Hi,
I have a frame set. But people can still access the individual frame addresses without going throught the main frameset.

For example: instead of going to http://www.citizenerased.com and choosing 'Us' at the top, they can just go directly to http://www.citizenerased.com/pages/us.html

how can i prevent this?

Cheers

Add this to the <body> tag of all the frames to be displayed but not the page with the frameset:

<body onLoad="
var wl = top.window.location + '';
if(wl.indexOf('htm') >= 0)
window.location = 'http://www.citizenerased.com'">

With this code, if the page is accessed normally through a frameset, it will display, but if they type it into their browser URL, it redirects them to the main page with the frameset.

Small change to make it more frames-compatible.

<body onLoad="
var wl = parent.window.location + '';
if(wl.indexOf('htm') >= 0)
parent.window.location = 'http://www.citizenerased.com'">

If you already have some code in your <body> tag, you just need to add this to the <body> tag:

onLoad="var wl = parent.window.location + '';if(wl.indexOf('htm') >= 0) parent.window.location = 'http://www.citizenerased.com'"

This works nicely, change the body tags to

<body onload="(top.location != this.location)?true:document.location='http://www.citizenerased.com'">
