Simple Javascript Problem
Here goes again. This time, working with JavaScript. Here's my problem:
I have my site, right. I have a mobile version, and a desktop version. I know it isn't very common, but I
am putting a css/javascript popup which asks the iPad user which version he/she would like to use. Here is my HTML code:
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">
<head>
<script type="text/javascript" src="csspopup.js"></script>
<script type="text/javascript" language="javascript">
if((navigator.userAgent.match(/iPad/i))) {
popup('popUpDiv');
}
-->
</script>
<style type="text/css">
<!--
#blanket {
background-color:#111;
opacity: 0.65;
position:absolute;
z-index: 9001; /*ooveeerrrr nine thoussaaaannnd*/
top:0px;
left:0px;
width:100%;
display:none;
}
#popUpDiv {
position:relative;
background-color:#eeeeee;
width:30%;
height:20%;
z-index: 9002; /*ooveeerrrr nine thoussaaaannnd*/
padding:15px 15px 15px 15px;
display:none;
}
-->
</style>
<!--[if gte IE 5]> <style type="text/css"> #blanket {filter:alpha(opacity=65);}</style><![endif]-->
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" href="style.css" media="screen" />
<title>Test Site</title>
</head>
<body>
<div id="blanket"></div>
<div id="popUpDiv"> You are on a wonderful device made by Apple called the iPad. I cannot tell which iPad, but I know you are on one. My question is: Would you like to view the <a href="mobilesite">Mobile Site</a> or the <a href="desktopsite">Desktop Site</a>?
</div>
<a href="#" onclick="popup('popUpDiv')">Click Here To Open The Pop Up</a>
</body>
</html>
And here is my JavaScript:
Code:
function toggle(div_id) {
var el = document.getElementById(div_id);
if ( el.style.display == 'none' ) { el.style.display = 'block';}
else {el.style.display = 'none';}
}
function blanket_size(popUpDivVar) {
if (typeof window.innerWidth != 'undefined') {
viewportheight = window.innerHeight;
} else {
viewportheight = document.documentElement.clientHeight;
}
if ((viewportheight > document.body.parentNode.scrollHeight) && (viewportheight > document.body.parentNode.clientHeight)) {
blanket_height = viewportheight;
} else {
if (document.body.parentNode.clientHeight > document.body.parentNode.scrollHeight) {
blanket_height = document.body.parentNode.clientHeight;
} else {
blanket_height = document.body.parentNode.scrollHeight;
}
}
var blanket = document.getElementById('blanket');
blanket.style.height = blanket_height + 'px';
var popUpDiv = document.getElementById(popUpDivVar);
popUpDiv_height=blanket_height/2-150;//150 is half popup's height
popUpDiv.style.top = popUpDiv_height + 'px';
}
function window_pos(popUpDivVar) {
if (typeof window.innerWidth != 'undefined') {
viewportwidth = window.innerHeight;
} else {
viewportwidth = document.documentElement.clientHeight;
}
if ((viewportwidth > document.body.parentNode.scrollWidth) && (viewportwidth > document.body.parentNode.clientWidth)) {
window_width = viewportwidth;
} else {
if (document.body.parentNode.clientWidth > document.body.parentNode.scrollWidth) {
window_width = document.body.parentNode.clientWidth;
} else {
window_width = document.body.parentNode.scrollWidth;
}
}
var popUpDiv = document.getElementById(popUpDivVar);
window_width=window_width/2-150;//150 is half popup's width
popUpDiv.style.left = window_width + 'px';
}
function popup(windowname) {
blanket_size(windowname);
window_pos(windowname);
toggle('blanket');
toggle(windowname);
}
This isn't my popup code, got it from a guy named Pat Burt.
As you can see in the HTML code:
HTML Code:
<script type="text/javascript" language="javascript">
if((navigator.userAgent.match(/iPad/i))) {
popup('popUpDiv');
}
-->
</script>
Now why won't it work? I used the same format, and everything. Any help is appreciated. Note: the css file only includes a background image.
Thanks,
Treyton
