How can I close the current tab using JavaScript?

I want to create a link on a webpage that will close the active browser tab, without affecting the other open tabs.

When the user clicks the close link, I want an alert to appear asking for confirmation with two options: “YES” and “NO.”

  • If the user clicks “YES,” the tab should close.
  • If the user clicks “NO,” nothing should happen.

How can I implement this using JavaScript close tab functionality?

Any suggestions or code examples?

If you’re looking for a quick way to let users confirm before closing a tab, you can use the native confirm() along with window.close():

javascript

CopyEdit

function closeTab() {
  if (confirm("Do you want to close this tab?")) {
    window.close();
  }
}

Just hook that up to a button or link like this:

<a href="#" onclick="closeTab()">Close Tab</a>

:bulb: Heads up: window.close() typically only works if the tab was originally opened via JavaScript (like using window.open). If the user opened the tab manually, most browsers will block the close action for security reasons. So it’s handy in specific cases, but not guaranteed everywhere.

hey @mehta_tvara if you want more control than the default confirm() popup? You can create your own custom YES/NO modal for a smoother UX:

<button onclick="showConfirm()">Close Tab</button>

<div id="confirmBox" style="display:none; border: 1px solid #ccc; padding: 20px; background: #f9f9f9;">
  <p>Close this tab?</p>
  <button onclick="window.close()">YES</button>
  <button onclick="hideConfirm()">NO</button>
</div>

<script>
function showConfirm() {
  document.getElementById("confirmBox").style.display = "block";
}
function hideConfirm() {
  document.getElementById("confirmBox").style.display = "none";
}
</script>

This gives you full styling control and feels more like a natural part of your app flow.

Just remember: window.close() is still subject to browser restrictions; it usually only works if the tab was opened with JavaScript (via window.open).

Having been in the industry for almost 4 years, I can say that most browsers won’t allow window.close() unless the tab was opened via script—but there’s a handy workaround for that.

<a href="#" onclick="confirmClose()">Exit</a>

<script>
function confirmClose() {
  if (confirm("Are you sure you want to close this tab?")) {
    const tab = window.open('', '_self'); // reopens the same tab
    tab.close(); // then tries to close it
  }
}
</script>

What’s happening here? window.open('', '_self') basically reopens a reference to the current tab, which sometimes satisfies the browser’s rules enough to allow tab.close() to work.

It’s not guaranteed to work everywhere, but it gives you a better shot compared to calling window.close() directly.

Hope this helps: :slight_smile:
