Reliable Way to Detect Desktop vs. Mobile Browser
提问by moey
Possible Duplicate:
What is the Best way to do Browser Detection in Javascript?
I'd like to essentially do the following (in JavaScript or PHP):
我想基本上执行以下操作（在 JavaScript 或 PHP 中）：
if (desktop browser) {
do x;
}
else { // mobile browser
do not do x;
}
It is known that using a browser detection method is not recommended. A better solution is using a capability testing. My question is, with mobile browsers become smarter and as powerful as the desktop version, what ideally exclusive capability detection to filter the desktop from non-desktop browsers?
众所周知，不推荐使用浏览器检测方法。更好的解决方案是使用能力测试。我的问题是，随着移动浏览器变得与桌面版本一样智能和强大，理想情况下，从非桌面浏览器中过滤桌面的唯一功能检测是什么？
I think reversing the conditional check i.e. if (mobile browser) {} else ...might prove to be more problematic, right?
我认为反转条件检查 ieif (mobile browser) {} else ...可能会被证明更有问题，对吧？

What a little Google search turned up, from A Beautiful Site:
一个小小的谷歌搜索出现了，来自一个美丽的网站：
var isMobile = {
Android: function() {
return navigator.userAgent.match(/Android/i);
},
BlackBerry: function() {
return navigator.userAgent.match(/BlackBerry/i);
},
iOS: function() {
return navigator.userAgent.match(/iPhone|iPad|iPod/i);
},
Opera: function() {
return navigator.userAgent.match(/Opera Mini/i);
},
Windows: function() {
return navigator.userAgent.match(/IEMobile/i);
},
any: function() {
return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Opera() || isMobile.Windows());
}
};
if(isMobile.any()){
// Mobile!
} else {
// Not mobile
}
I will not argue that feature detection is waypreferable to user-agent sniffing, which is terrible actually. But if you're detecting feature to determine whether or not the device is considered mobile or not, you're exposing yourself to a whole new serie of problems.
我不会说这个功能检测方法最好用户代理嗅探，这是可怕的实际。但是，如果您正在检测功能以确定设备是否被视为移动设备，那么您将面临一系列全新的问题。
You can't check pixel-ratiobecause new desktops computers will most likely be "retina" or super-HD. You can't check device-orientationbecause it's not something unique to mobiles anymore. You can't check (if you can) the gyroscope because some laptop might return values.
您无法检查，pixel-ratio因为新的台式计算机很可能是“视网膜”或超高清。您无法检查，device-orientation因为它不再是手机独有的东西。您无法检查（如果可以）陀螺仪，因为某些笔记本电脑可能会返回值。

I think you're looking for the get_browser()function in php.
我认为您正在php 中寻找get_browser()函数。
Attempts to determine the capabilities of the user's browser, by looking up the browser's information in the browscap.ini file.
尝试通过在 browscap.ini 文件中查找浏览器信息来确定用户浏览器的功能。
