Javascript MIME [英] Javascript MIME

问题描述

我想知道是否最好使用application/javascript或application/ecmascript，以及是否应该使用application/languagename而不是其他语言的text/languagename.

I would like to know if is better to use application/javascript or application/ecmascript and if i should use application/languagename instead of text/languagename with other languages.

推荐答案

IANA(官方MIME类型注册表)列出了text/javascript和text/ecmascript已过时(通过 RFC 4329 ).

Officially, IANA (keepers of the official MIME type registry) lists text/javascript and text/ecmascript as obsolete (via RFC 4329).

在这两个中，最容易使用application/javascript. application/ecmascript的使用带来了更严格的字符编码要求，并减少了4329中指定的错误处理.

Of those two, it easiest to use application/javascript. The use of application/ecmascript brings with it stricter character encoding requirements and less forgiving error handling as specified in 4329.

实际上，如果您想在IE中工作，您必须使用text/javascript >.

Practically, you have to use text/javascript if you want it to work in IE.

此外，我的建议是完全跳过<script>标签的type属性.没有浏览器，每个浏览器都可以运行您的JS. (不过，您仍然需要提供HTTP text/javascript为text/javascript的.js文件.)

Also, my recommendation is to skip the type attribute of <script> tags entirely. Every browser will run your JS just fine without. (You still need to serve .js files with a HTTP Content-Type of text/javascript, though.)
