Heres a more object oriented way to define the trim function (copied
straight from the JScript documentation available for download from MSDN).
Its works for JScript 5 and JavaScript 1.3
// Add a function called trim as a method of the prototype
// object of the String constructor.
String.prototype.trim = function()
{
// Use a regular expression to replace leading and trailing
// spaces with the empty string
return this.replace(/(^\s*)|(\s*$)/g, "");
}
// A string with spaces in it
var s = " leading and trailing spaces ";
// Displays " leading and trailing spaces (35)"
window.alert(s + " (" + s.length + ")");
// Remove the leading and trailing spaces
s = s.trim();
// Displays "leading and trailing spaces (27)"
window.alert(s + " (" + s.length + ")");
