我发布到Facebook后如何关闭弹出窗口?

use*_*084 8 javascript sdk jquery facebook dialog

在我们的博客上,我们有一个链接,用户可以将文章发布到他们的时间表.弹出窗口打开并且用户发布到Facebook,然后弹出窗口停留在那里并重定向到"www.oursite.com".当用户完成发布或点击取消按钮时,我们如何关闭弹出窗口?根据这个问题,它无法完成,但赫芬顿的帖子已经弄明白,但看着他们的代码,我们无法弄明白.例如,这里的facebook分享按钮将打开一个弹出窗口,然后在您发布文章或取消时关闭.

这是我们拥有的:

FB.init({appId: "90210", status: true, cookie: true});

      function postToFeed() {

        // calling the API ...
        var obj = {
          method: 'feed',
          redirect_uri: 'http://www.oursite.com/',
          link: 'http://www.oursite.com/',
          picture: 'http://www.oursite.com/png.png',
          name: 'Some title',
          caption: '',
          description: ''
        };

        function callback(response){
           window.close(); // doesn't do anything
          //document.getElementById('msg').innerHTML = "Post ID: " + response['post_id'];
        }

        FB.ui(obj, callback);
      }

我们尝试过添加window.close(); 在回调(以及self.close();)中,尝试将redirect_uri留空(并尝试完全退出redirect_uri,但这是必需的).

似乎接受的答案不再有效,因为facebook现在在散列后删除任何内容并用post_id = xxxxx替换它.

解决方案#1(如果你相信FB不会在不久的将来改变它):

if(window.location.search.indexOf('post_id')==1) window.close();

解决方案#2(如果你想要更改保险,不要介意第二个文件):创建一个新的html文件closewindow.html:

<html><body><script>window.close()</script></body></html>

并在重定向中链接到它.

重定向到http://oursite.com/#close_window.然后在您网站的主页上,包含以下内容:

if (window.location.hash == '#close_window') window.close();.

花了一整天的时间研究这个问题后,我有一个非常好的解决方案,我想分享.我没有使用带有FB.ui()的SDK,而是发现我可以通过手动打开自己的弹出窗口来完全避免它.http://www.facebook.com/dialog/feed.这样做时,redirect_uri按预期工作.只要您要求用户单击按钮以弹出对话框,就不会触发弹出窗口阻止程序.

我不相信这个代码有任何妥协,如果有的话,它比实际的SDK更容易使用.

我的Javascript代码(可以保存为FacebookFeedDialog.js)如下所示:

/* by Steven Yang, Feb 2015, originally for www.mathscore.com.  This code is free for anybody to use as long as you include this comment.  */
function FacebookFeedDialog(appID, linkTarget, redirectTarget) {
  this.mParams = {
    app_id: appID,
    link: linkTarget,
    redirect_uri: redirectTarget,
    display: "popup"
  }
};

/* Common params include:
   name - the title that appears in bold font
   description - the text that appears below the title
   picture - complete URL path to the image on the left of the dialog
   caption - replaces the link text
*/
FacebookFeedDialog.prototype.addParam = function(key, value) {
  this.mParams[key] = value;
};

FacebookFeedDialog.prototype.open = function() {

  var url = 'https://www.facebook.com/dialog/feed?' + encodeCGIArgs(this.mParams);
  popup(url, 'feedDialog', 700, 400);
};

/* Takes a param object like this:
   { arg1: "value1", arg2: "value2" }
   and converts into CGI args like this:
   arg1=value1&arg2=value2

   The values and args will be properly URI encoded
*/
function encodeCGIArgs(paramObject) {

  var result = '';

  for (var key in paramObject) {
    if (result)
      result += '&';
    result += encodeURIComponent(key) + '=' + encodeURIComponent(paramObject[key]);
  }

  return result;
}

function popup(mylink,windowname,width,height) {
  if (!window.focus) return;
  var href;
  if (typeof(mylink) == 'string')
    href=mylink;
  else
    href=mylink.href;
  if (!windowname)
    windowname='mywindow';
  if (!width)
    width=600;
  if (!height)
    height=350;
  window.open(href, windowname, 'resizable=yes,width='+width+',height='+height+',scrollbars=yes');

这是一个使用上面的Javascript代码的示例HTML文件:

<HTML>
<BODY>
<SCRIPT type="text/javascript" src="FacebookFeedDialog.js"></SCRIPT>
<SCRIPT>
var dialog = new FacebookFeedDialog(yourAppIDGoesHere,yourDestinationURLGoesHere,yourCloseWindowURLGoesHere);
dialog.addParam('name','This is my title');
dialog.addParam('description','This is the description');
dialog.addParam('picture',yourImageURLGoesHere);
dialog.addParam('caption','This is the caption');
</SCRIPT>

<A href="javascript:dialog.open()">Open facebook dialog</A>
</BODY>

截至 2017 年 10 月,删除redirect_uri似乎有效。

它将默认为https://www.facebook.com/dialog/return/close#_=_

其来源只是 <script type="text/javascript"> window.close() </script>
