Question

I know that in Javascript, I can call the function self.close() to close my current window.
I was wondering what if rather than closing the window I wanted to alert “foo”, is that possible?

which in this case my code would look like

   function funky(){
alert("foo");
}

can I do this in my html

self.funky()

To invoke funky? In other words I want to alert my user a message before they close the browser

The global property “self” is just an alias for window (in some browsers). Thus any property of window can be accessed via “self” too.

If you declare a global function, then it too becomes a property of “self”/window.
