单击浏览器刷新按钮时的Ajax调用 [英] Ajax call when click on Browser refresh Button

问题描述

我在Ajax深度链接方面苦苦挣扎，想知道当用户单击浏览器刷新"按钮时是否可以进行Ajax调用.

Im struggling with Ajax Deep linking and wonder if is possible to make an Ajax call when user click on Browser refresh button.

我尝试使用 beforeunload 可行，但是在ajax调用之后仍然向服务器发出请求?有没有办法阻止对服务器的请求?

I tried to use beforeunload It works but still make a request to the server after the ajax call Is there a way to prevent the request to the server ?

    $(window).on('beforeunload',function(e){
        //ajax call here.          
    });

推荐答案

了解用户单击刷新的时间是不容易的.从浏览器的角度来看，他们只是在离开页面浏览.您可以使用onbeforeunload方法进行操作...

There is no hook into knowing when a user clicks refresh. From a browser perspective they are simply navigating away from the page. You could hook into the onbeforeunload method to do something...

window.onbeforeunload = function(){ return 'Testing...' }
