Jquery to display an alert when the Save button in clicked.

Hello,

I'm not a jquery guru, but I'm trying to learn.  Anyone know why this isn't working?

$("input[type='button'][name='ctl00$ctl39$g_c0acbd99_8b9a_451b_94d7_4e2f4a107495$ctl00$toolBarTbltop$RightRptControls$ctl01$ctl00$diidIOSaveItem']").submit(function(){

alert("Your request has been submitted.");
});

Thanks! Patti N.
