Numeric Text

Hello all,

Is there any way makes me prevent the user from entering characters in
a Text object
I want the Textbox to accept only numeric values when writting into it.

1. There is no Text object. You probably mean an input[type="text"]

2. No, client-side script support may be not present, so do not bother.
You need to validate this server-side anyway.

This might help:

<script type="text/javascript">
function filter(e) {
var ascii;
if (e && e.charCode) {
ascii = e.charCode;
} else if (event && event.keyCode) {
ascii = event.keyCode;
} else {
return true;

if (ascii < 48 || ascii > 57) return false;
return true;

window.onload = function () {
document.forms[0].elements['test'].onkeypress = filter;
document.forms[0].elements['test'].onpaste =
function () {
return false;
<input type="text" name="test" />

I apologize for those of you who think I'm posting on the same topic. It is not that I don't appreciate all of your comments - and I'm definitely reading them all - but I think I have a differing opinion of how I want to handle the 'user experience' in the application I'm creating. While I know I could allow the user to enter in number and alpha text - in a text box - and then tell them when the execuate a command "This is not numeric data", I...

Hi, I have a number of text boxes for the user to input either numbers, or letters. Sometimes, the entry must be numeric. So I was thinking of using an onblur thing to check whether the value of the input is numeric, and if not, show an alert box to the user. I assume I would need to use getelementbyid. And on this page, there might be up to 30 similar input text fields, all of which need to be checked when the focus is lost. But...
