javascript - 通过 document.write 调用一个解析器阻塞的跨域脚本——如何绕过它？

Question

Google Chrome 开始实现 Blocking the load of cross-origin, parser-blocking scripts inserted via document.write in the main frame在慢速网络上，这会导致以下错误:

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.

但是，我的网页需要同步加载第三方脚本，使用 document.write('<script src="..."></script>') .如何绕过封锁？

根据 Google Developers article ，您可以:
