custom JavaScript Trim function

crmpicco · January 18th, 2006, 12:06 PM

I have the function 'Trim'.
However, I am experiancing errors as soon as it gets to
return str.replace(/^\s*|\s*$/g,"");
Is there something wrong with this code?

Code:

/*
FUNCTION NAME: Trim
Removes any white space from either side of the string
*/
function Trim(str)
{
  return str.replace(/^\s*|\s*$/g,"");
}

Thanks,
Picco

Where is this running? Some older browsers don't support regular expressions, especially with the // delimiters.

A more JavaScript way of doing this would be:

Code:

String.prototype.trim = function(){return this.replace(/^\s*|\s*$/g,"");}
alert("!" + "  my string with spaces   ".trim() + "!");
