HTML5脚本标签需要 type = “ javascript”吗？

可能的复制品:
是否需要在 < script > 标记中指定 text/javascript

在 HTML5中，<script>标记需要属性 type="text/javascript"吗？
我的意思是，如果 <script>标签包含 javascript，这不是很明显吗？

No, it's now officially useless.

The type attribute gives the language of the script or format of the data. If the attribute is present, its value must be a valid MIME type. The charset parameter must not be specified. The default, which is used if the attribute is absent, is "text/javascript".

Simply do

<script src=yourpath.js></script>

(yes, you can omit the quotes too)

Note that you don't have to worry about pre-HTML5 browsers, all of them always considered JavaScript to be the default script language.

From the spec:

If the language is not that described by "text/javascript", then the type attribute must be present

And:

The default, which is used if the attribute is absent, is "text/javascript".

Conversely, that means that if your src attribute is for a file that is valid JavaScript, it is not needed.
