                if(timerMenu)

            });
        }
    }, 1000*3);//10s检测一次

收获

1.禁止浏览器弹窗

window.alert=function(){}

2.定时器

var timer = setInterval(() => {
 
	}, 1000*10);//10s检测一次
	
clearInterval(timer);//清除定时器,timer为整数

3.设置属性-隐藏元素

                //ad.setAttribute("display", "none");//不可以
                //Element.style.display = 'none';
                ad.setAttribute('style','display:none');

4.鼠标悬停和移开事件

            document.getElementById('Qsetting').addEventListener('mouseenter',function() {//增加触摸事件mouseover-包括子元素,会导致无法点击子元素
                QsettingBoxs[0].setAttribute("class","dplayer-setting-box dplayer-setting-box-open")
            });
            document.getElementById('Qsetting').addEventListener('mouseleave',function() {//增加触摸事件mouseout-包括子元素,会导致无法点击子元素
                QsettingBoxs[0].setAttribute("class","dplayer-setting-box")
            });

5.添加元素

            $(".dplayer-setting-origin-panel").append(html);
            $(".dplayer-setting-speed-panel").append('<div class="dplayer-setting-speed-item" var=2.5><span class="dplayer-label">2.5</span></div>');
            $(".dplayer-setting-speed-panel").append('<div class="dplayer-setting-speed-item" var=3><span class="dplayer-label">3</span></div>');

6.div里均匀分布

   <div class="dplayer-setting-speed-item" style="display: flex;align-items: center;">
   		<span class="dplayer-setting-speed-item" style="flex: 1;text-align: center;padding: 10px;" var=0.5>0.5</span>
   		<span class="dplayer-setting-speed-item" style="flex: 1;text-align: center;padding: 10px;" var=1>1</span>
   		<span class="dplayer-setting-speed-item" style="flex: 1;text-align: center;padding: 10px;" var=2>2</span>
   </div>

7.获取元素属性值

    $(".className").on("click",function(){
                sp=$(this).attr("属性名");
                console.log(sp)
            });

8.监听播放器状态

https://www.cnblogs.com/yuanmo/p/12795104.html

            video.addEventListener('playing', function () { //播放中
                console.log("播放中");
            });
            video.addEventListener('pause', function () { //暂停中
                console.log("暂停中");
            });
            video.addEventListener('contextmenu', function () { //检测到弹窗 就关闭 // 只能检测手动右键
                console.log("右键点击");
            });
