当我尝试使用Javascript SDK删除应用程序请求时,它会向FireBug返回一个错误对象:“load-error:unknown。”

这是一个使用PHP和JS SDK的测试应用程序。

<?php

// This loads the PHP SDK and pulls a user's apprequests
require 'fb-sdk/facebook.php';
$facebook = new Facebook(array(
  'appId'  => 'APP_ID',
  'secret' => 'APP_SECRET',
));
$user = $facebook->getUser();
if ($user) {
  try {
    $user_profile = $facebook->api('/me');
    $user_requests = $facebook->api('/me/apprequests');
    $apprequests = $user_requests['data'];
  } catch (FacebookApiException $e) {
    echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
    $user = null;
  }
}
?>

// This spits out a table of requests with links to delete them.
// The table doesn't reload when you delete a request so you have to refresh.
<table>
<?php foreach ($apprequests as $apprequest) { ?>
  <tr>
  <td><a href="" onClick="deleteRequest('<?php echo $apprequest['id']; ?>')">Delete</a></td>
  </tr>
<?php } ?>
</table>

// This loads the JS SDK and makes a function to delete requests.
<script>
function deleteRequest(requestId) {
  FB.api('/' . requestId, 'delete', function (response) {
    console.log(response);
    // Will have a function to reload the table...
  });
}
window.fbAsyncInit = function() {
  FB.init({
    appId: '<?php echo $facebook->getAppID() ?>',
    cookie: true,
    xfbml: true,
    oauth: true
  });
};
(function() {
  var e = document.createElement('script'); e.async = true;
  e.src = document.location.protocol +
    '//connect.facebook.net/en_US/all.js';
  document.getElementById('fb-root').appendChild(e);
}());
</script>

我知道deleteRequest有效,因为我可以使用此webform手动删除请求:

<input type="text" name="manReqId"></text>
<input type="button"
  onClick="manDelRequest(); return false;"
  value="Delete request"
/>
<script>
function manDelRequest () {
  deleteRequest(document.getElementsByName("manReqId")[0].value);
}
</script>

此方法向FireBug返回“true”。

我假设我编写onClick值的方式有问题。有人能帮助我吗?

对JavaScript SDK说:Facebooks' docs指出应该从点击事件触发操作,以便所有浏览器都能正确显示任何弹出窗口(文档引用FB.login函数,但该警告可能适用于其他电话)。我想知道他们的API是否足够挑剔,它需要一个有效的href属性(即使是#一个短的属性)。

当多个异步请求等待Facebook的服务器时,我也看到了确切的错误。您的代码是否有可能正在处理另一个请求,而删除调用是否会干扰它?
