微信小程序开发中数据存储、参数传递和数据缓存的介绍

wx.navigateTo({ url: "../newpage/newpage?infofromindex=" + this.data.infofromindex, });

try { wx.setStorageSync('infofrominput', this.data.infofrominput) } catch (e) { }

//获取 wx.getStorage({ key: 'infofrominput', success: function (res) { _this.setData({ infofromstorage: res.data, }) } })

//index.js //获取应用实例 var app = getApp() Page({ data: { info: app.data.info, infofromindex: '来自index.js的信息', infofrominput: '' }, onLoad: function () { }, //跳转到新页面 gotonewpage: function () { wx.navigateTo({ url: "../newpage/newpage?infofromindex=" + this.data.infofromindex, }); }, //获取输入值 searchInputEvent: function (e) { console.log(e.detail.value) this.setData({ infofrominput: e.detail.value }) }, //保存参数 saveinput: function () { try { wx.setStorageSync('infofrominput', this.data.infofrominput) } catch (e) { } } })

  跳转  存入Storage 

//newpage.js //获取应用实例 var app = getApp() Page({ data: { infofromapp: app.data.infofromapp, infofromindex: '', infofromstorage: '', }, onLoad: function (options) { var _this = this; var infofromindex = options.infofromindex; this.setData({ infofromindex: infofromindex }) //获取 wx.getStorage({ key: 'infofrominput', success: function (res) { _this.setData({ infofromstorage: res.data, }) } }) } })

 infofromapp:{{infofromapp}} infofromindex:{{infofromindex}} infofromstorage:{{infofromstorage}}

//app.js App({ data: { infofromapp: '来自APP.js的信息' }, onLaunch: function () { } })
