Need jQuery.validate to prevent Ajax form submission

I am using jQuery.validate () to validate my form prior to submitting it. Now that I am using Ajax to submit my form, I have a problem.

Note. I am not using the jQuery plugin. It's just so clear :)

JQuery.validate () runs, but form submission is also executed.

I don't want the form to be submitted until the validator has been approved. Any suggestions from God on how I can do this?

UPDATE

I found the answer. I had to use submitHandler. Now my form only submits if all required fields are filled in.

and this is how:

if( jQuery('#my_form').length > 0 ) {
  jQuery("#my_form").validate({
     rules: {
       brand_name: "required",
       brand_email: {email: true },
       brand_description: "required"
     },
       submitHandler: function() { processRegistration(jQuery("#my_form").attr("id"), jQuery("#my_form").serialize());  }
  });  


}
