Firefox issues

[kss444]

I have the following JavaScript function that uses regexp to not allow typing of letters or special chars into a text box, the problem is that the users will also hve to use ctrl+C, ctrl+v the backspace key the F keys ect. these keys work fine in IE but in Firefox they do not work.

Can anyone help me out,
Thanks,

JS code:
function check_float(e, field) {
//alert(e.keyCode);

var key;
var code;

if (window.event) {
key = String.fromCharCode(e.keyCode);
code = e.keyCode;
}
else if (e.which) {
key = String.fromCharCode(e.which);
code = e.which;

}

if (key.match(/[~!@\+=\''#\""$%\{\}\[\]\\^&*()a-zA-Z]/i)) {
alert("Only digits, dashes and decimal points are allowed!");
return false;
} else {
//alert('key match');
}
}

I'm guessing (because you have not given the relevant code) that you're checking 'onkeypress', 'onkeyup', or 'onkeydown' rather than when focus is lost or the form is submitted.

This is bad because you will get an alert for every wrong key you press - how very, very, very, very annoying.

Why not simply check the field value once on blur/submit, and avoid the need to detect the values of each key pressed? I know I'd be much happier as a user of your site, and it'd keep your code a lot simpler.

Hope this helps,

Yes you are right, I was using key press, but I found an easier solution to use.
saveNMFCItemNumber.Attributes.Add("onblur", "this.value= this.value.replace(/[~!@\+=\''#\""$%\{\}\[\]\\^&*()a-zA-Z]/gi,'')")

Thanks though
