Answer / kevin konkle
//Have this be called off the keypress event of your
textbox control.
function numberFormat(fld, e)
{
var key = '';
//This string contains all characters you want to allow
var strCheck = '0123456789';
var whichCode = (window.Event) ? e.which : e.keyCode;
if (whichCode == 13) return true; // Enter
if (whichCode == 8) return true; // Delete
// Get key value from key code
key = String.fromCharCode(whichCode);
// Not a valid key
if (strCheck.indexOf(key) == -1) return false;
//If it is a legal value then add it to the text box
fld.value += key;
return false;
