推荐答案

您无法使用VB. VB和ASP.Net在服务器端运行，因此无法得知客户端已关闭其浏览器.您可以使用javascript中的window.close()事件在客户端执行一些操作.

You can''t with VB. VB and ASP.Net run on the server side so it has no way of knowing that a client has closed its browser. You can do some things on client side using the window.close() event in javascript.

// wire up event to fire when closing window
window.onbeforeunload = WindowIsClosing;

function WindowIsClosing() {
  if (window.event.clientX < 0 || window.event.clientY < 0) {
// do your own logic, but for example:
        if (!Validate()) {
            var msg = 'Test';
            event.returnValue = msg;
            return msg;
        }
    }
}
