Close javascript-popup-window from anywhere

Question

I\'m trying to build a popup that can be closed from anywhere.

On the Mainpage you have the option to open it. At any point while browsing the mainpage the user shall be

Answer 1

There are three solutions I propose depending on what the problem actually is.

1) closepopup() does not work on other pages

If you need to close the popup from page B when it was opened from page A the following code will allow you to obtain a reference to the popup from page B and close it. Reference: Find window previously opened by window.open

PageA.html

Open window...

Go to Page B

PageB.html

Close window...

2) closepopup() does not work on the same page as window is opened

A global reference to my_window is needed so you would need to change the code like this:

     var my_window; //global reference here
    function popuponclick()
       {
          my_window = window.open("", "mywindow","status=1,width=350,height=150");
       }

       function closepopup()
       {
          my_window.close ();
       }

3) Final third solution using frames

You separate your page into 1 frames (one which is 100%) and another that is 0%.

You add the window open/close code in the parent frame. Than you call the window control code via cross frame javascript commands.

Frames HTML Containing Javascript

Internal Frame (frame.html) - calling parent Javascript

 Open Window 

 Close Window 

 Refresh Frame (and try again)
