Hi friend,

code to solve the problem :

<script language="javascript" type="text/javascript">
function validateZIP() {
var val = document.passform.password.value;
if(!isAlphabetic(val))
{
alert("Please enter valid character [a-z][A-Z].");
document.passform.password.focus();
return false;
}
return true;

}

function isAlphabetic(val)
{
if (val.match(/^[a-zA-Z]+$/))
{
return true;
}
else
{
return false;
}
}

</script>
<form name="passform" onSubmit="return validateZIP();">
Password: <input type="password" size=30 name="password">
<input type=submit value="Submit">
</form>
