Js判断flash是否被禁用,如果禁用并开启flash

<script>
    function flashChecker() {
        var hasFlash = 0;     //是否安装了flash
        var flashVersion = 0;   //flash版本
        if(document.all) {
            var swf = new ActiveXObject('ShockwaveFlash.ShockwaveFlash');
            if(swf) {
                hasFlash = 1;
                VSwf = swf.GetVariable("$version");
                flashVersion = parseInt(VSwf.split(" ")[1].split(",")[0]);
            }
        } else {
            if(navigator.plugins && navigator.plugins.length > 0) {
                var swf = navigator.plugins["Shockwave Flash"];
                if(swf) {
                    hasFlash = 1;
                    var words = swf.description.split(" ");
                    for(var i = 0; i < words.length; ++i) {
                        if(isNaN(parseInt(words[i]))){
                            continue;
                        }
                        flashVersion = parseInt(words[i]);
                    }
                }
            }
        }
        return {
            f: hasFlash,
            v: flashVersion
        };
    }
    var fls = flashChecker();
    if(fls.f){
        alert(123456);
        document.write("您安装了flash,当前flash版本为: " + fls.v + ".x");
    }else {
        alert(76543);
        document.write("您没有安装flash");
    };

    if(fls.f){

        // liveType.ckplayer();
        alert("您安装了flash,当前flash版本为: " + fls.v + ".x");
    }else {
        //alert("您没有安装flash");

        alert('<a href="https://get.adobe.com/cn/flashplayer/"; class="flashLoadMsg" target="_blank">安装或者启用FLASH播放器</a>');
    };
</script>
