尝试创建滚动脚本，而不是滚动整个html主体，我想只在我的网站滚动推特小部件。

Question

 function scroll(element, speed) {
     element.animate({ scrollTop: $(document).height() }, speed, function() {
         $(this).animate({ scrollTop: 0 }, speed, scroll(element, speed));
     });
 }

 scroll($('html, body'), 1000);

^This is the code I"m running, and it scrolls the entire html view, however I want it to scroll only the twitter widget on my site. I tried doing. 

scroll($('html, .twitter-timeline'), 1000);
scroll($('html, iframe'), 1000);

等。不知道如何选择twitter iframe，哪个类或id负责滚动，所以我可以选择它？
