   var b = Math.floor(Math.random()*256); 
   if(r < 16){ 
    r = "0"+r.toString(16); 
   }else{ 
    r = r.toString(16); 
   } 
   if(g < 16){ 
    g = "0"+g.toString(16); 
   }else{ 
    g = g.toString(16); 
   }

##The following is a piece of code about several ways to generate random colors in js

<!DOCTYPE html>
<html>
<head lang="en">
 <meta charset="UTF-8">
 <title></title>
</head>
<body>
  <button id="btn1">调用第一种</button>
  <button id="bnt2">调用第二种</button>
  <button id="btn3">调用第三种</button>
  <script>
   var btn1=document.getElementById('btn1');
   btn1.onclick=function(){
    document.body.style.background=bg1()
   };
   var btn2=document.getElementById('bnt2');
   btn2.onclick=function(){
    document.body.style.background=bg2();
   };
   var btn3=document.getElementById('btn3');
   btn3.onclick=function(){
    document.body.style.background=bg3();
   };
   function bg1(){
    return '#'+Math.floor(Math.random()*256).toString(10);
   }
   function bg2(){
    return '#'+Math.floor(Math.random()*0xffffff).toString(16);
   }
   function bg3(){
    var r=Math.floor(Math.random()*256);
    var g=Math.floor(Math.random()*256);
    var b=Math.floor(Math.random()*256);
    return "rgb("+r+','+g+','+b+")";//所有方法的拼接都可以用ES6新特性`其他字符串{$变量名}`替换
   }
  </script>
