1)mutations.js代码如下
const mutations={ add(state){ state.count++ }, reduce(state){ state.count-- } }
2)在button中,通过commit直接调用。
<button @click="$store.commit(‘add‘)">+</button> <button @click="$store.commit(‘reduce‘)">-</button>
放在组件home.vue中案例代码
<template> <div class="Home"> <button @click="$store.commit(‘add‘)">+</button> <button @click="$store.commit(‘reduce‘)">-</button> <p>引用state选项一个变量:{{count}}</p> </div> </template> <script> export default { name: ‘Home‘, data () { return { msg: ‘Home.vue 组件‘ } }, computed: { // 调用是vuex,state选项文件rootState.js中声明变量 count () { console.log(‘this结构:‘ + this.$store.state.count) return this.$store.state.count } } } </script>
