Well, it's a loop, but I suspect higher-level language TRIM functions are
also loops. Sorry if I'm the 83rd person to respond.
function Trim(elt) {
// Trim leading blanks
while (elt.value.charAt(0) == " ") {elt.value =
elt.value.substr(1,elt.value.length)}
// Trim trailing blanks
while (elt.value.charAt(elt.value.length-1) == " ") {elt.value =
elt.value.substr(0,elt.value.length-1)}
}
