Javascript to automatically close a popup window
Question
I have the following code (listed below). In short, when a user clicks the button "All On" it will open a popup window with yahoo.com. I want the window to remain open for 3 seconds, then automatically close with no additional interaction from the user.
Although the popup opens exactly as desired, I get this error when the close attempts to execute.
script438: Object doesn't support property or method 'close' lights.html (11,31)
I am not a coder and cannot figure this out. Ultimately, this will primarily run on Safari iOS. And, obviously, the yahoo link will be replaced with a specific IP address. Thank you.

Give this a try
<script type="text/javascript">
function allOn(){
var win = window.open('http://www.yahoo.com','windowname','width=1,height=1,left=5,top=3');
setTimeout(function() { win.close();}, 3000);
}
</script>

win is a string.
Strings obviously don't have a close() method.
You want the Window object returned by open() .
