先是儲存wx.setStorage

Page({
  data: {
    testnum:""//設定測試引數
  },
  test:function(){
    var Num = this.data.testnum;
    wx.setStorage({//儲存到本地
      key:"testNum",
      data:Num
    })
  }
})

另一頁要獲取testnum的方法

①wx.getStorage

Page({
  data: {
    testnum:""//設定測試引數
  },
onLoad:function(option){
    var that = this,
    wx.getStorage({//獲取本地快取
      key:"testNum",
      success:function(res){
        that.setData({
          testnum:res.data
        });
      },
    })
  }
})
 

②wx.getStorageSync

Page({
  data: {
    testnum:""//設定測試引數
  },
  onLoad:function(option){
    var num = wx.getStorageSync('testNum');//wx.getStorageSync(key)，獲取本地快取
    this.setData({
      testnum:testnum
    })；
  }
})
