Google 的抓取工具是否索引异步加载的元素？
我已经为网站构建了一些在页面加载后异步加载的小部件：
<html>
<head>...</head>
<body>
<div>...</div>
<script type="text/javascript">
(function(){
var ns = document.createElement("script");
ns.type = "text/javascript";
ns.async = true;
ns.src = "http://mydomain.com/myjavascript.js";
var s = document.getElementsByTagName("script")[0];
s.parentNode.insertBefore(ns, s);
})();
</script>
</body>
</html>
是否有办法通知 Google 爬虫仅在页面完全加载后（异步 JavaScript 修改 HTML 后）才索引页面？
I've built some widget for websites which is asynchronously loaded after the page is loaded:
<html>
<head>...</head>
<body>
<div>...</div>
<script type="text/javascript">
(function(){
var ns = document.createElement("script");
ns.type = "text/javascript";
ns.async = true;
ns.src = "http://mydomain.com/myjavascript.js";
var s = document.getElementsByTagName("script")[0];
s.parentNode.insertBefore(ns, s);
})();
</script>
</body>
</html>
Is there anyway to notify Google's crawler to index the page only after the page is fully loaded (after the async JavaScript modified the HTML)?

不可以。您必须为异步内容设置静态镜像页面。参见这里：

No. You have to set up static mirror pages for asynchronous content. See here:

从那时起事情就发生了变化：

Things have evolved since then:
