想写个脚本秒刷视频的。我感觉控制时长的代码应该在这里面，我是小白求大神帮助。

if (typeof(player) == "undefined")
player = new Object();
player.player_time = 0;
player.hide = 0;
player.src;
player.duration;
player.currentIndex = 0;
player.otherClips=true;
player.init = function () {
player.switchClarity(player.clarity_id);
var video=$("#" + player.player_id);
video[0]['disablePictureInPicture']=true;//去掉画中画
$("#" + player.player_id).bind("ended", function () {
//player.play(curr);

    if(switchPlayList.length==1||curr >= switchPlayList.length){
        $("#"+player.player_id)[0].pause();

    }else{
        player.play(curr);
    }

})

};
setInterval(function(){
if(player.getState()==3)
player.player_time++;
},1000);

player.getSrc = function(){
return player.src;
}
player.setSrc = function(src){
player.src = src;
}

player.realy = function(){
return $("#"+player.player_id)[0].readyState == 4;
}
player.play = function (stat) {
if (typeof(stat) == "undefined"||"number") {
//$("#"+player.player_id)[0].play();
videoPlay(stat);

}else{
    $("#"+player.player_id)[0].pause();
}

};

function videoPlay(i){
// $("#"+player.player_id).attr("src",switchPlayList[i].url);

    if($("#course_player")){
        var videoTag="<video id='course_player' width='640px' height='360px'  controls='controls' controlsList='nodownload' preload='preload' oncontextmenu='return false;'>"+

这种还是推荐哥哥学一下自己写...
别人即使看代码也没啥用的
