javascript - 检查黑莓操作系统版本

Question

如何在 Webworks 应用程序中通过 javascript 或 jquery 获取黑莓操作系统版本？

我从线程“detect blackberry os version”中尝试了以下代码，但它对我不起作用:

var limit = '4.5.0.127';
var version = /BlackBerry\w+\/([\d\.]+)/i.exec(navigator.userAgent);
if (version[1] && version[1] < limit) {
    location.href='notcompatible.cfm';
}

<script type="text/javascript">
    var ua = navigator.userAgent;
    if (ua.indexOf("BlackBerry") >= 0) {
        if (ua.indexOf("Version/") >= 0) { // ***User Agent in BlackBerry 6 and BlackBerry 7
            Verposition = ua.indexOf("Version/") + 8;
            TotLenght = ua.length;
            document.write("Jorgesys  BB OS Version :: " + ua.substring(Verposition, Verposition + 3));
        }
        else {// ***User Agent in BlackBerry Device Software 4.2 to 5.0
            var SplitUA = ua.split("/");
            document.write("Jorgesys BB OS Version :: " + SplitUA[1].substring(0, 3));
        }
    }
</script>

• 一定要启用 Javascript! =)
