So effectively, it cannot close the tab if it would cause window to closes by being the last tab open.įirefox has an advanced setting that you can enable to allow scripts to close windows, effectively enabling the window.close() method. Note: This solution can only close the tab if it is NOT the last tab open however.
Var confirm_result = confirm("Are you sure you want to quit?") By using the Chrome plugin TamperMonkey however we can use the window.close() method if you include the // window.close in the UserScript header of TamperMonkey.įor example, my script (which is triggered when a button with id = 'close_page' is clicked and if 'yes' is pressed on the browser popup) looks like: // =UserScript=
Window.close() will work on tabs opened by a script, or by an anchor with target="_blank" (opened in a new tab)īrowser Specific work-arounds: Google Chrome:Ĭhrome does not allow the window.close() script to be to be run and nothing happens if you try to use it. However, most modern browsers no longer support this script, potentially for security reasons. In the past, the jQuery script window.close() was able to close the current tab without a problem on most browsers. Note: These workarounds were done with a locally hosted site in mind, and (with the exception of Edge) require the browser to be specifically configured, so would not be ideal for publicly hosted sites. Sorry for necroposting this, but I recently implemented a locally hosted site that had needed the ability to close the current browser tab and found some interesting workarounds that are not well documented anywhere I could find, so took it on myself to do so. It may still be possible in IE (at least pre-Edge). If you click on this the window will be closed after 1000msĪs far as I can tell, it no longer is possible in Chrome or FireFox. I believe IE will ask the user for confirmation. Firefox disallows you from closing other windows. If you opened the window with Javascript (via window.open()) then you are allowed to close the window with javascript. Note: there is browser-specific differences with the above. If you really want Yes and No you'll need to create some kind of modal Javascript dialog box. Now the options on the nfirm() dialog box will be OK and Cancel (not Yes and No). Otherwise the browser will attempt to go to that URL (which it obviously isn't).
You return false here to prevent the default behavior for the event.
If you found this tutorial helpful then don't forget to share.You will need Javascript to do this. Return 'Are you really want to perform the action?' Īs I said at the start of this tutorial, you cannot fully control the web page because you are not the owner of the Browser, you can only access limited info.įor example, you can only catch when the tab is closing but you don’t get any information why is closing.īut somehow it’s better to show a confirm box that asks the question to the user and this gives a chance to get back if the action is performed mistakenly. You can use this to display an alert message on the Browser for this you only need to return your message text. Onbeforeunload event trigger when tries to close, refresh the tab or closing the Browser.
