我创建了一个facebook连接应用程序iframe。我在apps.facebook.com/app-name下使用它。
似乎刷新后，setSize（）方法失败了。有时工作，有时不...（在最新的Firefox和IE下）是否有解决方案？你会建议使用旧的API吗？
测试用例：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>test</title>
<meta name="description" content="test">
</head>
<body>
<div id="fb-root"></div>
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({appId: 'XXXXXXXXX', status: true, cookie: true, xfbml: true});
FB.Canvas.setSize({ width:760,height:3000 });
};
(function() {
var e = document.createElement('script');
e.type = 'text/javascript';
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
e.async = true;
document.getElementById('fb-root').appendChild(e);
}());
</script>
<div style="height:2000px;background:blue;width:760px;">
</div>
</body>
</html>

如果由于某种原因设置了window.name，FB.setAutoSize将不起作用，http://bugs.developers.facebook.net/show_bug.cgi?id=19720在我的情况下，它以某种方式连接到jquery $ .data
window.fbAsyncInit=function(){
FB.Canvas.setSize = function(b) {
if (typeof b!="object")
b={};
b=b||{};
if (b.width==null||b.height==null)
b=FB.copy(b,FB.Canvas._computeContentSize());
b=FB.copy(b,{frame:'iframe_canvas'});
if (FB.Canvas._lastSize[b.frame]) {
var a=FB.Canvas._lastSize[b.frame].height
if(FB.Canvas._lastSize[b.frame].width==b.width&&(b.height<=a&& (Math.abs(a-b.height)<=16)))
return false;
}
FB.Canvas._lastSize[b.frame]=b;FB.Arbiter.inform('setSize',b);
return true;
}
FB.init({
appId:"<?php echo FB_APP_ID; ?>",
status:true,
cookie:true,
xfbml:true
});
FB.Canvas.setAutoResize()
};
