This problem description deals with jQuery 1.3.2.

Often I get the following javascript error:

(E || "").replace is not a function in jquery-1.3.2.min.js

This error occurs when I apply the function jQuery.trim on a variable that contains a number instead of a string. So I have to replace the following javascript code:

var a = jQuery.trim(b);

The statement should be:

var a = jQuery.trim(new String(b));
