小程序本地存储之wx.getStorageSync和wx.removeStorageSync

小程序本地存储主要解决记录缓存，例如输入框的搜索历史记录、登录后的用户信息等，可以减少和后台的交互。

setsearchMsg:function(){
      var that=this
      if (this.data.inputValue != '') {
        //调用API向本地缓存存入数据
        var searchData = wx.getStorageSync('searchData') || []
        searchData.push(this.data.inputValue)
        wx.setStorageSync('searchData', searchData)
      }
      var searchData = wx.getStorageSync('searchData') || []
      that.setData({
        searchData: searchData
      }),
      console.log(searchData)
    },

wx.removeStorageSync('token')
