刮刮乐怎么做？

来这我教你

1、首先准备好编程软件webStorm或者eclipse都行
2、不会编写代码？给你准备好了
3、如下

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
  <style>
    .outer{
      height: 90px;
      width: 300px;
      margin: 0 auto;
      margin-top: 5px;
    }
    .box{
      height: 70px;
      width: 70px;
      background-color: darkgray;

      line-height: 70px;
      text-align: center;
      display: inline-block;
      margin-left: 5px;
    }

  </style>
</head>
<body>
<div class="outer">
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
</div>
<div class="outer">
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
</div>
<div class="outer">
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
</div>

<script>
  var boxs = document.getElementsByClassName("box");
  var item = ["一等奖","二等奖","三等奖","谢谢","谢谢","谢谢","谢谢","谢谢","谢谢",];


  for (var i = 0;i<boxs.length;i++){
    var box = boxs[i];
    box.onclick = function (){
      this.style.backgroundColor="red";
      //this.innerText="一等奖"；//随即从数组中获取内容，并且不能重复！
      var number = Math.floor(Math.random()*9);
      this.innerText = item[number];
      this.style.color = "#fff";
      this.style.verticalAlign = "top";
    }
  }
</script>
</body>
</html>

4、这个部分的代码块文字内容可以自定义，改写成你想要显示的内容

5、最终网页显示界面如下
