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

This code get all form fields with select list & checkbox etc.

var save_prms = $("form").serializeArray();
    $(save_prms).each(function( index, element ) {
        alert(element.name);
        alert(element.val);
    });
