true

If I need one, I need to implement my own needs. please advise.

<script>
var whitespace=new String(' \t\n\r\f');
function trimL(s){
if(whitespace.indexOf(s.charAt(0))!=-1){
var j=0,i=s.length;
while(j<i&&whitespace.indexOf(s.charAt(j))!=-1)
j++;
s=s.substring(j,i);
}
return s;
}
function trimR(s){
if(whitespace.indexOf(s.charAt(s.length-1))!=-1){
var i=s.length-1;
while(i>=0&&whitespace.indexOf(s.charAt(i))!=-1)
i--;
s=s.substring(0,i+1);
}
return s;
}
function trim(s){
return trimR(trimL(s));
}

Thanks!!

Welcome.

The example code contains a markup error:

j&gt;=0

should perhaps read:

j>=0

Why do you present that in preference to what is in the FAQ?
