小程序酒店日历插件

最近在写酒店的项目,需要用到日历插件。代码如下：放在一个组件里面，在页面中直接饮用组件

const formatDate = date => {
  const year = date.getFullYear()
  const month = date.getMonth() + 1
  const day = date.getDate()
  return [year, month, day].map(formatNumber).join('-')
}

//calendarComponent.js
Component({
  properties: {
    'show_modal':{
      type:Boolean,
      value:true,
    },
    "circulateMonth":{
      type: Number,
      value: 3,
    }
  },
  observers:{
    'show_modal':function(value){
      if (!value){
       this.setData({
         scrollTop:0,
       })
    }
    }
  },
  pageLifetimes: {
    // 组件所在页面的生命周期函数
    show: function () { 
      var that = this;
      // 获取本月时间
      var nowTime = new Date();
      var year = nowTime.getFullYear();
      var month = nowTime.getMonth();
      var time = [];
      var timeArray = {};
      let circulateMonth = that.data.circulateMonth
      // 循环6个月的数据
      for (var i = 0; i < circulateMonth; i++) {
        year = month + 1 > 12 ? year + 1 : year;
        month = month + 1 > 12 ? 1 : month + 1;
        // 每个月的数据
        time = that.dataInit(year, month);
        // 接收数据
        timeArray[year + '年' + (month < 10 ? '0' + month : month) + '月'] = time;
      };
      that.setData({
        calendar: timeArray,

    },
