Random Popup Windows

This script lets you create a series of random popup windows.

A random URL is selected and displayed on page load, or when the page is refreshed.

Compatability

Should work OK in all browsers - no problems with IE 5 or NS 6.1.

Paste the following code in your head section of your page:

<script >  </script>

And add this to your body tag:

<body onload="randompopup()">

How It Works

The desired number of URLs are placed in an array, newurl:

var newurl=new Array()

newurl[0]="url 1"
newurl[1]="url 2"
newurl[2]="url 3"
newurl[3]="url 4"
newurl[4]="url 5"

The URLs can be local pages on your site - eg: mypage.html

Or links to other sites - eg: http://www.yahoo.com.

You can have as many URLs as you like - just add extra array items at the bottom.

The function randompopup() is called on page load:

var mylocation=newurl[Math.floor(Math.random()*newurl.length)]

This randomly chooses a number whose limits are the length of the array, newurl.length.

In this example, there are 5 URLs, hence the numbers possible are 0, 1, 2, 3 and 4.

The URL whose number is selected is then assigned to the variable mylocation.

For example, if 3 is selected:

mylocation=newurl[3]

Referring to the script section above, you'll see that the contents of newurl[3] is URL 4.

This value is now passed to the popup generator section:

a customised popup window is created
the chosen URL is loaded into the popup

For details of how to create customisable popup windows, see Creating A Popup Window.

Try It Out

Refresh this page a few times.

You'll see that the contents of the popup change each time.
