jQuery: How do I identify an element whose ID contains a dot?

Question

Here is my current code:

jQuery(document).ready(function($) {
  $("#edit-name").change(function() {
    $("#Membership_UserName").val($(this).val());
  });
  $("#edit-pass-pass1").change(function() {
    $("#Membership_PassWord").val($(this).val());
  });
  $("#edit-pass-pass2").change(function() {
    $("#.Verify_Password").val($(this).val());
  });
});

Everything works fine, except for updating the value of the element whose ID is .Verify_Password. The reason seems pretty apparent to me (that jQuery is getting confused after seeing # and . right next to each other) but maybe that's wrong...

Regardless, the ID can't be changed because it's being sent to a remote endpoint and it needs to match on that end.

So my question is: is there a way to tell jQuery that .Verify_Password is an ID (and not a class)?

You could just use `document.getElementById()` and wrap that in jQuery. — Ja͢ck, Aug 24 '13 at 04:42

yes you can do this by escape it.

$('#\\.Verify_Password');

OR

$("[id='.Verify_Password']")

I doubt that the latter will be optimised by jQuery. – Ja͢ck Aug 24 '13 at 04:44

Try $("#\\.Verify_Password").val($(this).val()); or read up on jQuery selector value escaping

You should double escape it

 $("#\\.Verify_Password").val($(this).val());

Check this jQuery doc for more info, Few examples -

// Does not work
$("#some:id")

// Works!
$("#some\\:id")

// Does not work
$("#some.id")

// Works!
$("#some\\.id")

If you indicate a selector with # then it will be an ID or if you indicate a selector witn . then it will be an CLASS.

If you didnt know whether it is an id or class then try like

$("#edit-pass-pass2").change(function() {
    $("#\\.Verify_Password").val($(this).val());
});
