但是如何在SPA的视野中做呢 它不包含html或body标记,只包含div
我在单页应用程序中使用durandal

我将脚本添加到app.js中

   initializeFB: function () {
        if (!isFBInitialized.isInitialized) {

            FB.init({
                appId: 'xxxxxxxxxxxx',
                appSecret: 'xxxxxxxxxxxxxxx',
                // App ID from the app dashboard
                channelUrl: '//mysite//channel.html', // Channel file for x-domain comms
                status: true,                                 // Check Facebook Login status
                cookie: true, // enable cookies to allow the server to access the session
                xfbml: true                                  // Look for social XFBML plugins on the page to be parsed
            });



            (function (d, s, id) {
                var js, fjs = d.getElementsByTagName(s)[0];
                if (d.getElementById(id)) { return; }
                js = d.createElement(s); js.id = id;
                js.src = "//connect.facebook.net/en_US/all.js";
                fjs.parentNode.insertBefore(js, fjs);
            }(document, 'script', 'facebook-jssdk'));

            // Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
            // for any auth related change, such as login, logout or session refresh. This means that
            // whenever someone who was previously logged out tries to log in again, the correct case below 
            // will be handled. 
            FB.Event.subscribe('auth.authResponseChange', function (response) {
                // Here we specify what we do with the response anytime this event occurs. 
                if (response.status === 'connected') {
                    // The response object is returned with a status field that lets the app know the current
                    // login status of the person. In this case, we're handling the situation where they 
                    // have logged in to the app.
                    testFBAPI();
                } else if (response.status === 'not_authorized') {
                    // In this case, the person is logged into Facebook, but not into the app, so we call
                    // FB.login() to prompt them to do so. 
                    // In real-life usage, you wouldn't want to immediately prompt someone to login 
                    // like this, for two reasons:
                    // (1) JavaScript created popup windows are blocked by most browsers unless they 
                    // result from direct user interaction (such as a mouse click)
                    // (2) it is a bad experience to be continually prompted to login upon page load.
                    FB.login();
                } else {
                    // In this case, the person is not logged into Facebook, so we call the login() 
                    // function to prompt them to do so. Note that at this stage there is no indication
                    // of whether they are logged into the app. If they aren't then they'll see the Login
                    // dialog right after they log in to Facebook. 
                    // The same caveats as above apply to the FB.login() call here.
                    FB.login();
                }
            });

            isFBInitialized.isInitialized = true;
        }
    },
并在viewattached中调用它 作为


然后它会很好地工作,但也许它会帮助一些人。对我来说,在一个单页应用程序上呈现独特的fb注释的关键是
fb.XFBML.parse()

每次我要呈现唯一的注释时:

  • 更改url,每个fb评论线程都被分配到特定的url 因此,我可能有www.someurl.com/#123、www.someurl.com/#456、www.someurl.com/#789,每个都有自己的fb评论线程。在AngularJs中,这可以通过
    $location.hash('123')完成

  • 创建一个新的fb comments div,其中“number”等于“123”、“456”或“789”

    
    

  • 调用执行fb SDK的函数

    function FBfun(path) {
      setTimeout(function() { // I'm executing this just slightly after step 2 completes
        window.fbAsyncInit = function() {
          FB.init({
            appId : '123456789123',
            xfbml      : true,
            version    : 'v2.2'
          });
        };
    
        (function(d, s, id){
          var js, fjs = d.getElementsByTagName(s)[0];
          if (d.getElementById(id)) {return;}
          js = d.createElement(s); js.id = id;
          js.src = "//connect.facebook.net/en_US/sdk.js";
          fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));
    
        FB.XFBML.parse(); // This is key for all this to work!
      }, 100);
    }
    

  • 步骤3:让我的React应用程序变得更为友好(更为林特友好):

    只需添加
    FB.XFBML.parse()
    
    function FBfun(path) {
      setTimeout(function() { // I'm executing this just slightly after step 2 completes
        window.fbAsyncInit = function() {
          FB.init({
            appId : '123456789123',
            xfbml      : true,
            version    : 'v2.2'
          });
        };
    
        (function(d, s, id){
          var js, fjs = d.getElementsByTagName(s)[0];
          if (d.getElementById(id)) {return;}
          js = d.createElement(s); js.id = id;
          js.src = "//connect.facebook.net/en_US/sdk.js";
          fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));
    
        FB.XFBML.parse(); // This is key for all this to work!
      }, 100);
    }
    
    componentDidMount() {
        window.fbAsyncInit = () => {
            window.FB.init({
                appId: '572831199822299',
                xfbml: true,
                version: 'v4.0',
            });
        };
    
        (function (d, s, id) {
            const fjs = d.getElementsByTagName(s)[0];
            if (d.getElementById(id)) { return; }
            const js = d.createElement(s);
            js.id = id;
            js.src = '//connect.facebook.net/ru_RU/sdk.js';
            fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));
    
        setTimeout(() => {
            window.FB.XFBML.parse();
        }, 100);
    }
