Trimming whitespace from the END of a string only, with jQuery

Question

I know of the jQuery $.trim() function, but what I need is a way to trim whitespace from the END of a string only, and NOT the beginning too.

So

  str ="     this is a string     ";

would become

  str ="     this is a string";

Any suggestions?

Thanks!

You can use a regex:

str = str.replace(/\s*$/,"");

It says replace all whitespace at the end of the string with an empty string.

For some browsers you can use: str = str.trimRight(); or str = str.trimEnd();

If you want total browser coverage, use regex.
