JavaScript stops other Scripts on the Page

Well....!!!

I have Two Scripts on the Page for Two Purposes

1) For DropDown List

2) For POPUP Messages

When The Page Loaded Drop Down Works it Gives List

• Add New
• Modify
• Delete

and When I click Modify Or Delete To Execute The POP Message , The POP message Will Execute successfuly and when cancel or save Changes what ever I want On POP Message after when I return To the Page The Dropdown List Stop Functioning , its Not Drop the List above.

For Drop Down List I Used This JavaScript

 type="text/javascript">        $(function () {         $('.dropdown1').mouseenter(function () {             $('.sublinks1').stop(false, true).hide(); var submenu = $(this).parent().next();              submenu.css({                 position: 'absolute',                  top: $(this).offset().top + $(this).height() + 'px',                 left: $(this).offset().left + 'px',                 zIndex: 1000 });              submenu.stop().slideDown(300);              submenu.mouseleave(function () {                 $(this).slideUp(300); }); }); });  

While For POP Message I used

  type="text/javascript"> function ClearFields() { }; function CloseModal(msg) {               $('#myModal').modal('hide'); if (msg.length > 0) {                   alert(msg); } } function ShowModal() {               $('#myModal').modal('show'); }
