Hai Saravanan,

Here is the rectified code within a HTML


<html><head>
<title>Scripting Test: by Murugan K Patham</title>

<script language="javascript">
<!--
function myfunc()
{
   var myStr = new Array("~","!","#","$","%","^","&","*");
   var ss = document.f1.un.value;

   for(i=0;i<ss.length;i++)
   {
     myChr = ss.charAt(i);
     alert("I got the character : " + myChr);
     for(j=0; j<myStr.length;j++)
     {
       if(myChr == myStr[j])
       {
         alert("special character not allowed");
         myChr = "";
         break;
       }
     }
     document.f1.ab.value=document.f1.ab.value+myChr;
   }
}
//-->
</script>
</head>
<body>

<table border="2" cellpadding="8" bordercolor="red" align="center" font="courier">
<form name="f1">
<tr><td>
Enter Text: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<input type="text" name="un" maxlength="10" >
<input type="button" value="Test"
         onclick="myfunc()">
<input type="text" name="ab" maxlength="10" >
</form>
</td></tr></table>

</body>
</html>

I just added more things for debugging purpose. Maybe you can cut short those and take 
wharever you need.
