问题
How can I trim all spaces from a string, even when they are caused by a non-breaking spaces ( )
For example:
var foo = $.trim($('<p> foo </p>').text());
The value of foo is " foo " instead of "foo"
UPDATE So, the problem wasn't jQuery's trim function. It works great. The problem is MSAjax's trim function. jQuery, rightly, uses function detection and if they don't exist, uses it's implementation.
Unfortunately, MSAJax's implementation of trim doesn't strip char 160 (non breaking space). However, the jQuery regex trim does, as it realizes that IE doesn't include char 160 in \s.
Why do stupid browser problems always end up being an issue with how M$ implements something???

Are you sure about that? I tried a slightly modified version of your snippet just now:
var foo = $.trim($('<p> foo </p>').text());
alert('#' + foo + '#');
and there were no spaces on either side of the 'foo'. http://jsfiddle.net/Ux7Wc/
This was using jQuery 1.6.2 in Firefox 5.

This is a bug before JQuery 1.4. Please upgrade.
