Keypress event

I want to return keycode 0 when the user enters anything else than a number in a textbox.

I have made a eventhandler, I check the keycode or the which if the navigator is a netscape.

If the ascii code is anything else than a number I set the keycode = 0 in IE, and the which in netscape = 0. This works in IE, why not in Netscape???

Help needed...

Hi Smirre

I usually just do it on the OnBlur event of the text field !

here's my function

Code:

---

                function isNum(txt){
                        if (isNaN(txt.value)){               
                                alert('Numbers only!');
                                txt.focus();
                                txt.select();
                                }
                }

---

usage:
onBlur="isNum(this);"
