小程序数据缓存localStorage

同步版本加Sync在storage后面

存储:

wx.setStorage({
  key:"key",
  data:"value"
})
wx.setStorage('storage', this.data.storage)

获取:

that = this; 
wx.getStorage({
      key: 'storage',
      success: function(res){
        // success
        that.setData({
          storage:res.data
        })
      }
    })

移除:

wx.removeStorage({
  key: 'storage',
  success (res) {
    console.log(res)
  }
})

清理:

wx.clearStorage()

实例:

index的 js：

//获取应用实例
var app = getApp()
Page({
  data: {
    storage:''
  },
  onLoad: function () {
    var that = this

  //获取输入值
  getInput:function(e){
    this.setData({
      storage:e.detail.value
    })
  },
  //存储输入值
  saveInput:function(){
    wx.setStorageSync('storage', this.data.storage)
  }

})

跳转页面的js：

var app = getApp();
var that;  
Page( {  
  data: {    
    storage:''
  },  
  onLoad: function(options) {  
    that = this; 
    //获取存储信息
    wx.getStorage({
      key: 'storage',
      success: function(res){
        // success
        that.setData({
          storage:res.data
        })
      }
    })
  }
})
