Hi Eric,

Thanks a lot for your help in this regard. This regards to the double byte which is like charset is UTF-8 and the usage of Japanese/Chinese Keyboard. The "%" in this is different than that we use in regular keyboards.Its of a double byte one.

I'm pasting the simple code for this.

<html<
<script language="Javascript"<
function Check()
{
alert(document.f1.t1.value);
if(document.f1.t1.value.length == 1)
{
if(document.f1.t1.value == "%")
{
alert(document.f1.t1.value.length);
}

}
}

</script<
<body<
<form name="f1" action="" method=""<
<input type="text" name="t1"<
<input type="button" value="Submit";
</form<
</body<
</html<

Please kindly help in this regard!!!

Thanks
