  • Load Globalize cultures with Node.js?

    - by Xeon06
    I'm using jQuery Globalize with Node.js. They have a package.json file so I can simply use it as a module and require it. However, it doesn't load all cultures by default. I was wondering what the proper way to load a culture would be? I could go and do something like require('./node_modules/globalize/lib/cultures/globalize.culture.es-US.js') and load the file directly, but that doesn't seem too elegant. Is there a "proper" way to do this?

  • jQuery expanding menu

    - by Milen
    Hi everybody, i have this html code: <ul id="nav"> <li>Heading 1 <ul> <li>Sub page A</li> <li>Sub page B</li> <li>Sub page C</li> </ul> </li> <li>Heading 2 <ul> <li>Sub page D</li> <li>Sub page E</li> <li>Sub page F</li> </ul> </li> </ul> With this JS code: $(function(){ $('#nav>li>ul').hide(); $('#nav>li').mouseover(function(){ if ($('#nav ul:animated').size() == 0) { $heading = $(this); $expandedSiblings = $heading.siblings().find('ul:visible'); if ($expandedSiblings.size() > 0) { $expandedSiblings.slideUp(500, function(){ $heading.find('ul').slideDown(500); }); } else { $heading.find('ul').slideDown(1000); } } }); }) For now the code works this way: When click on Heading 1, menu is expanded. When click on Heading 2, heading2 submenu menu is expanded and heading 1 submenu is closed. I need to rework it to this: Submenus must be closed automatically on mouseout. Can somebody help me? Thanks in advance!

  • What is happening in Crockford's object creation technique?

    - by Chris Noe
    There are only 3 lines of code, and yet I'm having trouble fully grasping this: Object.create = function (o) { function F() {} F.prototype = o; return new F(); }; newObject = Object.create(oldObject); (from Prototypal Inheritance) 1) Object.create() starts out by creating an empty function called F. I'm thinking that a function is a kind of object. Where is this F object being stored? Globally I guess. 2) Next our oldObject, passed in as o, becomes the prototype of function F. Function (i.e., object) F now "inherits" from our oldObject, in the sense that name resolution will route through it. Good, but I'm curious what the default prototype is for an object, Object? Is that also true for a function-object? 3) Finally, F is instantiated and returned, becoming our newObject. Is the "new" operation strictly necessary here? Doesn't F already provide what we need, or is there a critical difference between function-objects and non-function-objects? Clearly it won't be possible to have a constructor function using this technique. What happens the next time Object.create() is called? Is global function F overwritten? Surely it is not reused, because that would alter previously configured objects. And what happens if multiple threads call Object.create(), is there any sort of synchronization to prevent race conditions on F?

  • Backbone collection's URL depends on initialize function

    - by egidra
    I have a Backbone collection whose URL depends on the initialize function. When I create an instance of this Backbone collection, I pass in an ID to filter which instances of the model appear. Here is what the collection's code looks like: var GoalUpdateList = Backbone.Collection.extend({ // Reference the Goal Update model model: GoalUpdate, // Do HTTP requests on this endpoint url: "http://localhost:8000/api/v1/goal_update/?goal__id=" + this.goal_id + "&format=json", // Set the goal ID that the goal update list corresponds to initialize: function(goal_id) { this.goal_id = goal_id; console.log(this.goal_id); console.log(this.url); }, }); Of course, this doesn't work. this.goal_id is seen as being undefined. I guess because the URL is set before the initialization function is run.

  • Uploading multiple files asynchronously by blueimp jquery-fileupload

    - by Ryo
    I'm using jQuery File Upload library (http://github.com/blueimp/jQuery-File-Upload), and I've been stuck figuring out how to use the library satisfying the following conditions. The page has multiple file input fields surrounded by a form tag. Users can attach multiple files to each input field All files are sent to a server when the button is clicked, not when files are attached to the input fields. Upload is done asynchronously Say the page has 3 input fields with their name attributes being "file1[]", "file2[]" and "file3[]", the request payload should be like {file1: [ array of files on file1[] ], file2: [ array of files on file2[] ], ...} Here's jsFiddle, it's behaving weird so far in that it sends post request twice and the first one is cancelled. http://jsfiddle.net/BAQtG/24/ The core part of js code looks like this. $(document).ready(function(){ var filesList = [] var elem = $("form") file_upload = elem.fileupload({ formData:{extra:1}, autoUpload: false, fileInput: $("input:file"), }).on("fileuploadadd", function(e, data){ filesList.push(data.files[0]) }); $("button").click(function(){ file_upload.fileupload('send', {files:filesList} ) }) }) Anybody have idea how to get this to work? Updates Now thanks to @CBroe 's comment, the issue that request is sent twice is fixed. However the keys of request parameter is not correctly set. Here's updated jsFiddle. http://jsfiddle.net/BAQtG/27/

  • Loading/Displaying large amount of data on webpage.

    - by jb
    I have a webpage which contains a table for displaying a large amount of data (on average from 2,000 to 10,000 rows). This page takes a long time to load/render. Which is understandable. The problem is, while the page is loading the PCs memory usage skyrockets (500mb on my test system is in use by iexplorer) and the whole PC grinds to a halt until it has finished, which can take a minute or two. IE hangs until it is complete, switching to another running program is the same. I need to fix this - and ideally i want to accomplish 2 things: 1) Load individual parts of the page seperately. So the page can render initially without the large data table. A loading div will be placed there until it is ready. 2) Dont use up so much memory or local resources while rendering - so at least they can use a different tab/application at the same time. How would I go about doing both or either of these? I'm an applications programmer by trade so i am still a little fizzy on the things I can do in a web environment. Cheers all.

  • Arrays not matching correctly

    - by Nick Gibson
    userAnswer[] holds the string of the answer the user types in and is comparing it to answers[] to see if they match up and then spits out correct or wrong. j is equal to the question number. So if j was question 6, answers[j] should refer to answers[6] right? Then userAnswer[6] should compare to answers[6] and match if its correct. But its giving me wrong answers and displaying the answer I typed as correct. int abc, loopCount = 100; int j = quesNum, overValue, forLoop = 100; for (int loop = 1; loop < loopCount; loop++) { aa = r.nextInt(10+1); abc = (int) aa; String[] userAnswer = new String[x]; JOptionPane.showMessageDialog(null,abc); if(abc < x) { userAnswer[j] = JOptionPane.showInputDialog(null,"Question "+quesNum+"\n"+questions[abc]+"\n\nA: "+a[abc]+"\nB: "+b[abc]+"\nC: "+c[abc]+"\nD: "+d[abc]); if(userAnswer[j].equals(answers[j])) { JOptionPane.showMessageDialog(null,"Correct. \nThe Correct Answer is "+answers[abc]); } else { JOptionPane.showMessageDialog(null,"Wrong. \n The Correct Answer is "+answers[abc]); }//else }//if }//for

  • How do I handle the messages for a simple web-based live chat, on the server side?

    - by Carson Myers
    I'm building a simple live chat into a web application running on Django, but one thing I'm confused about is how I should store the messages between users. The chat will support multiple users, and a chat "session" is composed of users connected to one user that is the "host." The application is a sort of online document collaboration thing, so user X has a document, and users Y and Z would connect to user X to talk about the document, and that would be one chat session. If user Y disconnected for five minutes, and then signed back in and reconnected to user X, he should not get any of the messages shared between users X and Z while he was away. if users X, Y, and Z can have a chat session about user X's document, then users X and Y can connect to a simultaneous, but separate discussion about user Z's document. How should I handle this? Should I keep each message in the database? Each message would have an owner user and a target user (the host), and a separate table would be used to connect users with messages (which messages are visible to what users). Or should I store each session as an HTML file on the server, which messages get appended to? The problem is, I can't just send messages directly between clients. They have to be sent to the server in a POST request, and then each client has to periodically check for the messages in a GET request. Except I can't just have each message cleared after a client fetches it, because there could be multiple clients. How should I set this up? Any suggestions?

  • Search field using Ultraseek

    - by tony noriega
    So i realized today that using IE to do a search on my site, for instance the term "documents" returns the search results. if i use FireFox or Chrome the data in the input field is not recognized... now i looked at the code, and realized that there are no tags around the input fields... BUT if i put them, then IE does not work... what the heck do i do? <div class="searchbox" id="searchbox"> <script type="text/ecmascript"> function RunSearch() { window.location = "http://searcher.example.com:8765/query.html?ql=&amp;col=web1&amp;qt=" + document.getElementById("search").value; } </script> <div class="formSrchr"> <input type="text" size="20" name="qt" id="search" /> <input type="hidden" name="qlOld" id="qlOld" value="" /> <input type="hidden" name="colOld" id="colOld value="web1" /> <input type="image" name="imageField" src="/_images/search-mag.gif" width="20" height="20" onclick="RunSearch();" /> </div> </div> <!-- /searchbox -->

  • Update list dom only if list displayed

    - by Nikolaj Borisik
    Sometimes we use one store for few views(list, carousel,dataviews) and when we refresh(load, filter) store data, dom of all view that use this store will be rebuild, but some views is not displayed in this time, and may be will not show with these data. How we can refresh list dom only if it displayed, not every time when it store refresh? Issue examle Ext.define("Test.view.Main", { extend: 'Ext.tab.Panel', config: { tabBarPosition: 'bottom', items: [ ] }, constructor : function(){ this.callParent(arguments); var store = Ext.create('Ext.data.Store',{ data :[ {title : 'One'}, {title : 'Two'}, {title : 'Three'} ] }), firstList = Ext.create('Ext.List',{ title : 'tab1', store : store, itemTpl : '{title}', onItemDisclosure : function(){ store.add({title : 'Four'}); } }), secondList = Ext.create('Ext.List',{ title : 'tab2' , store : store, itemTpl : '{title}' }), thirdList = Ext.create('Ext.List',{ title : 'tab3', store : store, itemTpl : '{title}' }); this.add([ firstList, secondList, thirdList ]) ; } }); When tap on item in the first list, in store will be added new item. And dom of all list will be change although second and third list not displayed I see one option. Create one main store and create separate stores for each views. And when view show fill it store from Main store. But it look not good. Any other ideas?

  • How do I loop through elements inside a div?

    - by crosenblum
    I have to make a custom function for search/replace text, because firefox counts text nodes differently than IE, Google Chrome, etc.. I am trying to use this code, that I saw at Firefox WhiteSpace Issue since in my other function, I am looping numerically through nodes, which serves my functional needs perfectly, in other browsers. But refuses to work, as part of a search/replace function that takes place after some ajax content is loaded. Here is the code, that I have tried to get to work, but I must be missing the correct understanding of the context of how to loop thru elements inside a div. // get all childnodes inside div function div_translate(divid) { // list child nodes of parent if (divid != null) { // var children = parent.childNodes, child; var parentNode = divid; // start loop thru child nodes for(var node=parentNode.firstChild;node!=null;node=node.nextSibling){ // begin check nodeType if(node.nodeType == 1){ // get value of this node var value = content(node); // get class of this node var myclass = node.attr('class'); console.log(myclass); // begin check if value undefined if (typeof(value) != 'undefined' && value != null) { console.log(value); // it is a text node. do magic. for (var x = en_count; x > 0; x--) { // get current english phrase var from = en_lang[x]; // get current other language phrase var to = other_lang[x]; if (value.match(from)) { content(node, value.replace(from, to)); } } } // end check if value undefined } // end check nodeType } // end loop thru child nodes } }

  • Google Maps API - Marker not showing

    - by popnbrown
    I'm trying to add markers for every single row from a table, that sits on the page. The page is http://www.sravanks.com/first/2013ftcmap.php This is the JS code that's loading the markers: $(document).ready(function() { var mapOptions = { center: new google.maps.LatLng(39.740, -89.503), zoom: 7 }; var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions); var infowindow = new google.maps.InfoWindow(); /* City Markers */ var cityCircle = new Array(); var i = 0; $.each($('.events tr'), function(index, value) { var name = $(this).find('td:first()').html(); var address = $(this).find('.address').html(); var linkUrl = "http://www.sravanks.com/first/geocode.php?address=" + address; $.ajax({ url: linkUrl }).done(function(data){ var json = $.parseJSON(data.substring(0, data.length-1)); lat = json.results[0].geometry.location.lat; lng = json.results[0].geometry.location.lng; var latlng = new google.maps.LatLng(lat, lng); var marker = new google.maps.Marker({ position: latlng, map: map, icon: 'map-pointer-medium.gif' }); google.maps.event.addListener(marker, 'click', function() { infowindow.setContent(name); infowindow.open(map, marker); cityCircle[i] = new google.maps.Circle({strokeColor: '#00FF00', strokeOpacity: 0.8, strokeWeight: 2, fillColor: '#00FF00', fillOpacity: 0.35, map: map, center: latlng, radius: 144841}); i++; }); }); }); /*Team Markers*/ var markers = {}; var teamName, teamNumber, lat, lng, content; $.each($('.list tr'), function(index, value) { teamName = $(this).find('td.name').html(); teamNumber = $(this).find('td.number').html(); markers[teamNumber] = {}; lat = parseFloat($(this).find('td.lat').html()); lng = parseFloat($(this).find('td.lng').html()); content = "Name: " + teamName + "<br />Number: " + teamNumber; markers[teamNumber]['latlng'] = new google.maps.LatLng(lat, lng); markers[teamNumber]['marker'] = new google.maps.Marker({ position: markers[teamNumber]['latlng'], map: map }); google.maps.event.addListener(markers[teamNumber]['marker'], 'click', function() { infowindow.setContent(content); infowindow.open(map, markers[teamNumber]['marker']); }); }); google.maps.event.addListener(infowindow, 'closeclick', function() { for(var i=0;i<cityCircle.length;i++){ cityCircle[i].setMap(null); } }); }); I've got no errors, but the Team Markers do not show up. The strange thing is that the City Markers do show up. Some more info, the City Markers ajax call is just to a proxy that calls the google geocoding api. Again the link's at http://www.sravanks.com/first/2013ftcmap.php

Can I achieve this in a for loop or i need to use some thing else. Regards

  • Submit button on nested form submits the outer form in IE7

    - by Mike Christensen
    I have the following code on my Home.aspx page: <form id="frmJump" method="post" action="Views/ViewsHome.aspx"> <input name="JumpProject" /><input type="submit" value="Go" /> </form> However, when I click the "Go" button, the page posts back to Home.aspx rather than going to ViewsHome.aspx. I even tried adding some script to force the form to submit: <input name="JumpProject" onkeypress="if(event.keyCode == 13) { this.form.submit(); return false; }" /> But still even if I press ENTER, the Home.aspx page is reloaded. The only thing I can see that might be borking things is this form is actually a child form of the main POSTBACK form that ASP.NET injects into the page. I'm sure there's something stupid I'm missing and this post will get 800 downvotes instantly banishing me back into the n00b realm, but perhaps I haven't gotten enough sleep lately and I'm missing something stupid. This is on IE7 and an ASP.NET 4.0 backend. I also have jQuery libraries loaded on the page incase jQuery can improve this somehow. Thanks!

  • jQuery .getJSON() Not Parsing All Objects

    - by Brad
    I'm using jQuery's .getJSON function to parse a set of search results from a Google Search Appliance. The search appliance has an xslt stylesheet that returns the results as JSON data, which I validated with both JSONLint and Curious Concept's JSON Formatter. According to FireBug, the full result set is returned from the XMLHTTPRequest, but I tried dumping the data (with jquery.dump.js) and it only ever parses back the first result. It does successfully get all the Google Search Protocol stuff, but it only ever sees one "R" object (or individual result). Has anybody had a similar problem with jQuery's .getJSON? I know it likes to fail silently if the JSON is not valid, but like I said, I validated the results with several validators and it should be good to go. Edit: Clicking this link will show you the JSON results returned for a search for the word "google": http://bigbird.uww.edu/search?client=json_frontend&proxystylesheet=json_frontend&proxyrefresh=1&output=xml_no_dtd&q=google jQuery only retrieves the first "R" object, even though all "R" objects are siblings.
