Capture Key, only allow numbers

[Leroy]

I have this function:

function ValidateIntKey( )
{
var Key;
var CharKey;
Key = event.keyCode;
alert(Key);

//CharKey = String.charCode At(Key);
alert(String.fr omCharCode(Key) );
CharKey = String.fromChar Code(Key)
if (!isInteger(Cha rKey))
{
alert("no integer");
}
}

Where i have "alert("no integer");" i want to make the keyCode null so
that it doesn't reach the textbox this function is attached to. How
do i do this? I tried:

event.keyCode = 0; but this did not work. Any other ideas?

Has it occurred to you that this function is going to annoy the crap out of
everyone? We all make typing mistakes from time to time; that's why
keyboards have a delete key. If your web page throws an alert at me every
time I make a tiny slip of the finger then I'm not going to stay there very
long.

Why not do your form validation the old-fashioned way and check for integers
in an onsubmit() event?

Absolutely! Even if you do away with the alert and simply block
all non-integer keystrokes, you're going to send people away angry.

Imagine that I'm trying to type "123" and accidentally hit "12w".
I may not even be looking at the screen when I realize that I've
hit the wrong key and automatically hit the backspace. If you've
blocked the "w" keystroke, I've just deleted the "2".

Re: Capture Key, only allow numbers



I am not looking for an analysis of what i am doing. I am just looking
for an answer to my problem, please.

I understand what everyone is saying about the annoyance, but i have a
reason for doing this and it is not relevant to getting an answer to my
problem.

Can someone please tell me how i can intercept a keystroke an replace it
with nothing? Thank you in advance

Found the answer.

function ValidateIntKey( )
{
var Key;
var CharKey;
Key = event.keyCode;
//alert(String.fr omCharCode(Key) );
CharKey = String.fromChar Code(Key)
if (!isInteger(Cha rKey))
{
event.returnVal ue = false;
}
}

CharKey = String.fromChar Code(Key)
if (!isInteger(Cha rKey))
{

}
}

This only works on keypress, not keyup or keydown.

This is a feature of IE. When you do the alert, IE looses track of what
key was pressed.

Your problem is that you have not pressed the Power button
of the computer you are abusing. You're welcome.

And to think it only took you 13 days to come up with that garbage. Wow.
You are starting to really impress me. Wanna buy some Ocean Front
property in Arizona? I have a deal just for you........

P.S. ExLax might be of help to you, since you are full of s**t.
