How to focus on a pop-up every 1 minute?

Question

How to focus on a pop-up every 1 minute? Remembering that the pop-up is minimized and I want to leave it "in evidence" on the user screen.

Answer 1

The way to do this is with the function focus of the object window returned by window opening.

For example:

var janela = window.open('http://www.google.com');
setInterval(function() { 
    janela.focus();
}, 60000);

The problem is that this does not seem to work in several browsers, after all they want to prevent malicious scripts from focusing the user on a particular window, such as an advertisement, for example.

Tests carried out:

• Chrome: not working (no errors)
• Firefox: did not work (no errors) and popup opened a new tab
• Internet Explorer: it worked

Therefore, my suggestion is to avoid the use of popup. First because often this is an attempt to replicate desktop program functionality in web applications. Second because I always see this causing many side effects and bumping into several limitations, such as the case of Firefox, which opened the popup in a new tab.

Think of an alternative solution, like the notifications here from Stackoverflow or Facebook, for example.

Update

I tested an alternative, reopening the popup in the given interval:

setInterval(function() { 
    window.open('http://www.google.com', 'minha_janela').focus();
}, 60000);

However, the result is the same in the various browsers, that is, only IE gives the focus back to the popup. The difference is that the page is updated at each opening and, if the popup has been closed, it is reopened.

Answer 2

var p = window.open("about:blank", "_blank", "width=610,height=610");
p.location = "http://www.google.com";

setInterval(function(){
    p.focus();
}, 60000);

Make the call from var p before anything else in your routine to prevent you from falling into the pop-up blocker.
