I'm trying to write code that will disable submit button (or all submit buttons) on the page to avoid double postback.

I thought of generating my own postback javascript function (and inject postback javascript using GetPostbackEventReference) but maybe there are some better ways to do this? Or maybe there is some other way to avoid double postbacks?

Update:

I also want to figure out the best place to call javascript, e.g. if I call following script in the onclick button handler then button's server click event won't be wired up.

$('input[type=submit]').attr('disabled', 'disabled')

This should help you

   1. $('form').submit(function(){  
   2.     $(':submit', this).click(function() {  
   3.         return false;  
   4.     });  
   5. });  

jQuery:

$('input[type=submit]').attr('disabled', 'disabled')

Otherwise, iterate through all document.getElementByTagName('input')

May be best to do this only for child nodes of the form that was submitted, though?

How about this:

$('input[type=button]').click(function() {
    $('input[type=button]').each(function() {
        $(this).attr('disabled', 'disabled')
    });
});

Anytime any button is clicked, every button on the form bees disabled.
