shopping

vue + vue-router + vuex实现电商网站

效果展示

install

• 下载代码: git clone https://github.com/chenchangyuan/shopping.git
• 安装依赖: npm install

• 启动项目: npm run dev

  运行环境: node v9.11.1 npm 5.6.0

需求分析

1. 登录页面、商品列表页（网站首页）、购物车页（实现结算）、商品详情页
2. 可按颜色、品牌对商品进行筛选，单击选中，再次点击取消
3. 根据价格进行升序降序、销量降序排列
4. 商品列表显示图片、名称、销量、颜色、单价
5. 实时显示购物车数量（商品类别数）
6. 购物车页面实现商品总价、总数进行结算，优惠券打折

数据存储 & 数据处理

• product.js存放商品数据（生产环境需通过接口调用获取数据）

{id: 1,name: 'AirPods',brand: 'Apple',image: '/src/images/airPods.jpg',imageDetail: '/src/images/airPods_detail.jpg',sales: 10000,cost: 1288,color: '白色'
},

• window.localStorage实现数据存储与验证

let username = window.localStorage.getItem('username');
let password = window.localStorage.getItem('password');
if(!util.trim(this.username) || !util.trim(this.username) ){window.alert('账号或密码不能为空');return;
}
if(username === this.username && password === this.password){this.login = false;window.localStorage.setItem('loginStatus', 'login');this.$store.commit('getUser', this.username);window.alert('登陆成功，确定进入网站首页');window.location.href = '/list';
}else{window.alert('账号或密码错误');
}

数据过滤与排序处理

filteredAndOrderedList(){//拷贝原数组let list = [...this.list];//品牌过滤if(this.filterBrand !== ''){list = list.filter(item => item.brand === this.filterBrand);}//颜色过滤if(this.filterColor !== ''){list = list.filter(item => item.color === this.filterColor);}//排序if(this.order !== ''){if(this.order === 'sales'){list = list.sort((a, b) => b.sales - a.sales);}else if(this.order === 'cost-desc'){list = list.sort((a, b) => b.cost - a.cost);}else if(this.order === 'cost-asc'){list = list.sort((a, b) => a.cost - b.cost);}}return list;
}

实时显示应付总额与商品数

//购物车商品总数
countAll(){let count = 0;this.cartList.forEach(item => {count += item.count;});return count;
},
//购物车商品总价
costAll(){let cost = 0;this.cartList.forEach(item => {cost += this.productDictList[item.id].cost * item.count;});return cost;
}

购物车结算处理

//通知Vuex,完成下单
handleOrder(){this.$store.dispatch('buy').then(() => {window.alert('购买成功');})
},

vue-router & vuex

vue-router路由管理/src/views/目录下的vue组件进行设置，router-views挂载所有路由，登录界面与商品列表页面之间header做隐藏显示处理，登录状态下刷新页面跳转至列表页，其他页面设置默认跳转

跳转处理

const router = new VueRouter(RouterConfig);//跳转前设置title
router.beforeEach((to, from, next) => {window.document.title = to.meta.title;next();
});
//跳转后设置scroll为原点
router.afterEach((to, from, next) => {window.scrollTo(0, 0);
});

routers配置

//商品列表路由配置
const routers = [{path: '/list',meta: {title: '商品列表'},component: (resolve) => require(['./views/list.vue'], resolve)},{path: '/product/:id',meta: {title: '商品详情'},component: (resolve) => require(['./views/product.vue'], resolve)},{path: '/cart',meta: {title: '购物车'},component: (resolve) => require(['./views/cart.vue'], resolve)},{path: '/login/:loginStatus',meta: {title: '购物车'},component: (resolve) => require(['./views/login.vue'], resolve)},{path: '*',redirect: '/login/login'}
];
export default routers;

vuex状态管理，各组件共享数据在state中设置，mutation实现数据同步，action异步加载

//配置Vuex状态管理
const store = new Vuex.Store({state: {//商品列表信息productList: [],//购物车数据，数组形式，数据元素为对象（商品id，购买数量count）cartList: [],//当前用户账号username: window.localStorage.getItem('username'),//登录状态loginStatus: !!window.localStorage.getItem('loginStatus'),},getters: {//品牌、颜色筛选brands: state => {const brands = state.productList.map(item => item.brand);return util.getFilterArray(brands);},colors: state => {const colors = state.productList.map(item => item.color);return util.getFilterArray(colors);}},//mutations只能以同步方式mutations: {//添加商品列表setProductList(state, data){state.productList = data;},//添加购物车addCart(state, id){const isAdded = state.cartList.find(item => item.id === id);//如果不存在设置购物车为1，存在count++if(isAdded){isAdded.count++;}else{state.cartList.push({id: id,count: 1})}},//修改购物车商品数量editCartCount(state, payload){const product = state.cartList.find(item => item.id === payload.id);product.count += payload.count;},//删除购物车商品deleteCart(state, id){const index = state.cartList.findIndex(item => item.id === id);state.cartList.splice(index, 1)},//清空购物车emptyCart(state){state.cartList = [];},getUser(state, username){console.log('username',username)state.username = username;},getLoginStatus(state, flag){state.loginStatus = flag;}},actions: {//异步请求商品列表，暂且使用setTimeoutgetProductList(context){setTimeout(() => {context.commit('setProductList', product_data)}, 500);},//购买buy(context){//生产环境使用ajax请求服务端响应后再清空购物车return new Promise(resolve => {setTimeout(() => {context.commit('emptyCart');resolve();}, 500);});},}
});
