【问题描述】:
我想在新的 Facebook 时间线的 iFrame 选项卡页面内有一个“转到顶部”链接,已尝试按如下方式使用 FB.Canvas.scrollTo 但无法正常工作。任何指针不胜感激!
<body style="overflow: hidden">
<div id="fb-root"></div>
<script>
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
// Init the SDK upon load
window.fbAsyncInit = function() {
FB.init({
appId : 'myAppID',
channelUrl : 'my_channel.html',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
document.getElementById('go_to_top').addEventListener('click', function(){
FB.Canvas.scrollTo(0,0);
});
<div id="goToTop">
<img border=0 src ="aPicForClicking.jpg">
</div>
</body>
