实现超星网课自动播放

废话不多说直接上代码，放在console 里面运行

var fa = $("body");
var btn = $("
");
var json = {
    "background": "#31e16d",
    "height": "16px",
    "padding": "5px",
    "z-index": 999999,
    "cursor": "pointer",
    "top": "300px",
    "right": "120px",
    "position": "fixed"
};
btn.css(json);
btn.html("开启自动播放模式");
fa.append(btn);

btn.click(function () {
    var i = 2; //那一章 下标  我看到了地二章
    var j = 1; //节 下标
var time = setInterval(function () {
    //获取iframe
    var video = $("iframe").contents().find("iframe").contents();
    //播放函数
    var play = function () {
        video.find("#video > button").click();  //点击播放按钮
        var jy = video.find("#video > div.vjs-control-bar > div.vjs-volume-panel.vjs-control.vjs-volume-panel-vertical > button");
        if (jy.attr("title") != "取消静音") {
            jy.click()
        }
    };
    //正在加载
    var load = video.find("#loading");
    if (load.css("visibility") != "hidden") {
        return;
    }
    //获取进度
    var spans = video.find("#video > div.vjs-control-bar > div.vjs-progress-control.vjs-control > div").attr("aria-valuenow");
    // 如果还没播放完
    if (spans != 100) {
       play();
    }
    //如果播放结束  进行下一次播放
    if (spans == 100) {
        j+=1;
        var allcells = $(".onetoone").find(".cells");  //所有章
        var allncells = $(allcells[i]).find(".ncells"); //所有节
        if (j >= allncells.length){
            i+=1;
            j=0;
            allncells = $(allcells[i]).find(".ncells"); //所有节
        }
        if (i >=allcells.length){  //停止播放
            clearInterval(time);
            return false;
        }
        var a = $(allncells[j]).find("a").attr("href");
        //获取 getTeacherAjax('204834487','9589145','158704904');
        var KhindexOf = a.indexOf("(");
        var KhlastIndexOf = a.lastIndexOf(")");
        var aStr = a.slice(KhindexOf+1,KhlastIndexOf);
        aStr = aStr.match(/'(\S*)'/)[1];
        var reg = new RegExp("'", "g");
        aStr = aStr.replace(reg, "");
        var aArr = aStr.split(",");
        getTeacherAjax(aArr[0],aArr[1],aArr[2]);
    }
    $("#lfsenior").html("自动模式已开启,本章进度:" + spans + "%");
}, 100);
