2.第二種模擬動態方法

代碼:

  display: flex;
  flex: 1;
  margin:.2rem;
}
.demo_warp .active { 
  color:red;
  background-color: cadetblue;

.demo_warp .tab_con {
  width: 100%;
  height: 3rem;
  border:1px solid rgb(85, 85, 177);
  text-align: center;
}

window.onload=function(){
  new Vue({
    el:"#my",
      data:{//響應式的數據 data變化頁面也會跟著變化
     n:0,
     title:["標題一","標題二","標題三","標題四"],
     con:["內容一","內容二","內容三","內容四"]
