Gives:

function LTrim(str) {
  for (var k=0; k<str.length && str.charAt(k)<=" " ; k++) ;
  return str.substring(k,str.length);
}
function RTrim(str) {
  for (var j=str.length-1; j&gt;=0 && str.charAt(j)<=" " ; j--) ;
  return str.substring(0,j+1);
}
function Trim(str) {
  return LTrim(RTrim(str));
}

And then you simply Trim(YourStringName)
