为什么FB.getLoginStatus在IE7中不起作用? [英] Why FB.getLoginStatus doesn't work in IE7?

问题描述

我正在将FB.getLoginStatus用于Facebook中的应用程序.这在包括IE8在内的所有浏览器中都可以正常工作.但是它不适用于IE7.我的代码是:

I am using FB.getLoginStatus for an application in Facebook. This works fine in all the browsers, including IE8. But it doesn't work for IE7. My code is:

       FB.getLoginStatus(function(response) {              
           if (response.session) {
              alert("logout");
            }
            else{
                FB.Event.subscribe('auth.login', function(response) {
                    login();
                });
              alert("login");
            }
        });

有人知道为什么吗?

推荐答案

根据 http://developers.facebook.com/docs/reference/javascript/fb.init/，正确的解决方案是在您的Web服务器上创建一个文件(例如channel.html)，其中仅包含:

According to the documentation at http://developers.facebook.com/docs/reference/javascript/fb.init/, the proper solution is to create a file on your web server (for instance channel.html) containing just:

 <script src="http://connect.facebook.net/en_US/all.js"></script>

然后在init选项中指定您的channel.html的绝对URL:

And then specifying the absolute URL to your channel.html in your init options:

 <div id="fb-root"></div>
 <script src="http://connect.facebook.net/en_US/all.js"></script>
 <script>
   FB.init({
     appId  : 'YOUR APP ID',
     channelUrl  : 'http://example.com/channel.html'  // custom channel
   });
 </script>

为了便于部署，我使用以下代码来计算channelUrl.

For convenience in deployment, I use the following to calculate my channelUrl.

 var curLoc = window.location;
 curLoc.protocol + "//" + curLoc.hostname + ":" + curLoc.port + "/channel.html"
