您的问题似乎很明确，但实际上可能并非如此.原因如下:您想如何使用此功能?如果希望有一个JavaScript函数，如果在浏览器中禁用了JavaScript，则该函数返回false，请考虑一下:它永远不会被调用，因为……好吧，因为禁用了JavaScript. :-)它总是返回true或不被调用. :-)

而且，没有任何可靠的方法可以在服务器端使用PHP进行检查.这件事不是任何标准协议的一部分.例如，请参见: http://www.codingforums.com/showthread.php?t=138190 [ ^ ].

因此，您所能做的就是使用HTML noscript， http://www.w3schools.com/tags/tag_noscript.asp [ ^ ].

It looks like your question is very clear, but in fact it is probably not. Here is why: How you want to use this feature? If you hoped to have a JavaScript function which returns false if JavaScript is disabled in the browser, think about it: it will never be called because… well, because JavaScript is disabled. :-) It would always return true or not called. :-)

And there is no any reliable way to check it on server side with PHP. This matter is just not a part of any standard protocol. For example, see this: http://www.codingforums.com/showthread.php?t=138190[^].

So, all you can do is using HTML noscript, http://www.w3schools.com/tags/tag_noscript.asp[^].
