使用Javascript檢測Chrome瀏覽器和Safari瀏覽器

-3

我想顯示消息「您沒有使用Chrome瀏覽器，點擊此處下載Chrome瀏覽器，但如果瀏覽器使用的是Safari瀏覽器，我不希望顯示消息。（使用IE瀏覽器（太糟糕了）和FF（太重）或任何其他瀏覽器（除Safari之外，因爲不錯，並且因爲任何其他第三方瀏覽器可能安裝在Apple OS上都會有不好的表現）使用Chrome（理想選擇對於使用Javascript檢測Chrome瀏覽器和Safari瀏覽器

我的應用程序的最佳用戶體驗），我發現了一個腳本，誰似乎很好地適應於做一個可靠的檢測，但我不知道如何自定義代碼：

var BrowserDetect = { 
init: function() { 
    this.browser = this.searchString(this.dataBrowser) || "An unknown browser"; 
    this.version = this.searchVersion(navigator.userAgent) 
     || this.searchVersion(navigator.appVersion) 
     || "an unknown version"; 
    this.OS = this.searchString(this.dataOS) || "an unknown OS"; 
}, 
searchString: function (data) { 
    for (var i=0;i<data.length;i++) { 
     var dataString = data[i].string; 
     var dataProp = data[i].prop; 
     this.versionSearchString = data[i].versionSearch || data[i].identity; 
     if (dataString) { 
      if (dataString.indexOf(data[i].subString) != -1) 
       return data[i].identity; 
     } 
     else if (dataProp) 
      return data[i].identity; 
    } 
}, 
searchVersion: function (dataString) { 
    var index = dataString.indexOf(this.versionSearchString); 
    if (index == -1) return; 
    return parseFloat(dataString.substring(index+this.versionSearchString.length+1)); 
}, 
dataBrowser: [ 
    { 
     string: navigator.userAgent, 
     subString: "Chrome", 
     identity: "Chrome" 
    }, 
    { 
     string: navigator.vendor, 
     subString: "Apple", 
     identity: "Safari", 
     versionSearch: "Version" 
    } 
] 

}; 
BrowserDetect.init();

有人可以幫忙嗎？如果需要我在這裏找到該腳本：

爲什麼你不正確地寫你的web應用程序，而不是強迫用戶使用特定的瀏覽器？ – Blender

爲什麼你不嘗試類似這樣的東西：http://stackoverflow.com/a/12625944/487940。然後，您可以稍作修改以顯示您的消息。此外，強迫用戶瀏覽器的主意不好。如果需要，您應該展示一些更友好的信息：「爲獲得最佳體驗，請下載並使用Google Chrome」。 IE已經有了很大的改進，所以不要低估它。 – harsimranb

檢測功能，而不是瀏覽器 – Eric

回答這個問題... :) 如果你真的想使用它，那麼就使用BrowserDetect.browser作爲指南。我使用了http://www.quirksmode.org/js/detect.html的代碼。
