<div>
if you are using $.ajax({..}) you can set the properties off all the calls that you will use with &quot;$.ajax&quot; function.<br />
<br />
I.E.:<br />

<pre><code class="code-1 nolinks" id="code-20-40482875-1"><span>$.ajax({beforeSend:function(jqXHR,settings){</span>
<span>//DO SOMETHING BEFORE SEND THE DATA TO THE SERVER</span>
<span>}})</span>
</code></pre>
if its only a page that have forms then you can just set the &quot;submit&quot; event of the forms.<br />

<pre><code class="code-1 nolinks" id="code-20-40482875-2"><span>$('form').submit(function(){</span>
<span>//your process</span>
<span>//return false to cancel the submit</span>
<span>//return true to proceed with the submit</span>
<span>})</span>
</code></pre>
</div>


if you are using $.ajax({..}) you can set the properties off all the calls that you will use with "$.ajax" function.

I.E.:


$.ajax({beforeSend:function(jqXHR,settings){
//DO SOMETHING BEFORE SEND THE DATA TO THE SERVER
}})


if its only a page that have forms then you can just set the "submit" event of the forms.


$('form').submit(function(){
//your process
//return false to cancel the submit
//return true to proceed with the submit
})

Hi:<br />
<br />
I've got of client side processing on a web page which needs to be completed before the page posts back to the server.<br />
There are several operations on the page which could result in a postback, so I would like to universally intercept the postback on the client side before it occurs, complete some processing and proceed with the postback.<br />
<br />
What is the best way to do this in jquery?<br />
<br />
Thanks,<br />

How do I intercept all page postbacks in jquery before they occur?

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.
