小程序原数组

award_result_goods:[]

生成的数据

award_result_goods:[
   {
    awardname:1,
    award:'',
    time:'2018-8-27',
    awardimg:''
   },
   {
    awardname:1,
    award:'',
    time:'2018-8-27',
    awardimg:''
   }
]

设置本地存储

 that.setData({ 
    award_one:{
      awardname: name,
      award: name,
      time: time,
      awardimg:awardimg
    }
 })
 var newarr = [that.data.award_one]; //对象转为数组
  
 this.setData({
    award_result_goods: that.data.award_result_goods.concat(newarr)  //数组链接
})
 wx.setStorageSync('award_result', JSON.stringify(that.data.award_result_goods)); //本地存储

获取本地存储

  if (wx.getStorageSync('award_result')){
      var award_result = JSON.parse(wx.getStorageSync('award_result'));
      this.setData({
        award_result_goods: award_result
      })
  }
