I resolved my problem after a no.我在拒绝后解决了我的问题。 of attempt and would like to share:尝试并想分享：
<script type="text/javascript">
window.document.close();
</script>
Why were not js functions working even after downloading the files: because of i was opening (pop up) a new window using window.document.write() and this method was causing the problem so i used window.document.close() to force a page to 'finish loading'.为什么即使在下载文件后 js 功能也不能工作：因为我正在使用window.document.write()打开（弹出）一个新的 window 并且这种方法导致了问题，所以我使用window.document.close()强制页面“完成加载”。

var h = document.getElementsByTagName('head')[0],
s = document.createElement('script');
s.type = 'text/javascript';
s.onload = function () { document.getElementById('hello').innerText = h.innerText; };
s.src = 'http://html5shiv.googlecode.com/svn/trunk/html5.js';
h.appendChild(s);
