vue是前端轻量级MVVM框架,入门门槛相对较低,今天用Vue做一个购物车实例,发表以便记录
首先,还是先把布局写好,和引入vue,准备vue实例,这个不多说,代码如下

然后准备下列表数据,根据下面表格的箭头
productList:[ { 'pro_name': '【斯文】甘油 | 丙三醇',//产品名称 'pro_brand': 'skc',//品牌名称 'pro_place': '韩国',//产地 'pro_purity': '99.7%',//规格 'pro_min': "215千克",//最小起订量 'pro_depot': '上海仓海仓储',//所在仓库 'pro_num': 3,//数量 'pro_img': '../../images/ucenter/testimg.jpg',//图片链接 'pro_price': 800//单价 } ]
准备了这么多,大家可能想到,还缺少一个,就是记录产品是否有选中,但是这个字段,虽然可以在上面那里加,但是意义不大,比如在平常项目那里!后台的数据不会这样返回,数据库也不会有这个字段,这个字段应该是自己添加的。代码如下
new Vue({ el:'#shopping-cart', data:{ productList:[ { 'pro_name': '【斯文】甘油 | 丙三醇',//产品名称 'pro_brand': 'skc',//品牌名称 'pro_place': '韩国',//产地 'pro_purity': '99.7%',//规格 'pro_min': "215千克",//最小起订量 'pro_depot': '上海仓海仓储',//所在仓库 'pro_num': 3,//数量 'pro_img': '../../images/ucenter/testimg.jpg',//图片链接 'pro_price': 800//单价 } ] }, computed: {}, methods:{ }, mounted:function () { //为productList添加select(是否选中)字段,初始值为true var _this=this; //为productList添加select(是否选中)字段,初始值为true this.productList.map(function (item) { _this.$set(item, 'select', true); }) //要像上面这样写双向绑定才能起效,下面的写法是有问题的,双向绑定不起效的! //this.productList.map(function (item) {item.select=true}) } })
步骤一、点击增加和减少按钮(箭头指向地方),所属列的金额改变(红框地方)要先把列表的数据给铺出来。利用v-for指令。代码如下
<tr v-for="item in productList"> <td class="td-check"><span class="check-span"></span></td> <td class="td-product"><img :src="item.pro_img" width="98" height="98"> <div class="product-info"> <h6>{{item.pro_name}}</h6> <p>品牌:{{item.pro_brand}} 产地:{{item.pro_place}}</p> <p>规格/纯度:{{item.pro_purity}} 起定量:{{item.pro_min}}</p> <p>配送仓储:{{item.pro_depot}}</p> </div> <div class="clearfix"></div> </td> <td class="td-num"> <div class="product-num"> <a href="javascript:;" class="num-reduce num-do fl" @click="item.pro_num--"><span></span></a> <input type="text" class="num-input" v-model="item.pro_num"> <a href="javascript:;" class="num-add num-do fr" @click="item.pro_num++"><span></span></a> </div> </td> <td class="td-price"> <p class="red-text">¥<span class="price-text">{{item.pro_price.toFixed(2)}}</span></p> </td> <td class="td-total"> <p class="red-text">¥<span class="total-text">{{item.pro_price*item.pro_num}}</span>.00</p> </td> <td class="td-do"><a href="javascript:;" class="product-delect">删除</a></td> </tr>
这两个按钮的功能已经实现了,后面的金额也会发生变化!是不是感到很惊喜!其实这里没什么特别的,就是因为输入框利用v-model绑定了数量(pro_num
),然后两个按钮分别添加了事件@click="item.pro_num--"
和@click="item.pro_num++"
。
点击所属列选择按钮(箭头指向地方),总计的金额(红框地方)和已选产品的列数(蓝框地方)和全选(黄框地方)会改变(如果已经全选了,全选按钮自动变成全选,如果没有全选,全选按钮,自动取消全选)!
首先,选择与取消选择,在这里只有两个操作(其实只有一个:改变这条记录的select
字段)。
<td class="td-check"><span class="check-span" @click="item.select=!item.select" :class="{'check-true':item.select}"></span></td>
其实就是等于添加了@click="item.select=!item.select" :class="{'check-true':item.select}"
这里。点击这个,这条数据的select
字段就取反(true->false或者false->true)。然后:class="{'check-true':item.select}"
,就会根据这条数据的select
字段进行判断,是否添加check-true
类名,如果select
字段为true,就添加类名
全选按钮:
这里用一个computed(计算属性)就好。
html
<div class="td-check fl"><span class="check-span fl check-all" :class="{'check-true':isSelectAll}"></span>全选</div>
js
computed: { isSelectAll:function(){ //如果productList中每一条数据的select都为true,返回true,否则返回false; return this.productList.every(function (val) { return val.select}); } }
就是计算属性中,定义的isSelectAll依赖productList。只要productList改变,isSelectAll的返回值就会改变,然后:class="{'check-true':isSelectAll}"
根绝isSelectAll返回值是否添加'check-true'
类名,显示对应的样式!
这里的多少件产品和总价,也是使用计算属性
html
<p class="fr product-total">¥<span>{{getTotal.totalPrice}}</span></p> <p class="fr check-num"><span>{{getTotal.totalNum}}</span>件商品总计(不含运费):</p>
js
computed: { //检测是否全选 isSelectAll:function(){ //如果productList中每一条数据的select都为true,返回true,否则返回false; return this.productList.every(function (val) { return val.select}); }, //获取总价和产品总件数 getTotal:function(){ //获取productList中select为true的数据。 var _proList=this.productList.filter(function (val) { return val.select}),totalPrice=0; for(var i=0,len=_proList.length;i<len;i++){ //总价累加 totalPrice+=_proList[i].pro_num*_proList[i].pro_price; } //选择产品的件数就是_proList.length,总价就是totalPrice return {totalNum:_proList.length,totalPrice:totalPrice} } },
点击全选按钮(箭头指向部分),会自动的对产品进行全选或者取消全选,下面的总计也会发生改变
做到这一步,大家应该知道,全选或者取消全选,就是改变记录的select
。但是怎么知道现在的列表有没有全选呢?这个很贱,不需要在操作函数(全选与取消全选函数)里面遍历,大家应该还记得第二步的计算属性isSelectAll
(为true就是全选,否则不是全选),把这个传进操作函数就好,然后操作函数,根据参数,决定执行全选,还是取消全选操作。代码如下!
html
<div class="td-check fl"><span class="check-span fl check-all" :class="{'check-true':isSelectAll}" @click="selectProduct(isSelectAll)"></span>全选</div>
js
methods: { //全选与取消全选 selectProduct:function(_isSelect){ //遍历productList,全部取反 for (var i = 0, len = this.productList.length; i < len; i++) { this.productList[i].select = !_isSelect; } } },
点击删除产品,会删除已经选中的,全选按钮和下面的总计,都会变化!点击每条记录后面的删除,会删除当前的这条记录。全选按钮和下面的总计,也都会变化!
首先,点击删除产品,删除已经选中。这个大家知道了怎么做了!就是遍历productList,如果哪条记录的select为true,就删除。
然后,点击每条记录后面的删除,删除当前的这条记录。这个在html遍历productList的时候。顺便带上索引,然后把索引当成参数,传进操作函数,然后根据索引参数,删除productList的哪一条记录。即可实现!代码如下!
html
<!--遍历的时候带上索引--> <tr v-for="(item,index) in productList"> <td class="td-check"><span class="check-span" @click="item.select=!item.select" :class="{'check-true':item.select}"></span></td> <td class="td-product"><img :src="item.pro_img" width="98" height="98"> <div class="product-info"> <h6>{{item.pro_name}}</h6> <p>品牌:{{item.pro_brand}} 产地:{{item.pro_place}}</p> <p>规格/纯度:{{item.pro_purity}} 起定量:{{item.pro_min}}</p> <p>配送仓储:{{item.pro_depot}}</p> </div> <div class="clearfix"></div> </td> <td class="td-num"> <div class="product-num"> <a href="javascript:;" class="num-reduce num-do fl" @click="item.pro_num--"><span></span></a> <input type="text" class="num-input" v-model="item.pro_num"> <a href="javascript:;" class="num-add num-do fr" @click="item.pro_num++"><span></span></a> </div> </td> <td class="td-price"> <p class="red-text">¥<span class="price-text">{{item.pro_price.toFixed(2)}}</span></p> </td> <td class="td-total"> <p class="red-text">¥<span class="total-text">{{item.pro_price*item.pro_num}}</span>.00</p> </td> <td class="td-do"><a href="javascript:;" class="product-delect" @click="deleteOneProduct(index)">删除</a></td> </tr> ... <a class="delect-product" href="javascript:;" @click="deleteProduct"><span></span>删除所选商品</a>
js
//删除已经选中(select=true)的产品 deleteProduct:function () { this.productList=this.productList.filter(function (item) {return !item.select}) }, //删除单条产品 deleteOneProduct:function (index) { //根据索引删除productList的记录 this.productList.splice(index,1); },
