页面加载后在html正文中注入外部javascript文件 [英] Inject external javascript file in html body after page load

问题描述

我想在加载页面后加载外部JavaScript。实际上，javascript包含广告的来源，并且其制作页面加载速度很慢。我只想延迟加载和执行广告以确保快速加载页面。

推荐答案

您可以在主体块的最后一个标签处使用此脚本：

You may just use this script at the last tag of your body block:

<script type="text/javascript">
   var script = document.createElement('script');
   script.setAttribute('src', 'http://yourdomian.com/your_script.js');
   script.setAttribute('type', 'text/javascript');
   document.getElementsByTagName('head')[0].appendChild(script);
</script>
