+## 页面通信
+该示例为小程序间的页面通讯，利用 vuex 实现
+
+在 `mpvue`框架中使用 `vuex` 与在 `vue` 中使用是一样的体验，
+
+1.建立相关的目录结构
+
+![vuex01](_img/vuex01.png)
+
+2.在 src/main.js 中将 store 挂载到 vue 原型下面
+
+``` javascript
+Vue.prototype.$store = store;
+```
+
+3.在页面中通过 mapGetters 和 mapMutations 使用 state
+
+``` javascript
+  methods: {
+    ...mapMutations({
+      setMpvueInfoVuex: 'SET_MPVUEINFO'
+    })
+  },
+
+  computed: {
+    ...mapGetters([
+      'mpvueInfo'
+    ])
+  }
+```
+
+**效果**
