在小程式中實現倒數效果範例程式碼

<!--index.wxml--> 
<view class="container">  
 <text>倒计时: {{second}} </text>  
</view>

//index.js  
// 从从60到到0倒计时  
function countdown(that) {  
 var second = that.data.second  
 if (second == 0) {  
  that.setData({  
   second: "60秒倒计时结束" 
  });  
  return ;  
 }  
 var time = setTimeout(function(){  
  that.setData({  
   second: second - 1  
  });  
  countdown(that);  
 }  
 ,1000)  
}  
    
Page({  
  data: {  
    second: 60  
  },  
  onLoad: function() {  
    countdown(this);  
  }
