javascript confirm dialog box before close browser window
提问by user881851
I need to display a confirm dialog box before closing the browser window using javascript or PHP. The confirm box should come up when I click the close button of browser; otherwise, the dialog should not be displayed.
我需要在使用 javascript 或 PHP 关闭浏览器窗口之前显示一个确认对话框。当我点击浏览器的关闭按钮时,确认框应该出现;否则,不应显示该对话框。
Thanks
谢谢

This will display it when closing the browser:
这将在关闭浏览器时显示:
window.onbeforeunload = function (event) {
var message = 'Sure you want to leave?';
if (typeof event == 'undefined') {
event = window.event;
}
if (event) {
event.returnValue = message;
}
return message;
}

With Jquery:
使用jQuery:
$(window).bind('beforeunload', function(e) {
// Your code and validation
if (confirm) {
return "Are you sure?";
}
});
