Remove Trailing Characters with Javascript

This is not CF but it sure comes in handy.

If for any reason you need to get rid pesky trailing characters, here's the script:

<script>
function trimTrailingChars(s, charToTrim)
   {
     var regExp = new RegExp(charToTrim + "+$");
     var result = s.replace(regExp, "");

     return result;
   }
</script>




And here is how you use it in your code:

var sText = trimTrailingChars(sText, ',');


Note the red text above. Change the comma to whatever you want to get rid of.
