需求:打开页面只看到DIV2,等完秒数之后在显示DIV3。手动关闭DIV3后在重新数秒

我设置的间隔时间是3秒,代码如下:

html+css:

1: <!DOCTYPE HTML>
html>
head>
meta http-equiv="content-type" content="text/html;charset=utf-8">
title>Test</title>
style type="text/css">
   8:         height: 300px;
  10:         margin:0 auto;
  12:       }
  14:         margin:10px;
  16:       .div2{
  18:         height: 100px;
  20:       }
  22:         border: 1px dashed red;
  24:         height: 100px;
  26:       }
style>
head>
body>
div class="div1" id="div1">这是div1
<span id="showTime"></span> -->
div class="div2" id="div2">这是div2</div>
div class="div3" id="div3">这是div3
button id="closeDiv3">关闭div3</button>
div>
div>
body>
html>

js:

1: window.onload =function() {
   3:        var div2 = document.getElementById("div2");
   5:        var closeDiv3 = document.getElementById('closeDiv3');
   7:  
   9:        var countTime = 6;
  11:        function controlTime()
  13:          /*showTime.innerHTML = countTime +"秒后div2隐藏,div3显示";*/
  15:          countTime--;
  17:          {
  19:            div2.style.display = "none";
  21:            /*showTime.innerHTML = countTime1 +"秒后div3隐藏,div2显示";*/
  23:            {
  25:              div3.style.display = "none";
  27:            }
  29:        }
  31:        div3.onmouseover = function(){
  33:          closeDiv3.onclick = function(){
  35:            div3.style.display = "none";
  37:            /*showTime.innerHTML = countTime+"秒后div2隐藏,div3显示";*/
  39:        }
  40:       }
