本文实例为大家分享了vuex实现购物车功能的具体代码，供大家参考，具体内容如下

先看效果:

代码：

<template> <div class="Home"> <h1>vuex购物车案例</h1> <add-from></add-from> <shop-cart></shop-cart> </div></template><script>import AddFrom from './Add.vue'import ShopCart from './ShopCart.vue'// @ is an alias to /src// import HelloWorld from '@/components/HelloWorld.vue'export default { name: 'Home', components: { AddFrom, ShopCart },};</script><style>table { width: 800px; margin: 0 auto; border: 1px solid #ccc; border-spacing: 0;}tbody th,tbody td { border: 1px solid #ccc; text-align: center;}h1{ text-align: center;}.add{ width: 800px; margin: 0 auto;}</style>

父组件

<template> <div class="add"> <div class="from-group"> <label for="">商品编号</label> <input type="text" v-model="shop.id" placeholder="请输入商品编号"> </div> <div class="from-group"> <label for="">商品名称</label> <input type="text" v-model="shop.name" placeholder="请输入商品名称"> </div> <div class="from-group"> <label for="">商品价格</label> <input type="text" v-model="shop.price" placeholder="请输入商品价格"> </div> <div class="from-group"> <label for="">商品数量</label> <input type="text" v-model="shop.count" placeholder="请输入商品数量"> </div> <div class="from-group"> <button @click="add">添加商品</button> </div> </div></template><script>export default { name: 'add', data() { return { shop:{} }; }, methods:{ add(){ this.$store.dispatch("addShopList",this.shop) this.shop = { id:"", name:"", price:"", count:"" } } }};</script><style scoped> .add{ width: 800px; text-align: center; }</style>

```bash

<template> <div class="Shop-Cart"> <table> <thead border> <tr> <th>商品编号</th> <th>商品名称</th> <th>商品价格</th> <th>商品数量</th> <th>小计</th> <th>操作</th> </tr> </thead> <tbody v-if="shop.length > 0"> <tr v-for="(i, e) in shop" :key="e"> <td>{{ i.id }}</td> <td>{{ i.name }}</td> <td>{{ i.price }}</td> <td> <button @click="add(e)">+</button> <input type="text" v-model="i.count" /> <button @click="delet(e)">-</button> </td> <td>￥{{ i.price * i.count }}</td> <td><button @click="del(e)">删除</button></td> </tr> </tbody> <tfoot> <tr> <td colspan="6" align="right">总计：{{ total }}</td> <button @click="clear">清除购物车</button> </tr> </tfoot> </table> </div></template><script>export default { name: 'Shop-Cart', components: {}, data() { return {}; }, computed: { shop() { return this.$store.getters.getlist; }, total() { return this.$store.getters.getShopTotal; } }, methods: { del(e) { // this.$store.dispatch() this.$store.dispatch('remoteList', e); }, add(e) { this.$store.dispatch('addList', e); }, delet(e) { this.$store.dispatch('deleteList', e); }, clear() { this.$store.dispatch('clearList', []); } }};</script>

vuex组件

import Vue from 'vue'import Vuex from 'vuex'Vue.use(Vuex)export default new Vuex.Store({ state: { list: [{ id: 1, name: "哇哈哈", price: 3, count: 0 }, { id: 2, name: "哇哈", price: 3, count: 0 } ] }, getters: { //获取购物车数据 getlist(state) { return state.list }, //商品的总价 getShopTotal(state,index) { let result = 0; state.list.forEach((item, index) => { result += item.price * item.count }) return result }, }, mutations: { //删除购物车单个数据 remoteList(state,index) { state.list.splice(index, 1); console.log("aaa",state) }, //商品数量增加 addList(state, index) { state.list[index].count++; }, //商品数量减少 deleteList(state, index) { state.list[index].count--; if(state.list[index].count<=0){ state.list[index].count = 0 return ; } }, //清除购物车 clearList(state, arr) { state.list = arr }, addShopList(state,shop){ state.list.push(shop) } }, //使用actions调用mutations方法 actions: { remoteList({ commit }, index) { commit("remoteList", index) }, addList({ commit }, index) { commit("addList", index) }, deleteList({ commit }, index) { commit("deleteList", index) }, clearList({ commit }, arr) { commit("clearList", arr) }, addShopList({commit},shop){ commit("addShopList",shop) } }, modules: {}})
