这是 Facebook 点赞按钮的代码:
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=101562769948573";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<div class="fb-like" data-href="http://foodjing.com/" data-send="true" data-width="450" data-show-faces="true"></div>
我想用 Jade 写(因为我的索引是一个玉文件)。我该如何做到这一点?
