如果是分享到facebook，需要翻墙软件哦（蓝灯或者赛风，鄙人两个都用过，还可以）
第一种：百度里的分享按钮http://share.baidu.com/code
摘要做的分享按钮的代码
<div class="bdsharebuttonbox">
<a href="#" class="bds_more" data-cmd="more"></a>
<a href="#" class="bds_qzone" data-cmd="qzone"></a>
<a href="#" class="bds_tsina" data-cmd="tsina"></a>
<a href="#" class="bds_tqq" data-cmd="tqq"></a>
<a href="#" class="bds_renren" data-cmd="renren"></a>
<a href="#" class="bds_weixin" data-cmd="weixin"></a>
<a href="#" class="bds_fbook" data-cmd="fbook"></a>
<a href="#" class="bds_twi" data-cmd="twi"></a>
<script>
window._bd_share_config={"common":{"bdSnsKey":{},"bdText":"","bdMini":"2","bdPic":"","bdStyle":"0","bdSize":"16"},"share":{},"image":{"viewList":["qzone","tsina","tqq","renren","weixin","fbook","twi"],"viewText":"分享到：","viewSize":"16"},"selectShare":{"bdContainerClass":null,"bdSelectMiniList":["qzone","tsina","tqq","renren","weixin","fbook","twi"]}};
with(document)0[(getElementsByTagName('head')[0]||body).appendChild(createElement('script')).src='http://bdimg.share.baidu.com/static/api/js/share.js?v=89860593.js?cdnversion='+~(-new Date()/36e5)];
</script>
第二种：
