第二步那个代码是要复制到哪里？我复制进去就是显示一个文本。而非按钮。而其它的如一键关注的代码，复制进去就可以正常显示。类似这样：
<script type="text/javascript">document.write('<iframe width="260" height="489" frameborder="0" scrolling="no" src="http://widget.weibo.com/relationship/bulkfollow.php?language=zh_cn&uids=1642909335,1782515283&wide=1&color=C2D9F2,FFFFFF,0082CB,666666&showtitle=1&showinfo=1&sense=0&verified=1&count=5&refer='+encodeURIComponent(location.href)+'&dpc=1"></iframe>')</script>

放单独的script标签里面吧
