1、节流

创建一个div

<div class="boss">1</div>

js控制

var boss=document.querySelector(".boss");
/*获取*/
var num=parseInt(boss.innerHTML);
/*转类型*/
var bossTime=null;
   var bol=true;
     boss.onclick=function () {
         if(bol){
             bol=false;
             bossTime=setTimeout(function () {
                 num++;
                 boss.innerHTML=num;
                 bol=true;
             },1000)
         }
     }

2、防抖

boss.onclick = function(){
 	clearTimeout(bossTime);
 	if(bol){
 		num++;
 		boss.innerHTML = num;
 		bol=false;
 	}else{
 		bossTime = setTimeout(function(){
 			bol = true;
 		},1000)
 	}
 }
