javascript - Jquery Validation without form submission -

i have form, on have button - when user clicks button add, function called adds new row table in same form, using javascript.

i have used jquery validation plugin,the problem have validation fires when use submit button,but not when button clicked, runs function.

i understand why - validation plugin wants form submitted.

is there way can cause validation run , return result? function can either nothing if validation fails, or go ahead , post user entered data function if validation passes. need without form submitting.

any appreciated - i've tried few ideas found whilst googling on this, nothing has worked far.

thank beforehand.

if ($j('#form1').validationengine({ returnisvalid: true })) {   //is valid } 

or if mean: http://docs.jquery.com/plugins/validation

$("#myform").validate({  submithandler: function(form) {    // other code    return false;  } });
