Handle A Callback Event Before It Performs The Default Href Function?

Mar 1, 2010

how to handle a callback of an event, before it performs the default href function.

<code>
<a href = '<?php $url ?>' onclick = myFunction(); return true;>Click Here</a>
</code>

I want the onclick event to finish completing and then perform the default href function, which is denoted by the "return true". The javascript "myFunction()" opens a window in a pop-up and it has a submit button in it. I would like to wait till this page loads in the pop-up window and only after the user clicks on the close button, the default href function needs to be carried out. I cannot figure out on how to get the callback from this event.

JQuery :: Href In Output Code Causing $getJson() Function To Try To Load Up A File With Href In Url

Jul 12, 2010

I'm using the following code (simplified version) to call a Json file, parse it and on each iteration, create a div with an ID of "tab". I'm using this with jQuery UI .tab() to create a listing with entries which have three tabs. Anyhow, the principle seems to work except that when I examine what's happening behind the scenes using Firefox console, I see that each href in the html code produced is causing the Json function to re-fire using the href as it's url target.

Handle Objects And The 'this' Keyword When Using Event Listeners?

Feb 24, 2009

So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:

Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>

And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:

[Code]...

But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.

JQuery :: Hides All Divs Except The First One (check The Site) On Load, Then Whenever Click A H3, It Performs As An Accordion?

Apr 5, 2011

I've got my accordion working.The html and jq are as follows

<div class="nav">
<h3><div></div>
<h3><div></div>
<h3><div></div>etc..
</div>
$(document).ready(function() {

This hides all divs except the first one (check the site) on load, then whenever I click a h3, it performs as an accordion, sliding the hidden div down and other visible divs back upI want to add another functionality. I want it to be like, if you click on a h3, and the next div is already open, it will hide that div. else, it performs this function. This would be a basic if/else then wouldn't it? I'm new to jq but I've done mIRC scripting in the past and I don't know how the selectors work yet

IE Not Stopping Default Event

Apr 5, 2007

I'm currently overriding function keys (F1 to F4) to perform other
actions. In order to do this the default popup windows of Help (F1),
Seach(F3) etc must be turned off. In FF it's easy enought to do using
the preventDefault and stopPropagation event functions.

IE's equivalent is supposed to be cancelBubble and returnValue,
however I can not seem to get them to stop no matter what I try.

Can someone please point out my error? The test code is below....

JQuery :: Event Animation Callback Doesn't Work Properly ?

Dec 9, 2010

This is my code:

I've set the animation to large numbers (1000) to make it very obvious.

The helper will show before the other fieldSets have been hidden. The show animation begins about half way through the hide animation. Since both elements are occupying the same space, this makes the container jump around in size as it breifly expands to fit one under the other.

JQuery :: 'return False' In Callback Of Click Event Not Working?

Jan 8, 2010

I have the following code

Code:
$('a').live( 'click', doIt() ) ;
...
function doIt() { return false }

However, the 'return false' does nothing. If I click a link the event is not stopped and the page it points to is loaded!

So, what could I do, given the above code, to stop the click event ?

UPDATE: I inspected jQuery object and changed doIt to

Code:
function doIt() {
$.Event.preventDefault();
$.Event.stopPropogation() ;
}

Does not produce errors, but didn't stop the event, but I feel I'm getting closer

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]....

Location.href Within OnClick Event

Jul 20, 2006

I am creating a send to a friend link on my site. The link will open a pop up window, which contains a form.

I have a function that opens the centered pop up window, and it is called like so (the function declaration resides in an external script):

Code:
onClick="newWindow('http://www.mysite.com/send.php','',',','')"
I now need to append the current page's URL to the end of the URL ike so:

onClick="newWindow('http://www.mysite.com/send.php?page=xxx','',',','')"
This is sso that I can then use PHP in the pop up toget the variable from the query string.

I know that I can use location.href to get the current page url, but am not sure how I would include it in the onClick.

I have tried the following:

onClick="newWindow('http://www.mysite.com/send.php?page=location.href','',',','')"
but that doenst work...

Has anybody got any ideas?
