我想显示消息“您没有使用 Chrome，请单击此处下载 Chrome。但如果使用的浏览器是 Safari，我不希望显示消息。实际上我想特别说服使用 IE（太蹩脚）和 FF 的人（太重）或任何其他浏览器（Safari 除外，因为它还不错，并且因为任何其他可以安装在 Apple OS 上的第三方浏览器都会有很差的性能）来代替 Chrome（我的应用程序的理想选择，以获得最佳用户体验） .

我找到了一个似乎很适合进行可靠检测的脚本，但我不知道如何自定义代码：

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();

有人可以帮忙吗？如果需要，我在这里找到了脚本：

回答问题... :) 如果您真的想使用它，那么只需使用 BrowserDetect.browser 作为您的指南。我使用了来自http://www.quirksmode.org/js/detect.html的代码。
