Include JavaScript file in HTML won't work as <script .... />
提问by Freddie
I'd like to include a javascript file on every page of a site. I can do this with:
我想在网站的每个页面上都包含一个 javascript 文件。我可以这样做：
<script type="text/javascript" src="myFile.js" ></script>
This works fine - however as there's nothing between the two tags, I wanted to change it to:
这工作正常 - 但是由于两个标签之间没有任何内容，我想将其更改为：
<script type="text/javascript" src="myFile.js" />
If I do this, it doesn't work - nothing after that line loads on the page.
如果我这样做，它就不起作用 - 在页面上加载该行之后什么也没有。
Any ideas why? Thanks
任何想法为什么？谢谢

Unfortunately, the HTML specs for REQUIRE a closing tag...
不幸的是，需要一个结束标记的 HTML 规范......
HTML Standard, section 18.2.1
HTML 标准，第 18.2.1 节
18.2.1 The SCRIPT element
Start tag: required, End tag: required
18.2.1 SCRIPT 元素
开始标签：必填，结束标签：必填

This is not a bug, it's standard behavior.
这不是错误，而是标准行为。
Also, empty HTML elements are often not rendered:
此外，通常不会呈现空的 HTML 元素：
<div style="background:red"></div>displays, <div style="background:red" />doesn't
<div style="background:red"></div>显示，<div style="background:red" />不

HTMLdoesn't support self closing tags. If you want to use them you need to use an xml based doctype AND serve the file as xml.
HTML不支持自闭标签。如果你想使用它们，你需要使用基于 xml 的文档类型并将文件作为 xml 提供。
XHTML or the xml serialisation of html5 would both work.
XHTML 或 html5 的 xml 序列化都可以。
Here is an example:
下面是一个例子：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>XHTML5 Template</title>
<meta charset="utf-8" />
<script type="text/javascript" src="http://documentcloud.github.com/underscore/underscore-min.js" />
</head>
<body>
</body>
</html>
Save this in a file with a .xhtmlextension and open it in a modern browser and the self closing tag will work.
将其保存在一个带有.xhtml扩展名的文件中，并在现代浏览器中打开它，自关闭标签将起作用。
