Javasscript method to allow numeric only entry

[WIREMESH]

In my asp.net 2.0 vb application I have several textboxes that are used to enter numeric data.

Is there a javascript function I can use to prevent the entry of non numeric data for specific textboxes?

I would prefer the function ignore non numeric characters as they are entering the text into the control? Worst case, if they did enter non numeric characters, the control would blank out the field after the control loses focus.

use regular expression validator and use the expression as ^[0-9]+$

your solution is not a javascript function that filters the keystrokes as they are entered

If you want a javascript function, then post in the javascript forum.
