How dangerous is e.preventDefault();, and can it be replaced by keydown/mousedown tracking?

Question

I\'m working on a tracking script for a fairly sophisticated CRM for tracking form actions in Google Analytics. I\'m trying to balance the desire to track form actions accuratel

Answer 1

If you must have forms always work but tracking can be sacrificed if absolutely necessary, you could just try/catch it.

$('form').submit(function(e){
    try{
        e.preventDefault();
        var form = this; 
         _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action'));
        //...do some other tracking stuff...
        setTimeout(function(){
            form.submit();
        }, 400);
    } catch (e) {
        form.submit();
    }
});
