微信小程序动态显示项目倒计时效果

<p><block wx:if="{{total_micro_second<=0}}">剩余时间：已经截止</block><block wx:if="{{clock!='已经截止'}}">剩余时间：{{clock}}</block></p>

function countdown(that) { var EndTime = that.data.end_time || []; var NowTime = new Date().getTime(); var total_micro_second = EndTime - NowTime || []; console.log('剩余时间：' + total_micro_second);  // 渲染倒计时时钟  that.setData({  clock: dateformat(total_micro_second)  });  if (total_micro_second <= 0) {  that.setData({   clock: "已经截止"  });  //return;  }  setTimeout(function () {  total_micro_second -= 1000;  countdown(that);  }  , 1000) } // 时间格式化输出，如11:03 25:19 每1s都会调用一次 function dateformat(micro_second) {  // 总秒数  var second = Math.floor(micro_second / 1000);  // 天数  var day = Math.floor(second/3600/24);  // 小时  var hr = Math.floor(second/3600%24);  // 分钟  var min = Math.floor(second/60%60);  // 秒  var sec = Math.floor(second%60);  return day + "天" + hr + "小时" + min + "分钟" + sec+"秒"; }Page({ /** * 页面的初始数据 */ data: { id:'', result:[], end_time:'', clock:'' },/** * 生命周期函数--监听页面加载 */ onLoad: function (options) { var that = this; wx.request({  url: 'https://m.******.com/index.php/Home/Xiaoxxf/activity_detail?a_id='+options.id,//不含富文本html  data: {},  method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT  header: {  'Content-Type': 'application/json'  },  success: function (res) {  that.setData({   common: res.data, //一维数组，全部数据   end_time: res.data.end_time //项目截止时间，时间戳，单位毫秒  })  console.log(that.data.common);  console.log('结束时间：' + that.data.end_time);  },  fail: function (res) { },  complete: function (res) { }, }), //调用上面定义的递归函数，一秒一刷新时间 countdown(that);},
