Prompt User before browser close?
- by JM4
We have an administrative portal that our teachers constantly forget to download their latest PDF instructions before logging out and/or closing the browser window. I have looked around but can't find what I'm looking for.
I want to accomplish the following goals:
Goal 1
Before a user can close the browser window, they are prompted "Did you remember to download your form?" with two options, yes/no. If yes, close, if no, return to page.
Goal 2
Before a user can click the 'logout' button, they are prompted with the same as above.
My first pass at the very basic code (which does not work for browser close) is:
<!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>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script type="text/javascript">
function init()
{
if(window.addEventListener)
{
window.addEventListener("beforeunload", unloadMess, false);
}
else if(window.onbeforeunload)
{
window.onbeforeunload = unloadMess;
};
}
function unloadMess()
{
var User_Message = "[Your user message here]"
return User_Message;
}
</script>
</head>
<body onload="init();">
hello this is my site
</body>
</html>
anybody ever come across a good solution?
