JQuery validate doesn't work with IE

Question

I'm working on this website:

http://aimmgm.goexpo.mx/index.php/registro/generales

That's basically a form and what I'm trying to do is to validate it using a jquery plug in. It works just fine in Chrome and Firefox. But IE seems to have troubles with it since it doesn't validate the fields.

So, any hint of what could be wrong?

Thanks in advance.

Answer 1

$('#formId').submit(function(){
    if(!$(this).valid()){
       return false;
    }
});
