Facebook通过Parse和Javascript登录

Question

Facebook通过Parse和Javascript登录

Spi*_*lot 0 facebook-javascript-sdk parse-platform

我希望在用户点击链接后显示facebook登录/注册框,但它不起作用.Parse应该使用自己的init函数加载FB SDK,并且应该使用自己的另一个函数显示登录框.我直接从他们的文档中复制并粘贴了代码,因此我认为这不是语法问题.我也尝试在不同的地方初始化Parse SDK,但似乎并不重要.我知道jquery函数正在运行,因为我已经使用警报功能测试它,当我点击目标链接时它会触发,但是登录框不会显示.
我需要修理什么？

<body>
     <div id="fb-root"></div>
<script>

    // Initialize the Parse SDK!

           Parse.initialize("***********","***********");

window.fbAsyncInit = function() {


  //initialize Facebook SDK via Parse

      Parse.FacebookUtils.init({

      appId      : '***********', // App ID from the App DashboardD
      channelUrl : '//http://spilot.koding.com/channel.html', // Channel File for x-domain communication
      status     : true, // check the login status upon init?
      cookie     : true, // set sessions cookies to allow your server to access the session?
      xfbml      : true  // parse XFBML tags on this page?
    });

     // Additional initialization code such as adding Event Listeners goes here
        // use Parse SDK to show Facebook login/registration box after user clicks link

        $("a").click(function(){
                      Parse.FacebookUtils.logIn(null, {
                  success: function(user) {
                    if (!user.existed()) {

<script type="text/javascript">     
// Initialize the Parse object first.
Parse.initialize("XXXXXXXXXX", "YYYYYYYYYYYYY");

window.fbAsyncInit = function() {
    Parse.FacebookUtils.init({
        appId      : 'ZZZZZZZZZZZZZZZ', 
        status     : true, 
        cookie     : true, 
        xfbml      : true
    });
    Parse.FacebookUtils.logIn(null, {
