通过javascript检测ipad/iphone webview [英] detect ipad/iphone webview via javascript

问题描述

有没有办法用 JavaScript 检测网站是在 iPad 的 Safari 内还是在应用程序 WebView 内运行?

Is there a way to detect with JavaScript if the website runs inside the iPad's Safari or inside an application WebView?

推荐答案

这使用了 window.navigator.userAgent 和 window.navigator.standalone 的组合.它可以区分与 iOS 网络应用相关的所有四种状态:safari(浏览器)、standalone(全屏)、uiwebview 和非 iOS.

This uses a combination of window.navigator.userAgent and window.navigator.standalone. It can distinguish between all four states relating to an iOS web app: safari (browser), standalone (fullscreen), uiwebview, and not iOS.

演示:http://jsfiddle.net/ThinkingStiff/6qrbn/

var standalone = window.navigator.standalone,
    userAgent = window.navigator.userAgent.toLowerCase(),
    safari = /safari/.test( userAgent ),
    ios = /iphone|ipod|ipad/.test( userAgent );

if( ios ) {
    if ( !standalone && safari ) {
        //browser
    } else if ( standalone && !safari ) {
        //standalone
    } else if ( !standalone && !safari ) {
        //uiwebview
    };
} else {
    //not iOS
};
