Facebook iframe FB.Canvas.setAutoGrow does not auto grow after initial load?
提问by Joshc
I have been building a facebook tab using html and css and facebooks javascript SDK.
我一直在使用 html 和 css 以及 facebooks javascript SDK 构建一个 facebook 选项卡。
I having problems with the iframe resizing to the size of the content.
我在将 iframe 调整为内容大小时遇到问题。
I've managed to get it to work on initial load which is cool, using this below script...
我已经设法让它在初始负载上工作，这很酷，使用下面的脚本......
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://ogp.me/ns/fb#">
-
——
<div id="fb-root"></div>
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({
appId : '00000000000000', // App ID
channelUrl : '//www.mywebsite.com/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
FB.Canvas.setAutoGrow();
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
and my channel.html looks like this...
我的 channel.html 看起来像这样......
<?php
$cache_expire = 60*60*24*365;
header("Pragma: public");
header("Cache-Control: max-age=".$cache_expire);
header('Expires: ' . gmdate('D, d M Y H:i:s', time()+$cache_expire) . ' GMT');
?>
<script src="//connect.facebook.net/en_US/all.js"></script>
Like I said the initial page load resizing is perfect, but as I navigate around the iframe, it does not autogrow to my content.
就像我说的初始页面加载调整大小是完美的，但是当我在 iframe 中导航时，它不会自动增长到我的内容。
Can anyone advise as I'm very new to this facebook iframe biz.
任何人都可以提供建议，因为我对这个 facebook iframe biz 很陌生。
Thanks in advance
提前致谢
