beforeunload事件非常严格。在IE / Edge中，您所能做的就是通过从事件处理程序返回自定义消息来显示它。在Firefox和Chrome中，您甚至无法做到这一点 - 您返回的任何自定义消息都将被忽略，浏览器将显示其标准数据可能丢失消息。



您当然无法打开窗口或显示模态对话框。如果可以的话，互联网上的每个恶意网站都会阻止您离开页面。



坚持从事件处理程序返回一个简单的字符串。允许它的浏览器将显示您的消息，而不显示消息的浏览器将显示标准消息。

$(document).ready(function(){
var myEvent = window.attachEvent || window.addEventListener;
var chkevent = window.attachEvent ? '' : 'beforeunload'; /// make IE7, IE8 compitable

myEvent(chkevent, function(e) { // For >=IE7, Chrome, Firefox
var confirmationMessage = $('#myModal').modal('show'); // a space
(e || window.event).returnValue = confirmationMessage;
return confirmationMessage;
});
});

What I have tried:

i want to first confirmation, and when i click stay on page then will come model but it not working properly in mozilla what happen both are come same time model and confirmation in mozilla and it working in chrome plz help me..

('#myModal').modal('show'); // a space

The "beforeunload" event is very restrictive. In IE / Edge, all you can do is display a custom message by returning it from the event handler. In Firefox and Chrome, you can't even do that - any custom message you return will be ignored, and the browser will display its standard "data may be lost" message instead.

You certainly can't open windows or display modal dialogs. If you could, every malicious site on the Internet would do it to prevent you from leaving the page.

Stick with returning a simple string from your event handler. Browsers which allow it will display your message, and those that don't will display a standard message instead.
