我尝试将 Google+ 按钮添加到我的页面。按钮本身有效,但文本和图像始终为空。我用 schema.org 标签注释了我的身体和一些元素,但它不起作用。我在这里做错了什么?
<body itemscope itemtype="http://schema.org/Article">
<div itemprop="name">This is the article name</div>
<img itemprop="image" src="thumbnail.jpg" />
<p itemprop="description">This is the description of the article.</p>
<g:plus action="share" href="testUrl"></g:plus>
<script type="text/javascript">
window.___gcfg = {
lang: 'en-US'
};
(function() {
var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
po.src = 'https://apis.google.com/js/plusone.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
})();
</script>
</body>
