购物车vue项目代码

物车Vue项目代码需要实现以下功能：
1. 商品列表展示
2. 加入购物车功能
3. 购物车展示
4. 购物车商品数量修改
5. 购物车商品删除
6. 结算功能

以下是购物车Vue项目代码的实现步骤：
1. 创建Vue项目并安装Vue-router和Vuex插件
2. 创建商品列表组件List.vue，实现商品列表展示和加入购物车功能
3. 创建购物车组件Check.vue，实现购物车展示、商品数量修改和删除功能
4. 创建路由组件Product.vue和Home.vue，分别用于商品详情页和首页
5. 在App.vue中引入组件和路由，并设置路由路径
6. 创建Vuex store.js文件，实现购物车数据的存储和管理
7. 在base.scss中设置基础样式

以下是购物车Vue项目代码的完整代码：

  render: h => h(App)
}).$mount('#app')

（2） Router.js

import Vue from 'vue'
import Router from 'vue-router'
import Home from './views/Home.vue'
import Product from './views/Product.vue'
import Check from './views/Check.vue'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home
    },
    {
      path: '/product/:id',
      name: 'product',
      component: Product

    addToCart(state, product) {
      let item = state.cart.find(item => item.id === product.id)
      if (item) {
        item.quantity++
      } else {
        state.cart.push({
          ...product,
          quantity: 1
        })
      }
    },
    removeFromCart(state, product) {
      let index = state.cart.findIndex(item => item.id === product.id)
      if (index !== -1) {
        state.cart.splice(index, 1)
      }
    },
    updateQuantity(state, payload) {
      let item = state.cart.find(item => item.id === payload.id)
      if (item) {
        item.quantity = payload.quantity
      }
    }
  },
  actions: {
    addToCart({ commit }, product) {
      commit('addToCart', product)
    },
    removeFromCart({ commit }, product) {
      commit('removeFromCart', product)
    },
    updateQuantity({ commit }, payload) {
      commit('updateQuantity', payload)
    }
  },
