How to select html nodes by ID with jquery when the id contains a dot?

Question

If my html looked like this:

Answer 1

This is documented in the jQuery selectors API:

To use any of the meta-characters (such as !"#$%&'()*+,./:;<=>?@[\]^`{|}~) as a literal part of a name, it must be escaped with with two backslashes: \\. For example, an element with id="foo.bar", can use the selector $("#foo\\.bar").

In short, prefix the . with \\.

$('#SearchBag\\.CompanyName')

The problem is that . will match a class, so $('#SearchBag.CompanyName') would match

. The escaped with \\. will be treated as a normal . with no special significance, matching the ID you desire.

This applies to all the characters !"#$%&'()*+,./:;<=>?@[\]^`{|}~ which would otherwise have special significance as a selector in jQuery.
