JS插件检测用户的浏览器，操作系统，语言，地理位置......？

Question

I could have sworn that I saw this on Hacker News a few weeks ago: a simple JS plugin that gives you access to every common bit of information about your user - their OS, browser, language setting, etc.

I'm pretty sure it was a commercial product that was then immediately copied and open-sourced by someone on HackerNews.

But I now can't for the life of me remember what either the commercial product, or the open source plugin, were called.

Can anyone suggest either?

Thanks!

Answer 1

you can use the navigator object to accomplish most of that.

for example you can do things like this:

txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";

but the plugin you are probably looking for is Modernizr

如果您要查找统计信息而不是每个用户的特定信息，则可以使用非侵入式工具（例如Google Analytics（分析））获取有关浏览器和操作系统使用情况的数据。
