Question

I am encountering a bug-like problem in Opera when trying the get the “closed” property of a popup window.

Here is the actions I performed.

>>> win = open('some url in the same domain with the parent window','name','feature')
Window 
>>> win.closed //at this point, the popup window is not closed
false
>>> win.closed //at this point, the pop window is closed
false //this should be true

The second “false” should be “true” as I may expect.

I ran it in Chrome and Firefox, it is all right.

Any clue?

PS:
I am using Opera 11.2, Linux

Answer 1

This works fine in my version of Opera, at least in the test case I put together here.

I can close the window by hand or with the button, and the closed property shows the correct value.

I am using Opera version 11.61 on linux.

Here is the code for the test case.

var popup = {};

function pop() {
    popup = window.open('foo', 'foo', "menubar=no,location=no,resizable=yes,scrollbars=yes,status=no,width=200,height=200" ); 
}    
function unpop() {
    popup.close();  
}
function check() {
    alert(({}).toString.call(popup) + ' closed: ' + popup.closed);
}

var b1 = document.body.appendChild(document.createElement('button'));
var b2 = document.body.appendChild(document.createElement('button'));
var b3 = document.body.appendChild(document.createElement('button'));

b1.textContent = 'open';
b2.textContent = 'close';
b3.textContent = 'check';

b1.onclick = pop;
b2.onclick = unpop;
b3.onclick = check;
