如何在浏览器窗口中关闭当前选项卡? [英] How to close current tab in a browser window?

问题描述

I want to create a link on a webpage that would close the currently active tab in a browser without closing other tabs in the browser.
When the user clicks the close link, an alert message should appear asking the user to confirm with two buttons, "YES" and "NO". If the user clicks "YES", close that page and If "NO", do nothing.

How can it be done? Any suggestions?

解决方案

You will need Javascript to do this. Use window.close():

close();

Note: the current tab is implied. This is equivalent:

window.close();

or you can specify a different window.

So:

function close_window() {
  if (confirm("Close Window?")) {
    close();
  }
}

with HTML:

<a href="javascript:close_window();">close</a>

or:

<a href="#" onclick="close_window();return false;">close</a>

You return false here to prevent the default behavior for the event. Otherwise the browser will attempt to go to that URL (which it obviously isn't).

Now the options on the window.confirm() dialog box will be OK and Cancel (not Yes and No). If you really want Yes and No you'll need to create some kind of modal Javascript dialog box.

Note: there is browser-specific differences with the above. If you opened the window with Javascript (via window.open()) then you are allowed to close the window with javascript. Firefox disallows you from closing other windows. I believe IE will ask the user for confirmation. Other browsers may vary.
