微信小程序怎样处理页面缓存

微信小程序处理页面缓存的方法：

根据当前时间作为判断根据，缓存数据，代码：

    Page({
     data: {
     },
     onLoad: function () {
      //this.getNowTime()
      if(wx.getStorageSync("loaction_time")==this.getNowTime()){
       //读取缓存
       console.log("缓存地址");
        var datevalue=wx.getStorageSync("loaction");
        console.log(datevalue)
      }else{
       wx.removeStorageSync("loaction");
       //要求地址
       console.log("要求地址");
       var loactionname="bs";
       wx.setStorageSync("loaction",loactionname);
       wx.setStorageSync("loaction_time",this.getNowTime());
       var datevalue=wx.getStorageSync("loaction");
       console.log(datevalue)
      }
     },getNowTime: function() {
      var now = new Date();
      var year = now.getFullYear();
      var month = now.getMonth() + 1;
      var day = now.getDate();
      if(month < 10) {
       month = '0' + month;
      };
      if(day < 10) {
       day = '0' + day;
      };
      // 如果需要时分秒，就放开
      var h = now.getHours();
      var m = now.getMinutes();
      var s = now.getSeconds();
      //var formatDate = year + '-' + month + '-' + day + ' ' + h + ':' + m + ':' + s;
      var formatDate = year + '-' + month + '-' + day;
      //console.log('当前时间',formatDate)
      return formatDate;
     }
    })
