Check if input empty on submit

Question

I\'ve been looking around for a solution to this, but can\'t seem to find any examples that work for me. Here\'s what I\'ve got so far:

$(\"#register-form\")         


        

Answer 1

You can't reference the values of all the form inputs like that.

var valid = true;
$('.required input').each(function(){
   if( $(this).val() == '' ){
      valid = false;
      $(this).addClass('highlight');
   }
});

The forms plugin will do this for you, by the way.
