SCRIPT: Remove Leading and Trailing Spaces from String

[jschodde]

Here's a function to remove spaces from beginning and end of a string. Not much to it...hope you like it.

function Trim( strString ) {
    //Removes leading and trailing spaces from a string.

    try {
        //If parameter was null, return an empty string.
        if (strString==null) {
            return "";
        }
        
        var strNewString = "";
        var c = 0;
        for (i=0; i<strString.length; i++) {
            if (strString.charAt(i) != " " || c > 0) {
                strNewString += strString.charAt(i);
                if (strString.charAt(i) != " ") c = strNewString.length;
            }
        }
        return strNewString.substr(0,c);
    }
    catch(e) {
        //your error handler here
    }
    
}

For some of this stuff, remember that you can use the system language stuff in Javascript.

system.functions.strclpl(string)
system.functions.strclpr(string)

strString.replace(/^ +(.*?) +$/, "$1")

does the same thing, I believe.
