Jquery :: DOM After Load When The Callback Function Was Executed

Mar 26, 2010

I have an unordered list with each LI having an onclick event of "changeTabContent". When the page loads, I trigger the active LI's click. On a click, first thing I do is remove the previous results, which are a UL living under the "li.active" element. Next, I move the "active" class to the LI that was pushed and off the old one. Next, I add a loading animation to the screen. Next I append a new UL to the new "li.active" and use the load() method to insert a bunch of LI's from a different page. onSuccess, I remove the loading animation. [note 1] Next, you'll see a hack I added, more on that in a minute... Last two steps are to add a "more" link to the bottom of the returned li's, if a link was passed into the function, and finally I remove a handful of LI's (excluding more link) so there are only "x" on the screen.

My #1 problem is that the more link is not showing up at times, and the cleanList function is not removing LI's. I believe the problem is that with the load being async, sometimes those last two steps are being hit, but there is no LI's in the DOM yet. You can see I tried to run a hack so the while loop will execute when there is no "ul" yet. [note 1] - I tried to add the final two steps into the load() callback, but the LI's were NEVER loaded in the DOM when the callback function was executed.

JQuery :: $.post() Callback Executed No Data Passed

Jun 24, 2009

Here is my server side code:

Here is my javascript:

When i call alert(data), it says it is "undefined". i am new to jQuery, but this appears to mean that no data is being passed to the callback function even though i know the $.post() executed properly (the server side code is executing, and the other alert() tells me that it had a successful result and the callback is being made.

JQuery :: 1.6 Load Function Callback Bug In IE?

May 9, 2011

I think that in jQuery 1.6 the callback function is failing in IE(8).I've reverted back to jq1.4 and all is okay. Sample code that fails in 1.6 for IE

8;$('#add_edit_contact_content').load('company/ajax/dsp_addEditContactContent.cfm', function(){
alert('loaded');
});

The error reported is; Message: Could not complete the operation due to error

80020101.
Line: 16
Char: 11777
Code: 0
URI: http://localhost:8300/XXXXXXXX/application/scripts/jQuery/jquery-1.6.min.js

JQuery :: Using The Callback Function For .load()?

Aug 5, 2010

I'm a jQuery novice and I think I've gotten myself in over my head here. I have a #Calculatebutton with a click function attached which, when clicked, iterates through a form and sends the users input values, via $_GET, to a php script called'prepsession.php'. Here the inputs are validated and sanitized, a session is started and some session variables are created using the form input values. If there are any errors I want error messages displayed beside the form. Everything works fine up to this point.

If this script runs ok without giving any errors I would like to fire another php script called'printsummary.php'which accesses the previously created session variables and inserts them into a div #PanelContent. The reason I am usingseparatephp scripts for this is that I would like to be able to print my data in various different ways so I have numerous php print scripts accessing the session variables.

JQuery :: Function(data) Not Being Executed After $.post

Mar 22, 2010

I am new to all this but making good progress and having fun in the process. I have written quite a bit over recent weeks (including a few $.post / $.ajax calls) for various sites/applications but this one is really puzzling me. Here is a snippet of code that is causing me problems.

[Code]....

The problem is that execution jumps from line 2 to line 6 ... ignoring the function(data) and I am not sure why. I get the correct value of "team" arriving at the perl script .... and the perl writes the correct json back. I just can't think where else I need to look to debug this - as I said, I have done something similar 5-6 times over the last few weeks - all without a problem. So I am sure I am doing something stupid here.

JQuery :: Stop A Function/effect Being Executed?

Dec 6, 2009

I'm using jQuery and i have an animation effect which is executed via two methods:-

method 1: clicking on a nav link.

method 2: manually scrolling past a specified point.

Now, since method 1 will make the page scroll to the relevant anchor, by it's nature, it will trigger method 2.

What i need is a way to prevent method 2 from executing if method 1 is in operation.

JQuery :: Load Part Of Page With Ajax And BeforeSend Callback

Dec 10, 2009

I would like to achieve such thing, as to load some part of other page, like this:

$("#content").load("example.com/main.htm #content > div");

but I need to do a beforeSend callback, to fade out the current content, wait until it is fully hidden, and only then fade in with the received ajax request. But doing this, for example, with .ajaxSend, the content loads much quicker, then fadeOut is complete.

JQuery :: .load(callback) Event Is Not Fired On Dynamically Loaded Content?

Aug 3, 2010

I'm trying to load dynamically some content and I'd like to fire a function when all the newly added content (including images, iframes and scripts in it) are loaded:

var htmlStr='html string including images, iframes and scripts';
$("#contents").html(htmlStr).load(function(){
alert("all images, scripts and iframes are fully loaded, you can continue");
})

According tohttp:[url]....(at least how I understand it) this should work: Theloadevent is sent to an element when it and all sub-elements have been completely loaded. This event can be sent to any element associated with a URL,images, scripts, frames, iframes, and the windowobject.Unfortunatelly my function is never called. For the meantime I found a workaround:

var html=$('html string including images, iframes and scripts');
var elements=html.find("img,script,iframe,frame");
var loadCounter = elemets.length;[code]....

JQuery :: Using Return In Callback Function

Sep 30, 2010

I have some problem using the $.post function. I wrote a function that test if a username is already used in my database. That function must return true if the username is free and false in the other case. My problem is that I use the $.post function and I put the return true; and return false; in the callback function. So it's the callback function that returns true/false instead of my function !

Here is my code :
function validateName(){
$.post("ajax_is_name_used.php",
{name: $form_name.val()}, function(data) {
if (data.success == 1) {
$form_name.addClass("error");
return false; // Problem, we are in the callback function !
} else {
return true; // Problem, we are in the callback function !
}}, "json");}

JQuery :: Confirm Dialog Box - Callback Function

May 13, 2009

I'm trying to build a confirm dialog box. If found a nice plugin [URL] but the behavior is not like a normal confirm dialog box. You have to add a callback function to react on the ok/cancel buttons. Is it possible the simulate this behavior so I can have a function like this:
function showConfirmation(title, text){
//this displays a jQuery Dialog form and returns true/false
return myjQueryConfirm(title, text);
}

I tried this with the plugin:
function showConfirmation(title, text){
var res;
jConfirm(title, text, function (r) { res = r;});
return res;
}
But after the jConfirm is executed, the function proceeds and immediately returns res which is not defined.

JQuery :: How To Execute GetJSON Callback Function

})
.success(function() { alert("second success"); })
.error(function() { alert("error"); })
.complete(function() { alert("complete"); });}
