How to clear a value entered in text box if it is not alphabetic

[pkelly2003]

Question: On the client side, how do I automatically clear a value entered into a form text box if it is not alphbetic (not a letter)?

More specifically, I want to clear any numbers entered (as they are entered - before the form is even submitted).

it's usual to use javascript to validate the form contents before sending them to the server.

but there's some code here that u could modify and i think it'll do exactly what u want.

I tried that but it still entered the number that the user enters. I am using a function to check for numbers being entered using window.event.keycode. Here is what I have so far:

function checkKey
if (window.event.keyCode < 65) or (window.event.keyCode > 90) and (window.event.keyCode < 97) or (window.event.keyCode > 122) then
msgbox &quot;Please enter only letters in this box.&quot;, vbCancel
else

end if

end function

The form contains the following:
<input type=&quot;text&quot; name=&quot;Fname&quot; id=fname size=&quot;20&quot; onkeypress=&quot;checkKey&quot;><P>

The problem is that I can't prevent the number from being displayed in the form. How do I program something behind the 'Cancel' button (vbCancel) to prevent the number from being accepted and displayed?

I found my own answer!

I just needed to add this line to the function to make it work:
window.event.keycode = &quot;&quot;
