navigator.userAgent的 [英] navigator.userAgent
问题描述
navigator.userAgent返回有关用户操作系统的信息，
浏览器等。
通常你会得到类似的东西：
Mozilla / 4.0（兼容; MSIE 6.0; Windows NT 5.1）
或
Mozilla / 4.0（兼容; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET
CLR 1.1.4322）
或
Mozilla / 5.0（Windows; U; Windows NT 5.1; en -US; rv：1.4）Gecko / 20030624
Netscape / 7.1（ax）
imho信息太多，大部分都让用户感到困惑。什么
我想做的是，评估信息和
将它减少到操作系统和浏览器版本。
例如
MSIE 6.0，Windows XP
或
Netscape 7.1，Windows 98
障碍：
- 据我所知，
navigator.userAgent返回的数据结构取决于浏览器。
所以每个浏览器的规格都是一个很好的起点，任何
想法在哪里找？
- 为什么我得到Windows NT 5.1 ;而不是Windows XP？任何其他的
同义词？
我既没有在macs也没有在linux系统上测试它...
我会感谢任何帮助和提示，也许有人做了一些事情
之前类似...
欢呼

是的。并且没有缺陷。
如果userAgent字符串已经被修改，那么它仍然表示某些东西是
。即使它仅仅是因为
查看器使用的浏览器/操作系统允许修改userAgent
字符串。
但这与OP'的问题没什么关系*。当我读到它们时，他们想要知道如何分解userAgent字符串报告的内容，而不是如何识别浏览器/操作系统。

废话。给定一个合适的工具（如PrefBar），我可以这个主机对象返回的
伪* *信息。

navigator.userAgent returns information about the user operting system,
Browser etc.
Usually you get somthing like:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
or
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET
CLR 1.1.4322)
or
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624
Netscape/7.1 (ax)
imho there is too many information, most of it confusing for the user. What
I would like to do is, evaluate the information and
reduce it to the opereting system and browser version.
e.g.
MSIE 6.0, Windows XP
or
Netscape 7.1, Windows 98
obstacles:
- As far as I know, the structure of the data returned by
navigator.userAgent depends on the browser.
So a specification for each browser would be a good starting point, any
ideas where to find?
- Why do I get "Windows NT 5.1" instead of "Windows XP"? Any other
synonyms?
I neither tested it on macs nor linux systems...
I would appreciate any help and hints, maybe somebody has done something
similiar before...
cheers

Yes it does. And without flaw.
If the userAgent string has been modified, then it is still indicative
of certain things. Even if its nothing more than the fact that the
viewer is using a browser/OS that allows the modifying of the userAgent
string.
But that has *nothing* to do with the OP''s question. As I read it, they
wanted to know how to break down what the userAgent string reports, not
how to identify a browser/OS.

Nonsense. Given a suitable tool (like PrefBar), I can
fake *any* information that this host object returns.
