How to open new window from parent window, then later close when parent window loads specific page?

Question

Note: I can only do this using JavaScript in the IE11 developer's console.

On my parent window (www.mysite.com/1.html), there's a link on the page that opens a new page in a separate window (www.mysite.com/9.html).

In mysite.com/1.html (parent?), I need to click on (or open) that link to mysite.com/9.html (child?) as a separate window. Then from the parent window, I need to go to mysite.com/2.html. Then, in the same parent window, I need to go to mysite.com/3.html.

Now, when my parent window reaches mysite.com/3.html, I need to somehow close the child window (or close all windows that are not the parent).

How can I do this by calling a function in the parent window?

I'm aware that variables are reset/destroyed when a new page is loaded in a window. But is there a way I can take advantage of cookies to my parent window remember: "oh yeah! I opened 9.html a while back. I even gave/assigned it a name! Time to close it."

Answer 1

Open your windows through javascript so that you are able to call window.close() on them. Look at this example http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_win_close2

<script>
var myWindow;

function openWin() {
    myWindow = window.open("http://www.w3schools.com", "_blank", "width=500, height=500");
}

function closeWin() {
    myWindow.close();
}
</script>

To close the child when the parent is refreshed, add this code in your script

function closeIt()
{
  myWindow.close();
}
window.onbeforeunload = closeIt;
