ShowDialog(); } private void button5_Click(object sender, EventArgs e) //exit button { this.Close(); } private void Form1_Load(object sender, EventArgs e) { this.Resize += Form_Resize; } } }

ActionLink Problem with Client Template Telerik MVC grid

- by Tassadaque

Hi, i m using Telerik grid to present memos received by user below is the code <%Html.Telerik().Grid<UserManagement.Models.SentMemos>() .Name("ReceivedMemos") .Sortable(sorting => sorting .OrderBy(sortOrder => sortOrder.Add(o => o.MemoDate).Descending())) .DataBinding(dataBinding => dataBinding //Ajax binding .Ajax() //The action method which will return JSON .Select("_AjaxBindingReceivedMemos", "OA" ) ). Columns(colums => { colums.Bound(o => o.MemoID).ClientTemplate(Html.ActionLink("Reply", "ReplyMemo", "OA", new { MemoID = "<#=MemoID#>"}, null).ToString()).Title("Reply").Filterable(false).Sortable(false); colums.Bound(o => o.MemoID).ClientTemplate(Html.ActionLink("Acknowledge", "PreviewMemo", "OA", new { id = "<#=MemoID#>"}, null).ToString()).Title("Acknowledge").Filterable(false).Sortable(false); colums.Bound(o => o.Subject).ClientTemplate(Html.ActionLink("<%#=Subject#>", "PreviewMemo", "OA", new { id = "<#=MemoID#>" }, null).ToString()).Title("Subject"); //colums.Bound(o => Html.ActionLink(o.Subject,"PreviewMemo","OA",new{id=o.MemoID},null).ToString()).Title("Subject"); colums.Bound(o => o.FromEmployeeName); colums.Bound(o => o.MemoDate); }) .Sortable() .Filterable() .RowAction((row) => { row.HtmlAttributes.Add("style", "background:#321211;"); }) .Pageable(pager=>pager.PageSize(6)) .PrefixUrlParameters(false) //.ClientEvents(events => events.OnRowDataBound("onRowDataBound")) .Render(); %> where i m binding third column (Subject) my intention is to make an ActionLink where subject is the display text and i want a dynamic ID coming from <#=MemoID#. memo id is working fine and gives me a link with dynamic Memo IDs. the problem is with the subject i.e ("<#=Subject#") is rendered as it is on the screen without mapping to the actual subject of the memo. i have also tried ("<%#=Subject%") but to no gain. any help is highly appriciated regards

DSOFramer.ocx Hosting word documents in 64 bit Windows Forms

- by Santhosh

It looks like the DSOFramer.ocx component is not available for download anymore from MSDN as described here. Also the DSOFramer component is a 32 bit component. Given this, i have 2 questions: Is there any other alternative for hosting a word document in a Windows Form apart from using the DSOFramer.ocx component? If i move to Windows 64 bit operating system, and run the windows form as a native 64 bit process, then how do I host the word document in a 64 bit process?
