Facebook的Javascript API第，回调函数？ [英] Facebook Javascript API , callback function?

问题描述

我使用 Facebook的Javascript API第在我的 jQuery Mobile的网站以进口的专辑和照片 页。

I am using Facebooks Javascript API in my jQuery Mobile Website in order to import the albums and photos of a facebook page.

它相当容易使用的API：

Its fairly easy to use the API :

<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
    // init the FB JS SDK
    FB.init({
      appId      : 'YOUR_APP_ID',                        // App ID from the app dashboard
      channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel file for x-domain comms
      status     : true,                                 // Check Facebook Login status
      xfbml      : true                                  // Look for social plugins on the page
    });

    // Additional initialization code such as adding Event Listeners goes here
    FB.api('16907099963/albums', checkForErrorFirst(getAlbums));
  };

  // Load the SDK asynchronously
  (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'));
</script>

正如你看到我在这里做对API的调用： FB.api（'16907099963 /相册，checkForErrorFirst（getAlbums））; 这会给我所有的本页面的专辑。电话是异步。我需要找到一种方法，能够知道什么时候调用完成。但我真的无法找到任何回调函数在这里..

As you see i make a call to the API here : FB.api('16907099963/albums',checkForErrorFirst(getAlbums)); which will give me all the albums of this page. The call is asynchronous. I need to find a way to be able to know when the call has finished. But i really cant find any callback functions here..

该API可以发现这里

原因我问这个，是我需要添加一个jQuery Mobile的加载窗口小部件，之前我调用API，并使其停止时，专辑已经呈现。在这一个任何想法？

The reason i am asking for this , is that i need to add a jquery mobile "loading" widget , before i call the API and make it stop when the albums have rendered. Any idea on this one?

推荐答案

的 checkForErrorFirst 是回调函数。我想你也缺少页面ID前斜线在 FB.api 。快速sollution如果不能修改 checkForErrorFirst 功能：

The checkForErrorFirst is the callback function. I think your are also missing a slash before the page ID in FB.api. Quick sollution if you can't edit the checkForErrorFirst function:

loader.show();
FB.api('/16907099963/albums', function(result) {
  loader.hide();
  checkForErrorFirst(getAlbums)(result);
});
