Browser listens for tab closing

Search for this question before and the answer is usually

window.onbeforeunload = function (e) {console.log('beforeunload')return 1;//Return whatever you want};

But when I use it myself, I refresh or click the x of the tag to close it, and the prompt will still not pop up. Later, I found that I need to interact with the current interface to realize the function of closing the tab for prompting.Even the simplest click of an interface counts as interaction.

Hehehehehehe...fuck!
