如何使用javascript检测平板电脑,手机,桌面,电视 [英] How to detect tablet, mobile, desktop, tv using javascript
问题描述
我正在开发一个Web应用程序,我需要从javascript中检测设备。谁有人告诉我最好的方法呢?我通过谷歌搜索找到了几个解决方案。但没有人能够充分证明。我不想像WURFL一样使用服务器端检测。
我的更新
我通过匹配检测设备使用javascript的CSS媒体查询。使用保罗爱尔兰的polyfill进行媒体查询匹配

我建议你查看 http:/ /wurfl.io/
简而言之,如果您导入一个微小的JS文件:
< script type ='text / javascript'src =// wurfl.io/wurfl.js\"></script>
您将留下一个类似于以下内容的JSON对象:
{
complete_device_name:Google Nexus 7,
is_mobile:true,
form_factor:平板电脑
}
(假设您使用的是Nexus 7)将能够执行以下操作:
if(WURFL.form_factor ==Tablet){
//做东西();
}
这就是你要找的。 p>

I am developing an web application where I need to detect the device from javascript. Could anybody tell me whats the best way to do it ? I found several solution by googling. But no one is full proof. I do not want to use server side detection like WURFL.
My update
I am detecing device by matching CSS media queries using javascript. For media query matching using polyfill by Paul Irish https://github.com/paulirish/matchMedia.js/
I advise you check out http://wurfl.io/
In a nutshell, if you import a tiny JS file:
<script type='text/javascript' src="//wurfl.io/wurfl.js"></script>
you will be left with a JSON object that looks like:
{
"complete_device_name":"Google Nexus 7",
"is_mobile":true,
"form_factor":"Tablet"
}
(that's assuming you are using a Nexus 7, of course) and you will be able to do things like:
if(WURFL.form_factor == "Tablet"){
//dostuff();
}
This is what you are looking for.
