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!

The String. trim() method # You can call the trim() method on your string to remove whitespace from the beginning and end of it. It returns a new string.
The $. trim() function removes all newlines, spaces (including non-breaking spaces), and tabs from the beginning and end of the supplied string.
Use the . rstrip() method to remove whitespace and characters only from the end of a string.
To remove whitespace characters from the beginning or from the end of a string only, you use the trimStart() or trimEnd() method.
You can use a regex:
str = str.replace(/\s*$/,"");
It says replace all whitespace at the end of the string with an empty string.
Breakdown:
\s* : Any number of spaces$ : The end of the stringMore on regular expressions:

For some browsers you can use:
str = str.trimRight();
or
str = str.trimEnd();
If you want total browser coverage, use regex.
