  • Javascript toggle using custom attributes

    - by Jacob
    Can't seem to get this to work for me, can anyone offer me some help? http://codepen.io/anon/pen/kABjC This should open and close a section of text based on click, it takes the ID # which is just a digit (1,2,3,4,etc) and using that id targets an id to open and close the section. Javascript $(document).ready(function(){ $('.classclick').click(function(){ $('#class'+$(this).Attr('data-id')+"show").show(400); }); }); HTML <div class="classes"> <?php foreach ($classes as $class): ?> <div class="class"> <div class="classclick" data-id="<?=$class['cid']?>"> <div class="class-title"> <?=$class['className']?> </div> <div class="class-intensity"> Intensity: <?=$class['classIntensity']?> </div> </div> <div class="class-show hidden" id="class<?=$class['cid']?>show"> <div class="class-inner-content"> <div class="two-thirds"> <?=$class['classDesc']?> </div> <div class="one-third"> Things To Know: asdfasd asdf afsdadfs fsda dfsa dfsadfsa </div> </div> </div> </div> <?php endforeach; ?> </div>

  • Android -- Object Creation/Memory Allocation vs. Performance

    - by borg17of20
    Hello all, This is probably an easy one. I have about 20 TextViews/ImageViews in my current project that I access like this: ((TextView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Text)).setText(""); //or ((ImageView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Right)).setVisibility(View.INVISIBLE); My question is this, am I better off, from a performance standpoint, just assigning these object variables? Further, am I losing some performance to the constant "search" process that goes on as a part of the findViewById(...) method? (i.e. Does findsViewById(...) use some sort of hashtable/hashmap for look-ups or does it implement an iterative search over the view hierarchy?) At present, my program never uses more than 2.5MB of RAM, so will assigning 20 or so more object variables drastically affect this? I don't think so, but I figured I'd ask. Thanks.

  • How to pass object in :with field for a link_to_remote call

    - by mathee
    I have an object elem that I'd like to pass to the remove_tag_from_cart method. Here is my attempt: -elem = @tags[1] #{elem.name}#{link_to_remote image_tag('x.png'), :url => {:controller => 'questions', :action => 'remove_tag_from_cart'}, :with => {:tag_to_remove => :elem}} The :with clause isn't working correctly. The image does not even show up. If I take out the :with clause, then the link properly shows up and calls the method correctly, but I need the elem object in order to remove it from the cart. Suggestions?

  • Fetching JSON object from Servlet Java

    - by ChrisA
    I want to create an application that will fetch a JSON object from a servlet to deserialize it, and then use its variables to do other things. My servlet has the following code in the doPost: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ObjectOutputStream os; os = new ObjectOutputStream(response.getOutputStream()); String s = new String("A String"); Gson gson = new Gson(); String gsonObject= gson.toJson(s); os.writeObject(gsonObject); os.close(); } Now, while the servlet is running, I can access it via a browser, if I post same code in the doGet method, that would download a servlet file, which is not what I want. What should I use in my second application that would connect to the servlet, fetch the object, so that I can manipulate it later? Thanks in advance.

  • accordion tab open at different times

    - by user3279193
    I am using an asp classic and on the page I have a J-Query accordion. I want one tab to be open if the value that the asp prints out is greater than zero, if not , I want them all to be closed, this is an example of what I've got: J-Query: $(function() { $( "#accordion" ).accordion({ heightStyle: "content", collapsible: true, active: false }); }); HTML/ASP: <div id="accordion"> <h3>Tab1</h3> <div> <p>Hello World</p> </div> <h3>Tab2</h3> <div> <p>Hello World</p> </div> <h3>Tab3</h3> <div> <p>Hello World</p> </div> <h3>Results (<%=number%>)</h3> <!--if number > 0 then open tab else close all tabs--> <div> <p>Hello World</p> </div> </div>

  • Font alignment problem in webkit based browsers

    - by Mike
    Here is the code: <style type="text/css"> html, body {font:0.9em/1.2em arial, verdana, helvetica, sans-serif;} #todayOn {background-color:#efefef; repeat-x top left;border-bottom:1px solid #ddd;border-top:1px solid #ddd;height:52px;margin:15px 0;} #todayOn #pageTitle {float:left;padding-left:3px;} #todayOn #pageTitle h2 {color:#feb425;font-size:32px;margin:10px 0 0 0;padding:0;} #todayOn #pageTitle h2 em {color:#7498c0;display:block;font-size:14px;font-style:italic;font-weight:normal;line-height:20px;padding:5px 0 0 0;} </style> <div id="todayOn"> <div id="pageTitle"> <h2>TODAY <em>on this page.com</em></h2> </div> </div> In Firefox, IE (6+), Opera, etc. the subheader "on this page.com" displays vertically how I want it to. In Webkit browsers like Chrome and Safari, it's pushed down a couple more pixels. What's the prob? Thanks.

  • SSIS web service task producing "object reference" error

    - by gfrizzle
    Our care management system uses a web service to import data. I've successfully executed one of its methods using soapUI, and now I want to replicate this with an SSIS 2008 web service task, but I'm running into a problem. I've created the "HTTP Connection Manager" successfully, and specified the location of the "WSDLFile", but when I go to the Input tab and select the Service from the dropdown (there is only one), I get an "Object reference not set to an instance of an object" error, and and the Method dropdown is empty. Any idea what this is trying to tell me?

  • Why does my floating div push around other divs?

    - by Meke
    I have a div which has a table which has a google map. I want to place a info box within the google map external to the map, just floating on top But I can't seem to get it right, the info div just pushes around the google map despite being on top of the map...

  • Find a control by String from asp.net Web service

    - by jphenow
    Well since it seems relatively difficult to send the object of a WebControl over JSON using jquery.ajax() I've decided to send the name of the control as a string because I know how to do that. Then I promptly realized that, from a web service, I don't actually know how to search for a control by ID name. Since its a service I can't seem to get Control.FindControl() to work so does anyone have ideas or suggestions? All I'm trying to do is call a databind() on my radcombobox. Thanks in advance! For any of you that knows anything about asp.net/rad controls - I'm basically updating a database and want the radcombobox to be in sync with that database again after adding something, before I autoselect what was just added. Other than databind do i have to call anything to refresh that list? Thanks again!

  • Google Chrome is doing things wrong again

    - by Stefan Liebenberg
    Chrome is wrongly reporting width and height values for images during, or just after, load time. Jquery is used in this code example: <img id='image01' alt='picture that is 145x134' src='/images/picture.jpg' /> <script> var img = $( 'img#image01' ) img.width() // would return 145 in Firefox and 0 in Chrome. img.height() // would return 134 in Firefox and 0 in Chrome. </script> If you put the script in a onload function, the result is the same. but if you run the code a few seconds after the page has loaded, chrome returns the correct result. <script> function example () { var img = $( 'img#image01' ); img.width() // returns 145 in both Firefox and Chrome. img.height() // returns 134 in both Firefox and Chrome. } window.setTimeout( example, 1000 ) </script> Also if you specify the width and height values in the img tag, the script seems to work as expected in both Firefox and Chrome. <img id='image01' src='/images/picture.jpg' width=145 height=134 /> But as you cannot always control the html input, this is not an ideal workaround. Can jQuery be patched with a better workaround for this problem? or will I need to specify the width and height for every image in my code?

  • JavaScript onClick() Display

    - by junaidkaps
    I have an array consisting of several objects containing Strings. I am successfully able to display the array by using: <td><p onclick="theMiddle(this)">The Middle</td> As you see from the td tag this is part of a table. Issue is that the browser opens up a new page to display my text. I have been trying to display the array above my table in a p tag. //JavaScript var arrayTheMiddle = new Array (showName.theMiddle, beginingTime.theMiddle, network.abc, duration.thirty, rating.general, description.theMiddle, showImage.theMiddle); function theMiddle(obj){ for(i=0; i < arrayTheMiddle.length; i++) { document.write(arrayTheMiddle[i] + "<br>"); } } //HTML File <p>Would like the array/function displayed here while the user clicks within the table below (entire table has not been listed)</p> <td><p onclick="theMiddle(this)">The Middle</td> Unfortunately I am constantly failing at utilizing get element by id to call my function which consists of an array. I have searched for all sorts of stuff, yet frankly I'm lost. Not even sure if my approach is correct at this point. I'm sure this is one of those simple things that are blowing over my head!

  • jQuery slideDown + CSS Floats

    - by danilo
    I'm using a HTML Table with several rows. Every second row - containing details about the preceding row - is hidden using CSS. When clicking the first row, the second row gets showed using jQuery show(). This is quite nice, but I would prefer the slideDown-Effect. The problem is, inside the details row, there are two floating DIVs, one floating on the left, and one on the right. Now if i slideDown the previously hidden row, the contained DIVs behave strange and "jump around". See this animated gif to understand what I mean: http://ich-wars-nicht.ch/tmp/lunapic_127365879362365_.gif The markup: <tr class="row-vm"> <td>...</td> ... </tr> <tr class="row-details"> <td colspan="8"> <div class="vmdetail-left"> ... </div> <div class="vmdetail-right"> ... </div> </td> </tr> The CSS: .table-vmlist tr.row-details { display: none; } div.vmdetail-left { float: left; width: 50%; } div.vmdetail-right { float: right; width: 50%; } And the jQuery code: if ($(this).next().css('display') == 'none') { // Show details //$(this).next().show(); $(this).next().slideDown(); } else { // Hide details //$(this).next().hide(); $(this).next().slideUp(); } Is there a way to fix this behavior, and to implement a nice slideDown-effect?

  • Stuck with the math in a Flash project, would parsing engine help?

    - by VideoDnd
    I've been stuck with the math in a Flash project? It's a loose design pattern my director formulated. My goal is to keep the project object oriented, and get 'non Flash obstacles' off my plate. Do you recommend using parsing engines for processing math? XML values going to AS3, updating a changing acceleration formula. I don't hate math, but it just doesn't seem OOP or good project planning to have the math stuck in Flash. Your comments are welcome.

  • Hide All But First Matching Element

    - by Batfan
    I am using jquery to sort through multiple paragraphs. Currently I have it set to show only paragraphs that start with a current letter. But now, I would like to consolidate further. If the text between the paragraph tags has multiple instances, I would like all but the first hidden. This is what I have so far but, it is not working. var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ jQuery(this).addClass('current-series'); jQuery(this).html(letter + '<span class="hidden">'+jQuery(this).text().slice(1)+ '</span>'); } else{ jQuery(this).hide();} }) } Update: Sorry guys, I know this is kind of hard to explain. Here's a basic example: The selected letter is B The values returned are: Ball Ball Ball Boy Brain Bat Bat Each of these values is in a paragraph tag. Is there a way to consolidate to this? Ball Boy Brain Bat

  • Recommendation for tool/framework that follows the naked objects pattern?

    - by Marcus Munzert
    I am searching for a tool/framework that follows the naked objects pattern and is written in Java. I know about tools like for instance JMatter, Naked Objects and Domain Object Explorer. That's not exactly what I am searching for, though. Open source would be great, but doesn't need to be. My intention is to use that tool/framework for the purpose of model-driven software development to do the modeling part. Ideally, such a tool/framework would provide the option to use JPA to store/load objects.

  • How to convert "9:00 PM EST" to a Date object

    - by Bara
    I am developing an Android application and require some basic datetime manipulation. I have a Date object (from Java.util.Date) holding a specific date. I need to add a specific time to it. The time I have is a string in this format: "9:00 PM EST" How would I "add" this time to the previous date? If the Date object currently has: "4/24/10 00:00:00" How would I change it to instead be: "4/24/10 09:00:00 EST" I would prefer to do this without the use of an external library, if possible.

  • Disabling browser print options (headers, footers, margins) from page?

    - by Anthony
    I have seen this question asked in a couple of different ways on SO and several other websites, but most of them are either too specific or out-of-date. I'm hoping someone can provide a definitive answer here without pandering to speculation. Is there a way, either with CSS or javascript, to change the default printer settings when someone prints within their browser? And of course by "prints from their browser" I mean some form of HTML, not PDF or some other plug-in reliant mime-type. Please note: If some browsers offer this and others don't (or if you only know how to do it for some browsers) I welcome browser-specific solutions. Similarly, if you know of a mainstream browser that has specific restrictions against EVER doing this, that is also helpful, but some fairly up-to-date documentation would be appreciated. (simply saying "that goes against XYZ's security policy" isn't very convincing when XYZ has made significant changes in said policy in the last three years). Finally, when I say "change default print settings" I don't mean forever, just for my page, and I am referring specifically to print margins, headers, and footers. I am very aware that CSS offers the option of changing the page orientation as well as the page margins. One of the many struggles is with Firefox. If I set the page margins to 1 inch, it ADDS this to the half inch it already puts into place. I very much want to reduce the usage of PDFs on my client's site, but the infringement on presentation (as well as the lack of reliability) are their main concern.

  • iphone singleton object synchronization

    - by user127091
    I'm working on an iphone app but this is probably a general question. I have a singleton Model class and there would be scenarios where multiple NSOperations (threads) would exist and work with the singleton object. If they all call the same method in this object, do i need to have some locking mechanism? Or can this method be executed only one at a time? I do not have a computer science background but my guess is that all threads would have their CALL to the same address (this method). Also can you please suggest a good beginner programming book that discusses general programming concepts. I don't have the brains for Knuth kinda books.

  • Find whether a particular cell of a table has an img tag

    - by SilentPro
    I am generating a table dynamically using Django. The same table template is used to generate a variety of tables depending on the data supplied. In one scenario a particular column contains image tags. Since my table is editable (using jquery) the image cell also becomes editable and removes my content. I want some special behavior on double click of such cells like say upload an image. How do I accomplish this with a jquery? My script for making the table editable is given below. $(function() { $("td").dblclick(function() { var OriginalContent = $(this).text(); $(this).addClass("cellEditing"); $(this).html("<input type='text' value='" + OriginalContent + "' />"); $(this).children().first().focus(); $(this).children().first().keypress(function(e) { if (e.which == 13) { var newContent = $(this).val(); $(this).parent().text(newContent); $(this).parent().removeClass("cellEditing"); } }); $(this).children().first().blur(function() { $(this).parent().text(OriginalContent); $(this).parent().removeClass("cellEditing"); }); }); });

  • iFrame in a Content Editor Web Part

    - by Music Magi
    Hi - I'm creating a page with two web parts: one with a search UI and another that displays the results. I'm using Content Editor Web Parts for both, but no matter how hard I try I can't seem to display more than a fraction of the results page in the content editor web part with the iFrame. The width seems to set fine, but no matter how I set the height (I've tried in-line, using CSS and using Javascript/JQuery), I cannot change the height of what is displayed. If I make the height something ridiculous like 3000px, I can see the empty space below, but it still only shows a small amount of the resulting page at the top of this iframe section. I've observed the HTML and the iFrame takes up all the space it's supposed to, but only shows that small sliver of the actual page the iFrame is displaying. I've tried numerous approaches from numerous articles but have come up short (pun intended). Does anyone have any experience with this or have indication as to why it would display this way or what I have to do to make this iFrame fill up the entire web part space? Thanks in advance
