在HTML中包含JavaScript文件不能作为

I'd like to include a javascript file on every page of a site. I can do this with:

我希望在站点的每个页面都包含一个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:

这很好——但是由于两个标签之间没有任何区别，我想把它改为:

<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，它就不起作用了——在页面上加载了一行之后什么都没有。

Any ideas why? Thanks

Unfortunately, the HTML specs for REQUIRE a closing tag...

不幸的是，HTML规范需要一个结束标记……

HTML Standard, section 18.2.1

18.2.1 HTML标准,部分

18.2.1 The SCRIPT element

18.2.1脚本元素

Start tag: required, End tag: required

起始标签:required，结束标签:required

This is not a bug, it's standard behavior.

这不是bug，而是标准行为。

Also, empty HTML elements are often not rendered:

此外，空的HTML元素通常不会呈现:

<div style="background:red"></div> displays, <div style="background:red" /> doesn't

display，没有

HTML doesn'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。如果您想使用它们，您需要使用基于xml的doctype并将文件作为xml提供。

XHTML or the xml serialisation of html5 would both work.

XHTML或html5的xml序列化都可以工作。

Here is an example:

这是一个例子:

<?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 .xhtml extension and open it in a modern browser and the self closing tag will work.

将其保存在一个带有.xhtml扩展的文件中，并在一个现代浏览器中打开它，并且自闭标签将起作用。
