[SOLVED] Form listener, get all inputs...

[SOLVED] Form listener, get all inputs...

I'm trying to get a script working which will go through a form, when it submits, and disable any fields which have no value...

Here's the code I have thus far; the script is not making it into the jQuery(':input',this).each(function().. line.. Anyone have any ideas?

jQuery(document).ready(function(){
    jQuery('form').submit(function(){
        jQuery(':input',this).each(function() {
            if(this.value=='')
                jQuery(this).disable();
        });
        return false;
    });
});
