jquery check if starts with for a link

I have the following in my .delegate:
link_id is the id of the link. I need to next say if that id started with RPwd then do something. Why doesn't ^= work in this case? 

    var link_id = $(this).attr('id');  //capture the id of the clicked link
    if (link_id ^= "RPwd") {

As far as I know ^= is not an operator in javascript. That could be your problem.

I think you are looking for

if ($(this).is('[id^="RPwd"]')) {
}

The starts with ^= selector is a jQuery object selector. You're doing a string comparison, and can therefore use indexOf()

if (link_id.indexOf("RPwd") === 0) {
   // Match
}
