Can a URL trigger an action on jQuery?

I know how to invoke a URL with jQuery. How to do the reverse? Can a URL will lead to execute the following jQuery code just as the signin division is clicked?

  2.         $(document).ready(function() { 
  3.             $(".signin").click(function() {
  4.                 $("fieldset#signin_menu").toggle();
  5. $(".signin").toggleClass("menu-open");
  6.             });
  7. $("fieldset#signin_menu").mouseup(function() {
  8. return false
  9. });
  10. $(document).mouseup(function(e) {
  11. if($(e.target).parent("a.signin").length==0) {
  12. $(".signin").removeClass("menu-open");
  13. $("fieldset#signin_menu").hide();
  14. }
  15. });
  16.         });
