Detect Desktop Browser (not mobile) with Javascript
提问by fabian
I found the following code to detect a desktop browser. But the method also detects some mobile browsers. How can I detect only desktop browsers like Safari, IE, Firefox, Opera etc?
我找到了以下代码来检测桌面浏览器。但该方法也会检测一些移动浏览器。如何仅检测 Safari、IE、Firefox、Opera 等桌面浏览器？
is_desktopBrowser : function() {
var ua = navigator.userAgent.toLowerCase();
var rwebkit = /(webkit)[ \/]([\w.]+)/;
var ropera = /(opera)(?:.*version)?[ \/]([\w.]+)/;
var rmsie = /(msie) ([\w.]+)/;
var rmozilla = /(mozilla)(?:.*? rv:([\w.]+))?/;
var match = rwebkit.exec(ua) ||
ropera.exec(ua) ||
rmsie.exec(ua) ||
ua.indexOf("compatible") < 0 && rmozilla.exec(ua) ||
[];
return { browser: match[1] || "", version: match[2] || "0" };
},

jQuery.browser can be helpful when trying to figure out which browser.jQuery.browserwas removed in jQuery 1.9.
jQuery.browser 在尝试找出哪个浏览器时会很有帮助。jQuery.browser在 jQuery 1.9 中被移除。
I believe it is based on navigator.UserAgent, however navigator.UserAgent can tell you the OS on its own if you want.
我相信它是基于 navigator.UserAgent，但是如果你愿意，navigator.UserAgent 可以自己告诉你操作系统。
Try this:
尝试这个：
var isMobile = navigator.userAgent.match(/(iPad)|(iPhone)|(iPod)|(android)|(webOS)/i)

I check for
我检查
('ontouchstart' in window)
since that will tell me if I'm on a touch capable device. Of course that also returns true for an ipad, which might not be considered a "mobile device", but then I just check window.widthfor layout purposes.
因为这会告诉我我是否在支持触摸的设备上。当然，对于可能不被视为“移动设备”的 ipad，这也返回 true，但我只是检查window.width布局目的。

I came up with this:
我想出了这个：
var isTouchDevice = function() { return 'ontouchstart' in window || 'onmsgesturechange' in window; };
var isDesktop = window.screenX != 0 && !isTouchDevice() ? true : false;
It leverages two things we can hold on to. One, window.screenX will ALWAYS be 0 on any tablet / mobile device. You can't move windows on these devices, it is always full screen.
它利用了我们可以坚持的两件事。一，window.screenX 在任何平板电脑/移动设备上始终为 0。您无法在这些设备上移动窗口，它始终是全屏的。
Two, isTouchDevice is a pretty reliable way to know if it's mobile (android / iphone tablet) or Windows Surfacey thing. It has a touch event. Combining the two gives us a high degree of certainty that it's a mobile or tablet. If you're not one of those, you must be desktop.
第二，isTouchDevice 是一种非常可靠的方式来了解它是移动设备（android / iphone 平板电脑）还是 Windows Surfacey。它有一个触摸事件。将两者结合起来可以让我们高度确定它是手机还是平板电脑。如果您不是其中之一，那么您必须是台式机。
Yes, you might have a desktop that somehow reports itself as touch and has the browser maxxed to the upper left. In my case, I can let that go.
是的，您可能有一个桌面，不知何故将自己报告为触摸，并将浏览器最大化到左上角。在我的情况下，我可以放手。

I have been investigating this for my ReView (Responsive Viewport) project. I use a combination of the following.
我一直在为我的 ReView（响应式视口）项目调查这个。我使用以下组合。
- window.screenX
- 窗口.screenX
Most mobile browsers have the 'window' locked to the left hand side. So if this isn't zero, likely to be a desktop browser window.
大多数移动浏览器都将“窗口”锁定在左侧。因此，如果这不是零，则可能是桌面浏览器窗口。
- window.devicePixelRatio and screen.width
- window.devicePixelRatio 和 screen.width
If dpr is 1 and screen width is reported as large via screen.width, likely to be desktop.
如果 dpr 为 1 并且屏幕宽度通过 screen.width 报告为大，则可能是桌面。
- window.orientation
- 窗口方向
It is rare to find a desktop monitor in portrait mode. However, this could happen.
很难找到纵向模式的桌面显示器。然而，这可能会发生。
More unlikely is multiple orientation changes while using your site/app. This implies a desktop user would be spinning their screen... very unlikely.
更不可能的是在使用您的网站/应用程序时多次更改方向。这意味着桌面用户会旋转他们的屏幕......不太可能。
A combination of these with some common sense and you can achieve a pretty solid guess.
将这些与一些常识结合起来，您就可以得出非常可靠的猜测。

Even it's a bit overkill for your case, express-useragentis one of the best solution as it can be used on both server and browser. Your case:
即使对您的情况来说有点矫枉过正，但express-useragent是最好的解决方案之一，因为它可以在服务器和浏览器上使用。你的情况：
Include js file in HTML
在 HTML 中包含 js 文件
<script type="text/javascript" src="/path/to/express-useragent.js"></script>
Execute the plugin
执行插件
var userAgent = new UserAgent().parse(navigator.userAgent);
Value of userAgentwill be something like
的价值userAgent将是这样的
{
"isMobile":false,
"isDesktop":true,
"isBot":false,
.....
"browser":"Chrome",
"version":"17.0.963.79",
"os":"Windows 7",
"platform":"Microsoft Windows",
"source":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.79..."
}

The problem with your script is, that it's just trying to detect the browser with the UserAgent-string which is not quite accurate because everyone can fake his UserAgent.
你的脚本的问题是，它只是试图用UserAgent-string检测浏览器，这不太准确，因为每个人都可以伪造他的UserAgent.

You can go to http://detectmobilebrowsers.comand generate a JS script which will detect whether a browser is a mobile browser. Unless you are worried about Smart TVs or some other non mobile nor desktop appliances, you can use that script and assume that if the browser is NOT a mobile browser then it should be a desktop browser.
您可以访问http://detectmobilebrowsers.com并生成一个 JS 脚本，该脚本将检测浏览器是否为移动浏览器。除非您担心智能电视或其他一些非移动或桌面设备，否则您可以使用该脚本并假设如果浏览器不是移动浏览器，那么它应该是桌面浏览器。
Here is an example solution using the regex-es generated by that site:
这是使用该站点生成的正则表达式的示例解决方案：

Actually, it is easy to detect mobile or tablet device, then with a simple result inversion we can understand that is desktop or not, for easy accessing I write a simple function:
其实很容易检测到手机或平板设备，然后通过一个简单的结果反演我们就可以知道是不是桌面设备，为了方便访问，我写了一个简单的函数：
