Fix for replace string in example function

[paynecrl97]

I'm on latest Chrome, and the line return "#" + myid.replace( /(:|\.|\[|\]|,)/g, "\\$1" ) results in only a single backslash being inserted before each match, as opposed to double backslash,

eg hello:world > hello\:world

Changing to return "#" + myid.replace( /(:|\.|\[|\]|,)/g, "\\\\$1" ) fixes this.
