jQuery Mobile 'return false' on form submission -

i have form on jquery mobile site validate, , stop submission if validation not pass.

however, 'return false' not stop form being submitted, because jquery mobile submitting form via ajax. how can stop form submission?

$("#form").live('submit', function(){     alert('test');     return false; }); 

the above code fires alert, not stop form being submitted. if use data-ajax="false" on form tag works correctly, rather use ajax submission if possible.

use data-ajax="false" , bind own ajax form submission code runs if validation passes:

$("#form").live('submit', function() {     if (formvalidates)     {         $.post(...);     }      return false; });
