Maybe this will work..

JScript code:

function endsWithToken(orig, str)
{
    return orig.lastIndexOf(str)===(orig.length-str.length);
}

I'm assuming str won't be longer than orig. If str's length is exactly one char more than orig's length, then orig.length-str.length returns -1 which evaluates the expression to true.

Fixed by using:

Javascript code:

---

return (orig.lastIndexOf(str)===orig.length-str.length) && (orig.length>=str.length);

For that triple '=', those are identity operators (opposed to a double '=' which is a equality operator). In almost all cases it is better to use identity operators instead of equality operators, unless there is a specific reason you need equality instead of identity.
