Its not too hard, they're using ASP and I'm not too familiar with it but I can tell you how to do it in PHP.
Basically what they do is upon change they read the POST info and select accordingly. So the dropdown would be somethign like this.
HTML Code:
<form method="POST" action="default.php">
<select name="background" onchange="this.submit()">
<option value="image.jpg">Image #1</option>
<option value="image2.jpg">Image #2</option>
</select>
And on the default.php page have this code:
PHP Code:
if (isset($_POST['background']))
{
$bg_img = $_POST['background'];
}
else
{
$bg_img = 'default.jpg';
}
And wherever you set the background, like if you were to set it on the body tag you'd make the tag this:
HTML Code:
<body background="<?php echo $bg_img ?>">
My javascript on the dropdown may be incorrect but you can find out online. Hope this helps  |
