I have a html form which then pipes to a phpmail script to mail the information to myself, I would like to add some form of verification to ensure a user cannot just send a blank form.
Each field has a 'default' value which I think i could probably use to set a kind of check up such as if $blah == "default value here" die kind of effect..
I was about to sign up to .mac (www.mac.com) on my PC but when I went to free trial, it informed me that to get the trial, I would have to sign up using a Mac. I do have a Mac but I was wondering whether anybody could help me with the script for that.
What I would like is for someone on a PC to go to my site, and be given a customised message informing them that they can only browse the site using a Mac. I don't want a redirect, just something like the .mac system, but when somebody access's it on a Mac then the site will be displayed without a problem.
I'm making a contest for a movie site and they want me to add age verification via a javascript call that will pop up a window if the user is under 18. I absolutely no clue where to start on this.

I believe I have any digit 0-9 one or more times and negating decimals. but for some reason it allows decimals and letters. also is it correct to put return true or can i just leave it blank?

I keep getting an error that says item is null. I'm a little lost because once I got my regExp to start working this actually worked for a little bit. When I came back I was getting an error.
var creditExp = /^([345])(\d{3})\-?(\d{4})\-?(\d{4})\-?(\d{4})$/;
var creditNumber = document.getElementById("creditnum").value;
var item = creditExp.exec(creditNumber);
document.getElementById("creditnum").value = item[1] + item[2] + "-" + item[3] + "-" + item[4] + "-" + item[5];
if (item[1] == 4 && document.getElementById("card1").checked == true) {
return true;
}else
if (item[1] == 5 && document.getElementById("card2").checked == true) {
return true;
}else
if (item[1] == 3 && document.getElementById("card3").checked == true) {
return true;
} else {
alert("You must enter a valid credit card number.");
document.getElementById("creditnum").focus();
return false;
}
var billingName = document.getElementById('creditname').value;
if (billingName == null || billingName == "") {
alert("You must enter your first name as printed on your credit card!");
document.getElementById('creditname').focus();
return false;

I'm a front-end designer trying to get a javascript email verification script (highlighted below in blue) to work properly in IE7, Safari and Firefox.
In my html layout (posted below) I have a call to the javascript. The form works in IE7 and Safari but fails to perform form verification in Firefox.
A weird note, the form verification works if I place the javascript call before the DOCTYPE declaration in the html.
Here is my html code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

I'm using jquery-validation for validation of an edit form. The behaviour of the onBlur validation is a bit strange.
I've put an example up on my webserver here: [URL]
It's using a patched version of jQuery Validation with some additional console debug output. Works in Chrome and Firebug.
This patch for version 1.9.0 fixes the problem, but I'm not sure of there are other dependencies I haven't considered.

I have a signup form on my site..when the user clicks the signup button, I am using a little script to check the form and make sure it's filled out correctly. I know i'm calling the script right because I did some error checking/debugging but it isn't actually doing its job.
Further more, I tried a quick alert to see the value of my variable, returned and I get an alert that reads "[object nodes list]".
Here's my script
<head>
<script type="text/javascript">
function chk_Empty(){
alert("working");
