text / javascript和application / javascript有什么区别？
如果你已经将类型属性设置为application / javascript，那么IE将完全忽略脚本标记。
但主要区别是什么，在这种情况下我们需要使用特定的。
文字/ javascript是在网络年轻时引入的，人们还没有想过。
然后人们考虑了事情，并决定将text / *保留用于人类可读的东西（这就是为什么有些XML是text / xml和其他XML是appli阳离子/ XML）。 JavaScript不是人类可读的，因此不推荐使用text / javascript并引入application / javascript来替换它。
多年以后，一些浏览器仍然没有赶上。 / p>
您可以将服务器配置为始终在HTTP标头中提供application / javascript;不支持它的浏览器也不关注实际的内容类型。
目前，如果您正在编写HTML 4或XHTML 1，请指定文本为了向后兼容性，在type属性中使用/ javascript。如果您正在编写HTML 5，则省略type属性（因为它现在是可选的）。

what is difference between text/javascript and application/javascript?
As IE will completely ignore the script tag if you have set type attribute to application/javascript.
But what is the main difference and in which case we need to use the particular.
text/javascript was introduced when the web was young and people hadn't thought things through.
Then people thought things through, and decided that text/* should be reserved for things designed to be human readable (which is why some XML is text/xml and other XML is application/xml). JavaScript is not human readable, so text/javascript was deprecated and application/javascript was introduced to replace it.
Years later, some browsers still haven't caught up.
You can configure your server to always serve application/javascript in the HTTP headers; browsers that don't support it also pay no attention to the actual content-type.
For the time being, if you are writing HTML 4 or XHTML 1, specify text/javascript in the type attribute for the sake of backwards compatibility. If you are writing HTML 5, then omit the type attribute (as it is now optional).
