A Parser-blocking, cross-origin script is invoked via document.write - how to circumvent it?
提问by niutech
Google Chrome started implementing Blocking the load of cross-origin, parser-blocking scripts inserted via document.write in the main frameon slow networks, which causes the following error:
谷歌浏览器开始在慢速网络的主框架中实施阻止加载跨域解析器阻止脚本的加载，通过 document.write 插入，导致以下错误：
A Parser-blocking, cross-origin script, http://example.org/script.js, is invoked via document.write. This may be blocked by the browser if the device has poor network connectivity.
通过 document.write 调用解析器阻塞、跨源脚本http://example.org/script.js。如果设备的网络连接不佳，这可能会被浏览器阻止。
However, my web page requires loading a third party script synchronously, using document.write('<script src="..."></script>'). How to circumvent that blockade?

According to Google Developers article, you can:
根据Google Developers 文章，您可以：
- Use asynchronous script loading, using
<script src="..." async>orelement.appendChild(), - Submit the script provider to Google for whitelisting.
- 使用异步脚本加载，使用
<script src="..." async>或element.appendChild()， - 将脚本提供程序提交给 Google 以列入白名单。

Don't use document.write, here is workaround:
不要使用 document.write，这是解决方法：
var script = document.createElement('script');
script.src = "....";
document.head.appendChild(script);
