javascript navigator.javaEnabled函数的意义是什么? [英] What's the point of the javascript navigator.javaEnabled function?

问题描述

navigator对象具有javaEnabled函数，该函数指示浏览器是否具有javascript支持. 这似乎有点奇怪:

The navigator object has a javaEnabled function that indicates if the browser has javascript support. This seems to be a little odd:

• 如果确实启用了JS功能， 显然会返回true.
• 如果禁用了JS，它将返回 < nothing >，因为它永远不会运行， javaScript被禁用.

• If JS is indeed enabled the function will return true, well obviously.
• If JS is disabled it will return <nothing> since it is never run, javaScript is disabled.

我必须在这里丢失一些东西，或者说这个功能真的没用吗?

I must be missing something here, or is it really that useless this function?

推荐答案

java！= javaScript

navigator.javaEnabled检查是否存在 Java ，而不是JavaScript.

navigator.javaEnabled checks for the presence of Java, not JavaScript.
