I have a task to add an alert banner to a SharePoint 2007 site that would prompt a user to accept a disclaimer before they are allowed into a site. What would be the best way to accomplish this?

The phase2 examples does not work. The logic is what I am looking for but the code is buggy and does not work. Were you able to make it work?

Be sure to delete your browser cache and close the browser/reopen it.  

Also, sometimes when you copy paste code in, it reformats the apostrophes into quotes (so be sure to check that)
<script type=”text/javascript” language=”javascript”>

var agreement = GetCookie();

//checks for cookie and displays disclaimer alert if new user

if(agreement==''){

var decision = confirm('DISCLAIMER or Message GOES HERE');

if(decision == true){

//writes a cookie

var expiredays = 365;

var exdate=new Date()

exdate.setDate(exdate.getDate()+expiredays)

document.cookie='cookiename'+ '=' +escape('Agree To Disclaimer')+

((expiredays==null) ? '' : '; expires='+exdate.toGMTString())

}

else{

location.href='/_layouts/SignOut.aspx';

}

}

//gets the Cookie if it exists

function GetCookie(){

if (document.cookie.length>0){

c_name = 'cookiename';

c_start=document.cookie.indexOf(c_name + '=')

if (c_start!=-1)

{

c_start=c_start + c_name.length+1

c_end=document.cookie.indexOf(';',c_start)

if (c_end==-1) c_end=document.cookie.length

return agreement = unescape(document.cookie.substring(c_start,c_end))

}

}

return '';

}

</script>

Open in new window

Tehzar,
The code you provided works perfectly. The only piece left is how to make the cookie expire after the browser close. The current expiration is set for 365. After reading a few blogs I found a few entries that said leave the expire date blank and it will expire when the browser is closed.

When I tried to mod the code to leave expire date blank it does not create a cookie for the current session. I would like the cookie to exist only for the current session and any pages accessed during that session.  Currently the popup keep repeating every time I leave the homepage and come back within the active session. The cookie should be good for the active session only and re-prompt the user to accept the disclaimer when he or she returns to the page.

Thank you for your response.
