关闭选项卡Chrome/Safari浏览器-Javascript

我正在尝试使用javascript关闭Chrome/Safari浏览器选项卡。我尝试了下面所有的代码。但一切都不起作用

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

这是浏览器限制吗？

window.close不工作，因为它不知道关闭什么。请尝试此操作

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

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

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

如果您没有使用JavaScript创建它，则可能会重复，您无权关闭它。
