有个疑问 关于页面data 和storejs 的data

[chenfeiyu0128]

页面声明了data但是没有用，一定要在storejs 声明data吗`//index.js //获取应用实例 import store from '../../store' import create from '../../utils/create' var app = getApp() const http = require('wehttp') create(store,{ data: { islogin: false, offline: false, remind: '加载中',

刚提交了，拉取最新代码。不必须，组件自身data的也可以放在自身，不用放在store

[dntzhang]

组件的私有 data 也可以放在自身的 data 上，不用挂在 store.data 上，但是不能通过 this.update 更新，只能通过 setData

[chenfeiyu0128]

拉取了，但是还是在子页面的data上挂了数据 会被全部清空，相当去小程序现在appdata里面只有store.js的数据 而没有 store.

[dntzhang]

要把store里对应的key去掉

[dntzhang]

拉取最新，已经修复。组件和page可以有私有数据，需要setData来更新私有数据
