How Can I Close the Current Browser Tab with JavaScript Confirmation?

Closing the Current Tab in a Browser Window

Problem:

Many users encounter the need to close the active tab in a browser without interrupting or closing other open tabs. Additionally, there is a preference for a confirmation message to be displayed before closing the tab.

Solution:

To achieve this, JavaScript is employed, particularly the window.close() function:

close();

It is important to note that in this context, "close" implies the current tab. The following code is equivalent:

window.close();

Furthermore, it is possible to target a specific window. For instance:

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

To incorporate this functionality into HTML, the following snippet can be used:

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

Alternatively, the following code can be employed to prevent the default behavior of the event:

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

Initially, the window.confirm() dialog box displays "OK" and "Cancel" options instead of "Yes" and "No." To address this, a custom modal JavaScript dialog box may need to be created.

Browser Compatibility Considerations:

Browser behaviors vary regarding this functionality. For example, Firefox restricts the closing of windows that were not opened using JavaScript. Internet Explorer may prompt the user for confirmation, while other browsers may have different approaches.
