Question

I want to cancel the post update in some circunstances without the need to reload the entire page.

I’ve tried:

// publish is the id of the Update button.
$('#publish').click(function(){
    return false;
});

// post is the id of the corresponding form.
$('#post').submit(function(){
     return false;
});

In both codes the form it’s not submitted but the Update button remain disabled and the ajax loader gif is showed.

How I can do this? Thanks in advance.

Finally, with the help of those who answered my question (specially to stealthyninja), I managed to bring working what I asked.

@karevn: This solution doesn’t break the autosave in current WordPress version (tested up to 3.2.1).

$('#publish').click(function(e) {
    if (!condition) {

        // Fix WordPress display to user.
        $('#ajax-loading').hide();
        $('#publish').removeClass('button-primary-disabled');               

        return false;
    }     
});
