If you have a string, and you want only a certain subset of characters, you could use the substr method:

[quote][pre]

var s = "sawkat";
var start = s.length - 3;
var lastThree = s.substr(start);
[/quote][/pre]

Hi there sawkat,

our friend Fotiman has given you the last three string letters, so here is the string less the last three letters...

<script type="text/javascript">
  var s="sawkat";
  var start=s.length - 3;
 
  alert(s.substring(0,start)); 
</script>

...to complete the collection. ;)

Yet another way to get the last 3 characters from a string - use regEx:
var s="sawkat";
var s2 = s.match(/.{3}$/); //gets last 3 of any characters from string
alert(s2); //'kat'

[astupidname]

Or if you want to remove the last 3 characters:
var s = "sawkat";
var s3 = s.replace(/.{3}$/,''); //replace the last 3 of any characters with a blank string ''
alert(s3); //'saw'

owow thanks my friend
