Close Tab Chrome/Safari Browser - Javascript

Question

I am trying to close Chrome/Safari browser tab using javascript. I tried all the below code. But nothing is working.

open('about:blank', '_self').close(); - This opens up a new tab, and the user is able to browse back. Which is not required.
open(location, '_self').close(); - Scripts may close only the windows that were opened by it.
window.open('','_parent','');
window.close(); - Not working

Is it a browser restriction?

Answer 1

The window.close doesn't work because it doesn't know what to close try this

//Global var to store a reference to the opened window
var openedWindow;

function openWindow() {
  openedWindow = window.open('moreinfo.htm');
}

function closeOpenedWindow() {
  openedWindow.close();
}
