How to encode and decode the password by javascript.
please give the syntax of this problem.

hello varun,
In javascript, we encode the password or any string by using the escape() method and decrypt the string by used unescape() methods.

for example
<script type="text/javascript">
  var strValue = "this is the new password";
 var strvalue1=document.writeln(escape(strValue));
 document.write(unescape(strvalue1));
</script>
