• JQuery - How do I count the number of elements selected by a selector?

  - by Josh

  I am using $().fadeOut() to fade items out in a list ( < li < /li). When the list is empty I wish to hide a parent object. I plan on doing this by checking in my trigger event that fades the list if the count of the objects is 0 then hide the parent element. I can use the fadeOut callback to remove the elements if necessary. The to the point question: How do I select li tags inside a ul and then get the total count of them using jquery?

• "Zooming" elements on a page while keeping the centre of enlargement in the centre of the window

  - by Acorn

  I'm trying to work out how to enlarge all elements on a page, but keep the centre of enlargement in the centre of the window. Example Page (up and down arrows to resize the image, you can also drag the image around) On this page, once the image reaches the top or the left side of the window the centre of enlargement changes. It also changes when you move the image. (exactly what you would expect) I'm thinking I'd need to take a completely different approach to achieve what I want. But I'm not sure what that approach is.. Any ideas?

• AJAX Closures and targeting 'this'

  - by Nick Lowman

  In the code example below the success callback function logs 'input#04.update' four times rather than each individual input, which makes sense seeing how closures work but how would I go about targeting each individual input using this. <input type="text" name="" id="01" class="update"> <input type="text" name="" id="02" class="update"> <input type="text" name="" id="03" class="update"> <input type="text" name="" id="04" class="update"> function updateFields(){ $('input.update').each(function(){ $this = $(this); $.ajax({ data: 'id=' + this.id, success: function(resp){ console.log($this); $this.val(resp) } }); }); }

• Capturing clicks even when stopPropagation has been called (ie by 3rd party code)?

  - by josh

  I want to detect any click that happens on a page (to close a custom context menu). I'm using jQuery and trying to do $(document).click(function(){ ...close my context menu ... }); However, I'm using some code that calls evt.stopPropagation() in the click handlers for certain elements on the page, and those clicks aren't making it up to my top-level handler. Is there any way of capturing those clicks? Can be jQuery or not jQuery, as long as it works cross-browser.

• How to get four following text inputs after each checkbox?

  - by Richard Knop

  I am traversing checkboxes like this: $('.day').each(function() { // here I need to get the following 4 text inputs in the HTML // and set some attributes on them }); After every checkbox there are four text input fields (there are also some div, span tags for CSS around them). So inside the loop above I need to get four text input fields that follow the checkbox in the HTML source so I can set some attributes on them. How would I go about that?

• Show AJAX content after images have loaded

  - by Ben4Himv

  I am developing my own lightbox kind of jquery plugin. Everything works but I want to hide the loaded content until the images have loaded in the browser from the AJAX call. I found a similar post and I am using the following script but the setTimeout function is what reveals the content and not the .load function. Am I trying to achieve the impossible? $.ajax({ url: 'meet/'+ pLoad + '.html', success: function(data) { var imageCount = $(data).filter('img').length; var imagesLoaded = 0; $(data).hide() .appendTo('#zoom_inner') .filter('img') .load( function() { ++imagesLoaded; if (imagesLoaded >= imageCount) { $('#zoom_inner').children().show(); } }); setTimeout( function() { $('#zoom_inner').children().show() }, 5000 ); } });

• Difference between jQuery click, bind, live, delegate & trigger functions( with example)

  - by I Like PHP

  Hello All, I know there are a lot of questions similar to this, but I want to know clear difference between all of these jQuery functions together on this page with an example, so that it will be very helpful for me to understand the mechanism of all of these functions. I have also read the reference on jQuery main site, but there is no comparison between these: $().click(fn) $().bind('click',fn) $().live('click',fn) $().delegate('td','click',fn) $().trigger('click') // UPDATED Please do not refer any link if there is a part of question belong to that. Please describe how all four function exactly works in different manner, and which should be preferred in which situation. Note: If there are any other function with same functionality/mechanism , then please share. Thanks a lot. Update i have also seen $(trigger) function? is this works similar to above four function ?

• Search box inside a div. Django

  - by Juliette Dupuis

  In my django app I display a list of elements (friends name) thanks to a loop: <div> {% for friend in group %} <p>{{ friend.name }} <p> {% endfor %} </div> I would like to create a search box on the top of my list in order to be able to find only the friends the user wants. I would like the search bar does not need to click to send the request (an example is the Airtime searchbox on top of the facebook friends list). I have absolutely no idea on how to do that, and I'm looking for hints or tips to start. Thank you very much for your help.

• Google Chrome && (cache || memory leaks).

  - by Alexey Ogarkov

  Hello All, I have a big problem with Google Chrome and its memory. My app is displaying to user several image charts and reloads them every 10s. In the interval i have code like that var image = new Image(); var src = 'myurl/image'+new Date().getTime(); image.onload = function() { document.getElementById('myimage').src = src; image.onload = image.onabort = image.onerror = null; } image.src = src; So i have no memory leaks in Firefox and IE. Here the response headers for images Server Apache-Coyote/1.1 Vary * Cache-Control no-store (// I try no-cache, must-revalidate and so on here) Content-Type image/png Content-Length 11131 Date Mon, 31 May 2010 14:00:28 GMT Vary * taken from here In about:cache page there is no my cached images. If i enable purge-memory-button for chrome (--purge-memory-button parameter) it`s not help. Images is in PNG24. So i think that the problem is not in cache. May be Google Chrome is not releasing memory for old images. Please help. Any suggestions. Thanks.
