checking the entry

Hello....
I have a text box. The content of the text box should be only numeric value. what should i do if i want the user to be prompt a message box , whenever the input is non-numeric value?

Thanks

use client side vbscript or javascript. javascript is probably a better option as it works cross-browser.

you can use this if you want.

<script>
function checkInput(str)
{
var regex = /^\d$/g;
if(!regex.test(str))
{
alert('you can only have numeric values in this text box');
return false;
}
return true;
}
</script>

then in your form tag...

onsubmit=&quot;check(document.formname.elementname.value);&quot;

Thanks... but what i want is at the moment the user move from the text box to another text box, the message will be prompt out. it is like the change event in vbscript. is the any vbscript solution for this. can we use change event in asp same like in VB code?.

Thanks ....
