JQuery :: Automatically Perform A Function As Soon As The New Class Appears?

May 31, 2011

I'm using jquery file upload - when each file has uploaded, the name of the file appears, and I've added a check button:

<td colspan="2"><span class="ui-icon ui-icon-check"></span></td>

What I'd like to do is make jplayer fire off a "ding" sound as soon as each file is up.

For example (just to test)

$('.ui-icon-check').live('click', function() {
$(this).css("background-color","yellow");
});

needs an action, like a click or a mouseover or something. For each file that arrives, and therefore adds another instance of ui-icon-check, I'd like to fire an event. A weekend of googling has really only turned up Live Query from 2007, which works perfectly with

$('.ui-icon-check').livequery(function(){
$(this).css("background-color","yellow");
});

[Code]....

So am I totally mis-understanding the point of live, or just mis-using it?

I'm doing it this way rather than mess with the uploader code as he's updating the code all the time, and the more I can stay away from code code the better I think.

JQuery :: Perform A Function On All Elements Within A Class?

Jun 18, 2011

I'm sure this is much simpler than I have been making it seem in my head so I'm giving up and asking Basically I have a html document being dynamically created by php. In the markup I create some divs (the number of which changes between pages) all of which belong to the same class (class="div") and have id's of the same format (id="div_90001" or "div_88926773"). What I want to do is perform a function on eachelementin the class and extract the number in the id and then perform a function with the number (AJAX) and then return the results to the div (probably some extra markup)

I can handle all the AJAX parts, the extracting of the id number etc... I just can't make a function that will work on all elements in a class. I fear I am not making much sense, I'll try again cos I don't think I'd understand what's above. I have some divs that belong to a class, I want to perform the same function on each of the elements in the class. How is this done?

JQuery :: Hiding Empty Span - Ui-widget-header Class Appears To Be Stopping It From Hiding

Jan 30, 2010

I'm using the following css code which wrapped around a dynamically populated field;<span class="ui-widget-header platform ui-corner-all"></span>

When the span is empty I want to hide it, and I've used this jquery to do this.

However, the ui-widget-header class appears to be stopping it from hiding - if I remove this class it hides fine.

AJAX :: Perform A Php Function Rather Than Load A Page?

Feb 4, 2010

I have this code below:

Code:

$('#admintable').load("/includes/ajax.php?type=gallery&action=order&var=" + $.tableDnD.serialize());

The problem is that throughout my php project it calls different classes and definitions based on what modules are loaded.Is it possible to get it to load a function that is predefined rather than executing a page that will require me to once again declare all my variables and classes so I can perform just a simple db search.

Element.focus() Function Takes Ages To Perform?

Sep 28, 2010

My problem is that it takes ages to perform the element.focus() function. This is not a function I have written myself but is part of the Javascript language itself. There are probably a lot of reasons why this might be slow but I cannot find the right one. Let me describe my problem. We have a product which was created around 2004 and has been developed on since. The HTML and Javascript used for the product was based on a prototype which we then converted into a server based solution (we use Servlets/JSP).

Due to the nature of the prototype (and also the graphical layout) the major page consists of one huge HTML page which a lot of hidden DIV tags. These DIV tags are then toggled visible/invisible to make it look like we have a kind of tab functionality. We also do not load all tabs when we load the mail page, instead each tab is loaded into a hidden iframe and then with Javascript we grab the resulting HTML content and paste it into the main page, making that one tab visible while hiding all other tabs.

In one of these tabs we also do some more magic. The layout is as follows; we have sets of three columns each and then a lot of rows. Each set of three columns contains one text field per column. The last text field contains a percentage value and when edited, we check if the value is lower then before the edit and if it is, then we split the column, creating another set of three columns.

When we load the page the first time, there exists only one set of columns with the last column having the value 100. There can however easily be 100 rows as well. For the larger pages we can have (at load time) three columns which makes it 900 text fields. I do not know if this is much or not.So, with the above info, to my problem. First off, when I try to move the marker and click on a given field (so that the marker starts blinking on the selected field) it takes maybe 2-3 second (although not always, seems to be more the first time). If I then tab to the next field it goes very fast (like one would expect).When I try to edit a value (by simply adding or removing values) it again takes a very long time (the first time).

When I then try to tab, it takes ages (this happens always, not only the first time).My Javascript then. I have two events, onchange and onkeydown. onkeydown checks if a variable is set to true or not. If it is set to true, the method does nothing. If set to false it does a bunch of tests and sets the variable to true. onkeydown is what I think causes my first lag but the code is not really that advanced (no loops or anything). onchange does the same checks plus all the magic (with the split etc). One of the last things it does is try to set focus on the next text field and this goes extremely slow all the time.

We use IE8. We (sadly) have a lot of IE specific stuff so the site doesn't even work in Firefox. I have used IE8 Developer Tools and used the Profiler which basically gives a list of Javascript calls and their execution times. My own functions take basically zero time, but there are A LOT of calls to functions that are not named, or anonymous, according to the Profiler.

How do I find what the anonymous function calls are?Why is it the focus() function that takes time, can it (or is it) still some of our own Javascript that makes that function go slow, even though it is part of the Javascript language?Can it be the amount of elements on the page (900 text fields)? Is that much?Can it be IE8? Are there known issues with this?

Accessing Class Member Using This Inside An Anonymous Function Call In A Class Method?

Mar 28, 2010

I'm using jquery to make it easy for AJAX calls.

So I create a class: function cMap(mapID){//vars and stuff}

I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }

Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }

My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.

How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?

JQuery :: Own Slider Function - Automatically Detects Margin-top CSS Values

Mar 10, 2011

I recently wrote this slider function which automatically detects margin-top CSS values, then offsets the desired div, then simultaneously slides and fades the div in using jQuery's animate() function. It seems to work well with only one div. However if I set it up to slide multiple divs, I am having an issue I cannot figure out.

First, here's the example...[url]

You will have to few the example in Safari or Firefox as I have disabled the javascript in IE using conditional comments. You can view source to see my HTML, CSS, and Javascript.

My issue is this. The #header div slides in great. After a set delay, the #about div slides in. I want each div to slide in separately, one after another. However, when the #about div slides in, it seems to affect the #header element. When the #about div is in motion, I do not want the #header element to move.

JavaProcessAlert Function - Processing To Display Automatically

Sep 28, 2010

How to get the JavaProcessAlert() function to have its effect displayed on the page before and while the ActualJavaProcess() is working. I assume it has to go out of the script block and then back in, but have no idea as to how to make it do so automatically. I hope the code is understandable.

Code:
<html><head>
<script type="text/javascript">
function JavaProcessAlert(){
var Update = document.getElementById('DisplayedText');
Update.innerHTML = "Processing";
<!-- Not sure of how to get from here to body and back to ActualJavaProcess()
automatically for "Processing" to display while ActualJavaProcess() functions. -->
}function ActualJavaProcess(){
<!-- Takes time to complete function -->
Update.innerHTML = <!-- Whatever the result is -->;
}
</script>
</head>
<body>
<p id="DisplayedText" >Get Result</p>
<p><input value= "Start" onclick="JavaProcessAlert();" type="button"></p></form>
</body></html>

JQuery :: Stop Function - Add Class LI To UL

Oct 6, 2010

Is there a function to tell jquery to only do something on the first instance that matches then to stop. For example I add a class to a LI to an UL with the below but it adds the LI to all ULs under it.

$("div#container ul").prepend("<li>Home</li>");
Original code:
<ul><li>
<ul><li>item</li>
</ul></li>
</ul>

Code needed:
<ul>
<li>Home</li>
<li><ul>
<li>item</li>
</ul></li></ul>

Currently Output code:
<ul>
<li>Home</li>
<li><ul>
<li>Home</li>
<li>item</li>
</ul></li></ul>
