Javascript - 确认框以在用户单击退出按钮时重定向用户

Question

My objective is to when the user clicks on the exit button, it should appear a box with 2 buttons, to confirm or cancel the leave. After the confirm button is clicked, a redirect is needed.

I tried a lot of solutions, but I could only find a solution that I can control what happens after the confirm button.

But I need to do some action after they click on the confirm

My code:

window.onbeforeunload = function () {
   return "message"
}

That opens a box to confirm the exit, but I can't control the actions after it

Answer 1

something like this

  const result = confirm('Do this?');
    if(result){
      //redirect here
    }
