remove save button on a particular page
jQuery(document).ready(function() {
 if (window.location.pathname == '/recruiterForm/2') {
      jQuery('input#edit-submit').hide();
      }
});

i have solved this problem using jquery.I have used window.location.pathname.This property returns the pathname of current page.if pathname is equal to the required url then i am hiding the save button by using the save button id.This solution works for me.
