How Can I Close a Specific Browser Tab Using JavaScript?

Closing a Specific Tab in a Browser Window

For convenience and user-friendliness, you might want to set up a feature that allows users to close the current tab they're on without affecting other tabs in the same browser window. JavaScript's window.close() function comes in handy here.

To implement this feature:

1. Employ JavaScript's window.close() function. For example:

close();

Note: By default, this command closes the current tab. You can specify a different window if needed.

2. Utilize a confirmation dialog to seek user approval:

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

3. Incorporate the function into your HTML code:

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

Alternatively, you can use the following code:

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

Note: returning false here prevents the default event behavior and stops the browser from redirecting to a different URL.

The window.confirm() dialog will display "OK" and "Cancel" as its options. To customize it further, you can create a dedicated JavaScript dialog box.

Remember that browsers may handle window closures differently. For instance, Firefox restricts you from closing external windows, while IE may prompt the user for confirmation.
