How to close a facebook SDK dialog opened with FB.ui()?
提问by Nick
I'm successfully displaying an invite friend dialog (code shown below). When user clicks skip the iframe/dialog shows a new page. However from this point I can't find a way how to close the iframe/dialog. FB.ui doesn't return any object, there doesn't seem to be a Javascript SDK method and traversing and manipulating with the DOM will be brittle to any FB code changes.
我成功地显示了邀请朋友对话框（代码如下所示）。当用户点击跳过 iframe/对话框显示一个新页面。但是从这一点上我找不到如何关闭 iframe/对话框的方法。FB.ui 不返回任何对象，似乎没有 Javascript SDK 方法，遍历和操作 DOM 对任何 FB 代码更改都很脆弱。
Any ideas?
有任何想法吗？
function popupInviteForm(actionUrl) {
var fbmlString = '<fb:fbml>' +
' <fb:request-form type="POST" content="Play against me in game?" action="' + actionUrl + '" method="post" >' +
' <fb:multi-friend-selector target="_self" exclude_ids="" max="20" cols="4" rows="3" showborder="false" actiontext="Invite friends!" />' +
' </fb:request-form>' +
'</fb:fbml>';
FB.ui({
method: 'fbml.dialog',
fbml: fbmlString,
display: 'dialog',
size: {width:640,height:480}, width:640, height:480
});
$(".FB_UI_Dialog").css('width', $(window).width()*0.8);
}
(Note: I have posted the same question on the facebook forumwith no response. I will update both, should there be an answer on either.)
（注意：我在facebook 论坛上发布了同样的问题，但没有回应。如果有答案，我会更新两者。）

I have same trouble. Second day looking for a solution. And just found one way: for closing active FB dialog you should perform followed code in parent window where FB JS is available and where FB.ui was called:
我有同样的麻烦。第二天寻找解决方案。刚刚找到了一种方法：要关闭活动的 FB 对话框，您应该在 FB JS 可用且调用 FB.ui 的父窗口中执行以下代码：
FB.Dialog.remove(FB.Dialog._active);
So, if you want your invite dialog auto closes and don't redirects to any other page, use these steps:
因此，如果您希望邀请对话框自动关闭并且不重定向到任何其他页面，请使用以下步骤：
1) Set target attr of and as "_self":
1) 将和的目标属性设置为“_self”：
target="_self"
目标=“_自我”
2) create some callback url/page on your site, for example
https://mysite/close_dialog.html
2）例如在您的网站上创建一些回调网址/页面
https://mysite/close_dialog.html
3) Set action attr of as just created url:
3）将动作属性设置为刚刚创建的网址：
action="http://mysite/close_dialog.html"
动作="http://mysite/close_dialog.html"
4) In your close_dialog.html put followed JS:
4）在你的 close_dialog.html 中加入以下 JS：
<script type="text/javascript">
if (document.location.protocol == 'https:') {
document.location = 'http://mysite/close_dialog.html';
} else {
top.window.FB.Dialog.remove(top.window.FB.Dialog._active);
};
</script>
UPDATE:
更新：
5) There is one issue else in this way: FB iframe loaded by https, but if request-form 'action' attr uses 'http' - user will get browser warning. But if request-form 'action' has 'https' - iframe js cant access to parent loaded by 'http'. So, its the reason why you should use action by 'https'
5) 以这种方式还有一个问题：FB iframe 由 https 加载，但如果 request-form 'action' attr 使用 'http' - 用户将收到浏览器警告。但是，如果请求表单“动作”具有“https”-iframe js 无法访问由“http”加载的父级。所以，这就是你应该使用“https”操作的原因
Hope this helps

That doesn't work (at least not for me).
那行不通（至少对我来说不行）。
What I did was simply call the javascript window.close(); function instead of top.window.FB.Dialog.remove(top.window.FB.Dialog._active); and it works.
我所做的只是调用 javascript window.close(); 函数代替 top.window.FB.Dialog.remove(top.window.FB.Dialog._active); 它有效。
<script type="text/javascript">
if (document.location.protocol == 'https:') {
document.location = 'http://mysite/close_dialog.html';
} else {
//alert('some message');
window.close();
};
</script>

i found Igor Reshetnikov's answer did work, but only if i made sure to declare both pages - The one that opens the dialog and close_dialog.html - as part of the same domain using document.domain. so at the top of the script tags in both pages you'ld had to add this line
我发现 Igor Reshetnikov 的答案确实有效，但前提是我确保将两个页面（打开对话框和 close_dialog.html 的页面）声明为使用 document.domain 的同一域的一部分。所以在两个页面的脚本标签的顶部，你必须添加这一行
document.domain = 'mysite.com';
obviously replacing mysite.com with what ever your domain is
显然用你的域名替换 mysite.com

The FB.ui provides an option for a callback function which will be executed after the FB.ui is completed.
FB.ui 为回调函数提供了一个选项，该函数将在 FB.ui 完成后执行。
FB.ui(
{
method: '..........',
..................
},
function(response) {
//write your code here
}
);
Will this help to solve your problem?
这是否有助于解决您的问题？

This closes all dialogs, but may not work with future releases due to access of internal variable _loadedNodes
这将关闭所有对话框，但由于访问内部变量，可能不适用于未来版本 _loadedNodes
if (FB && FB.UIServer && FB.UIServer._loadedNodes) {
var nodes = FB.UIServer._loadedNodes;
if (nodes) {
for (var item in nodes) {
if (nodes[item].type && nodes[item].node && nodes[item].node.close &&
nodes[item].type === "popup") {
nodes[item].node.close();
}
}
}
}

FWIW, my browser's privacy plugin was preventing FB from closing the dialog. I just switched off the privacy plugin and dialog closed itself as expected.
FWIW，我浏览器的隐私插件阻止了 FB 关闭对话框。我刚刚关闭了隐私插件，对话框按预期关闭了。
