在Script Src标记中包含脚本? < script> (JavaScript等) [英] Having Script within a Script Src tag? <script> (JavaScript etc)

问题描述

为什么这不起作用?

<script type="text/javascript" src="//cdn.com/assets/js/jquery.js">
alert("Hello World!");
</script>

但这是吗?

<script type="text/javascript" src="//cdn.com/assets/js/jquery.js"></script>
<script type="text/javascript">
alert("Hello World!");
</script>

这在从源中提取的许多HTML标记中很普遍. 微观优化对我来说很重要，我也很好奇.

This is general across many HTML tags that pull from source. Micro optimization is important in my situation and I am also curious.

推荐答案

来自 w3.org (重点是我):

如果src具有URI值，则用户代理必须忽略元素的 内容，然后通过URI检索脚本.

If the src has a URI value, user agents must ignore the element's contents and retrieve the script via the URI.
