Trim string in JavaScript?

Question

How do I trim a string in JavaScript? That is, how do I remove all whitespace from the beginning and the end of the string in JavaScript?

Answer 1

The trim from jQuery is convenient if you are already using that framework.

$.trim('  your string   ');

I tend to use jQuery often, so trimming strings with it is natural for me. But it's possible that there is backlash against jQuery out there? :)
