Question

I have a JS that opens a new tab. And I want to refresh the original window but only once the opened tab is closed. How would you do it?

Here’s the code I have now (which obviously doesn’t work – it does the refresh immediately after opening the new window):

window.open( SOME_WINDOW );
window.location.reload();

Answer 1

You can do it with something like this. Store the window handle, and use a polling timer to check the closed property of the window.

var childwindow = window.open(SOME_WINDOW); 
var timer = setInterval(function() {   
  if(childwindow.closed) {  
    clearInterval(timer);  
    window.location.reload();
  }  
}, 1000);
