@JMRKERApr 06.2008 — Do you have any code that you want analyzed?

If you are trying to enter special characters,

it will depend upon your character set defined, for example:

<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">

and unicodes you enter.

Do a search on 'unicodes' and 'character sets' for more information.

Thanks for your post.Actually what I am trying is that the textbox will take only characters between (a-z) and (A-Z).

No numerics and special characters will be allowed.

So what I was planning to check the input based on ascii code of each character...but dont know how to write it in the javascript function.

@JMRKERApr 06.2008 — Do you need to check the input as typed

or do you want to check the final text when entry is completed?

Thanks very much for your reply.

The input will be checked after the final form submission.

The onlick function is ready and other validations are also going ok.

Its solved...?

Here is the code:

[CODE]var ch= "!@#$%^&*()+=-[]\';,./{}|":<>?";
for (var i = 0; i < document.f.firstname.value.length; i++) {
if (ch.indexOf(document.f.firstname.value.charAt(i)) != -1) {
document.getElementById('err').innerHTML="This firstname contains illegal characters.";
document.getElementById('err').style.display="";
document.f.username.focus();
return false;
}
}[/CODE]

Thanks.
