实现对商品的增加、删除、数量的修改功能
删除商品可选择直接删除当前商品、删除选中商品、删除所有商品
添加商品时会自动添加日期字段
商品的属性
goods : {
id : '',
name : '',
price : '',
num : '',
type : '',
addDate : ''
}

商品头部数据域
data : { imgUrl : '../res/images/', imgName : 'logo.png' }
商品头部样式
.container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; }
<!--有logo和title--> <div class="header"> <img :src="imgUrl + imgName" class="logo" height="80px" /> <h1 class="title">Gary_商品管理</h1> </div>
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Gary商品管理</title> <script type="text/javascript" src="../js/vue.js" ></script> <script> window.onload = () => { let vm = new Vue({ el : '.container', data : { imgUrl : '../res/images/', imgName : 'logo.png' }, methods : { } }); } </script> <style type="text/css"> .container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; } </style> </head> <body> <div class="container"> <!--有logo和title--> <div class="header"> <img :src="imgUrl + imgName" class="logo" height="80px" /> <h1 class="title">Gary_商品管理</h1> </div> <!--输入部分input--> <div class="form-warp"></div> <!--显示 表格--> <div class="table-wrap"></div> </div> </body> </html>
添加商品的部分属性
data : { imgUrl : '../res/images/', imgName : 'logo.png', goods : { id : '', name : '', price : '', num : '', type : '', }, goodsType : ['零食', '电子产品', '生活用品'] }
<!--输入部分input--> <div class="form-warp"></div> <div class = "title">添加商品</div> <div class="content"> 商品编号：<input type="text" placeholder="请输入商品编号" v-model="goods.id"/><br /> 商品名称：<input type="text" placeholder="请输入商品名称" v-model="goods.name"/><br /> 商品价格：<input type="text" placeholder="请输入商品价格" v-model="goods.price"/><br /> 商品数量：<input type="text" placeholder="请输入商品数量" v-model="goods.num"/><br /> 商品类型：<select v-model="goods.type"> <option value=""> -- 选择商品类型 --</option> <option v-for="type in goodsType">{{type}}</option> </select> </div>

二、添加商品
在Vue数据域中添加商品实例
goodsArray : [ {id : '001', name : '可乐', price : 10, num : 10, type : '零食', addDate : '2019-02-23'}, {id : '002', name : '手机', price : 1000, num : 20, type : '电子产品', addDate : '2019-02-24'}, {id : '003', name : '毛巾', price : 5, num : 30, type : '生活用品', addDate : '2019-02-25'}
在body中添加列出商品详情
<table border="1" align="center" cellspacing="" cellpadding=""> <tr> <th>序号</th> <th>编号</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>类型</th> </tr> <tr v-for="(item, index) in goodsArray" :key="item.id"> <td>{{index}}</td> <td>{{item.id}}</td> <td>{{item.name}}</td> <td>{{item.price}}</td> <td>{{item.num}}</td> <td>{{item.type}}</td> </tr> </table>
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Gary商品管理</title> <script type="text/javascript" src="../js/vue.js" ></script> <script> window.onload = () => { let vm = new Vue({ el : '.container', data : { imgUrl : '../res/images/', imgName : 'logo.png', goods : { id : '', name : '', price : '', num : '', type : '' }, goodsType : ['零食', '电子产品', '生活用品'], goodsArray : [ {id : '001', name : '可乐', price : 10, num : 10, type : '零食', addDate : '2019-02-23'}, {id : '002', name : '手机', price : 1000, num : 20, type : '电子产品', addDate : '2019-02-24'}, {id : '003', name : '毛巾', price : 5, num : 30, type : '生活用品', addDate : '2019-02-25'} ] }, methods : { } }); } </script> <style type="text/css"> .container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; } </style> </head> <body> <div class="container"> <!--有logo和title--> <div class="header"> <img :src="imgUrl + imgName" class="logo" height="80px" /> <h1 class="title">Gary_商品管理</h1> </div> <!--输入部分input--> <div class="form-warp"></div> <div class = "title">添加商品</div> <div class="content"> 商品编号：<input type="text" placeholder="请输入商品编号" v-model="goods.id"/><br /> 商品名称：<input type="text" placeholder="请输入商品名称" v-model="goods.name"/><br /> 商品价格：<input type="text" placeholder="请输入商品价格" v-model="goods.price"/><br /> 商品数量：<input type="text" placeholder="请输入商品数量" v-model="goods.num"/><br /> 商品类型：<select v-model="goods.type"> <option value=""> -- 选择商品类型 --</option> <option v-for="type in goodsType">{{type}}</option> </select> </div> <div class="form-btn"></div> <button>确认添加</button> <button>重置信息</button> <!--显示 表格--> <div class="table-wrap"> <div class="title">商品列表</div> <div class="content"> <table border="1" align="center" cellspacing="" cellpadding=""> <tr> <th>序号</th> <th>编号</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>类型</th> </tr> <tr v-for="(item, index) in goodsArray" :key="item.id"> <td>{{index}}</td> <td>{{item.id}}</td> <td>{{item.name}}</td> <td>{{item.price}}</td> <td>{{item.num}}</td> <td>{{item.type}}</td> </tr> </table> </div> </div> </div> </body> </html>
给"确认添加"和"重置信息"绑定事件响应
methods : { addGoods(){ this.goodsArray.push(this.goods); this.goods = {}; } }
<button @click="addGoods">确认添加</button> <button @click="goods = {}">重置信息</button>
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Gary商品管理</title> <script type="text/javascript" src="../js/vue.js" ></script> <script> window.onload = () => { let vm = new Vue({ el : '.container', data : { imgUrl : '../res/images/', imgName : 'logo.png', goods : { id : '', name : '', price : '', num : '', type : '' }, goodsType : ['零食', '电子产品', '生活用品'], goodsArray : [ {id : '001', name : '可乐', price : 10, num : 10, type : '零食', addDate : '2019-02-23'}, {id : '002', name : '手机', price : 1000, num : 20, type : '电子产品', addDate : '2019-02-24'}, {id : '003', name : '毛巾', price : 5, num : 30, type : '生活用品', addDate : '2019-02-25'} ] }, methods : { addGoods(){ this.goodsArray.push(this.goods); this.goods = {}; } } }); } </script> <style type="text/css"> .container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; } </style> </head> <body> <div class="container"> <!--有logo和title--> <div class="header"> <img :src="imgUrl + imgName" class="logo" height="80px" /> <h1 class="title">Gary_商品管理</h1> </div> <!--输入部分input--> <div class="form-warp"></div> <div class = "title">添加商品</div> <div class="content"> 商品编号：<input type="text" placeholder="请输入商品编号" v-model="goods.id"/><br /> 商品名称：<input type="text" placeholder="请输入商品名称" v-model="goods.name"/><br /> 商品价格：<input type="text" placeholder="请输入商品价格" v-model="goods.price"/><br /> 商品数量：<input type="text" placeholder="请输入商品数量" v-model="goods.num"/><br /> 商品类型：<select v-model="goods.type"> <option value=""> -- 选择商品类型 --</option> <option v-for="type in goodsType">{{type}}</option> </select> </div> <div class="form-btn"></div> <button @click="addGoods">确认添加</button> <button @click="goods = {}">重置信息</button> <!--显示 表格--> <div class="table-wrap"> <div class="title">商品列表</div> <div class="content"> <table border="1" align="center" cellspacing="" cellpadding=""> <tr> <th>序号</th> <th>编号</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>类型</th> </tr> <tr v-for="(item, index) in goodsArray" :key="item.id"> <td>{{index}}</td> <td>{{item.id}}</td> <td>{{item.name}}</td> <td>{{item.price}}</td> <td>{{item.num}}</td> <td>{{item.type}}</td> </tr> </table> </div> </div> </div> </body> </html>
三、给项目添加样式
直接在<style type="text/css"></style>中为项目添加样式
<style type="text/css"> .container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; } .header{ margin: 10px; border: 1px solid gray; } .header .title{ color: rgb(53, 73, 93); background: rgb(65, 184, 131); } .logo{ position: relative; top: 12px; } .form-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .form-warp .content{ line-height: 35px; } .form-warp input{ width: 150px; height: 18px; } .form-warp select{ width: 154px; height: 24px; } .sub-title{ color: rgb(65, 184, 131); background: rgb(53, 73, 93); } .table-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .table-warp th{ width: 80px; color: #FFF; background-color: rgb(53, 73, 93); } .table-warp a{ text-decoration: none; } .clear-btn{ text-align: right; padding-right: 10px; } .fontColor{ color: gray; } .myBackgounrdColor{ background: rgb(65, 184, 131); } .myFontSize{ font-size: 200px; } </style>
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Gary商品管理</title> <script type="text/javascript" src="../js/vue.js" ></script> <script> window.onload = () => { let vm = new Vue({ el : '.container', data : { imgUrl : '../res/images/', imgName : 'logo.png', goods : { id : '', name : '', price : '', num : '', type : '' }, goodsType : ['零食', '电子产品', '生活用品'], goodsArray : [ {id : '001', name : '可乐', price : 10, num : 10, type : '零食', addDate : '2019-02-23'}, {id : '002', name : '手机', price : 1000, num : 20, type : '电子产品', addDate : '2019-02-24'}, {id : '003', name : '毛巾', price : 5, num : 30, type : '生活用品', addDate : '2019-02-25'} ] }, methods : { addGoods(){ this.goodsArray.push(this.goods); this.goods = {}; } } }); } </script> <style type="text/css"> .container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; } .header{ margin: 10px; border: 1px solid gray; } .header .title{ color: rgb(53, 73, 93); background: rgb(65, 184, 131); } .logo{ position: relative; top: 12px; } .form-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .form-warp .content{ line-height: 35px; } .form-warp input{ width: 150px; height: 18px; } .form-warp select{ width: 154px; height: 24px; } .sub-title{ color: rgb(65, 184, 131); background: rgb(53, 73, 93); } .table-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .table-warp th{ width: 80px; color: #FFF; background-color: rgb(53, 73, 93); } .table-warp a{ text-decoration: none; } .clear-btn{ text-align: right; padding-right: 10px; } .fontColor{ color: gray; } .myBackgounrdColor{ background: rgb(65, 184, 131); } .myFontSize{ font-size: 200px; } </style> </head> <body> <div class="container"> <!--有logo和title--> <div class="header"> <img :src="imgUrl + imgName" class="logo" height="80px" /> <h1 class="title">Gary_商品管理</h1> </div> <!--输入部分input--> <div class="form-warp"></div> <div class = "title">添加商品</div> <div class="content"> 商品编号：<input type="text" placeholder="请输入商品编号" v-model="goods.id"/><br /> 商品名称：<input type="text" placeholder="请输入商品名称" v-model="goods.name"/><br /> 商品价格：<input type="text" placeholder="请输入商品价格" v-model="goods.price"/><br /> 商品数量：<input type="text" placeholder="请输入商品数量" v-model="goods.num"/><br /> 商品类型：<select v-model="goods.type"> <option value=""> -- 选择商品类型 --</option> <option v-for="type in goodsType">{{type}}</option> </select> </div> <div class="form-btn"></div> <button @click="addGoods">确认添加</button> <button @click="goods = {}">重置信息</button> <!--显示 表格--> <div class="table-wrap"> <div class="title">商品列表</div> <div class="content"> <table border="1" align="center" cellspacing="" cellpadding=""> <tr> <th>序号</th> <th>编号</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>类型</th> </tr> <tr v-for="(item, index) in goodsArray" :key="item.id"> <td>{{index}}</td> <td>{{item.id}}</td> <td>{{item.name}}</td> <td>{{item.price}}</td> <td>{{item.num}}</td> <td>{{item.type}}</td> </tr> </table> </div> </div> </div> </body> </html>
四、删除商品与提示
添加删除商品button放入表单个中
<table border="1" align="center" cellspacing="" cellpadding=""> <tr> <th>序号</th> <th>编号</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>类型</th> <th>删除</th> </tr> <tr> <td :colspan="colNum" height="150px" v-show="goodsArray.length <= 0">暂无商品</td> </tr> <tr v-for="(item, index) in goodsArray" :key="item.id"> <td>{{index}}</td> <td>{{item.id}}</td> <td>{{item.name}}</td> <td>{{item.price}}</td> <td>{{item.num}}</td> <td>{{item.type}}</td> <td> <button @click="delGoods(index)">删除</button> </td> </tr> </table>
添加清空全部商品按钮点击控件
使用@click.prevent可以阻止删除<a>标签默认跳转事件，使用v-show="goodsArray.length > 0判断当商品个数大于0的时候才将次链接显示出来
<div> <a href="#" @click.prevent="clearGoodsArray" v-show="goodsArray.length > 0">清空全部</a> </div>
添加绑定删除单个商品和全部商品的函数
methods : { addGoods(){ this.goodsArray.push(this.goods); this.goods = {}; }, delGoods(index){ this.goodsArray.splice(index, 1); }, clearGoodsArray(){ this.goodsArray = []; } }
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Gary商品管理</title> <script type="text/javascript" src="../js/vue.js" ></script> <script> window.onload = () => { let vm = new Vue({ el : '.container', data : { imgUrl : '../res/images/', imgName : 'logo.png', goods : { id : '', name : '', price : '', num : '', type : '' }, goodsType : ['零食', '电子产品', '生活用品'], goodsArray : [ {id : '001', name : '可乐', price : 10, num : 10, type : '零食', addDate : '2019-02-23'}, {id : '002', name : '手机', price : 1000, num : 20, type : '电子产品', addDate : '2019-02-24'}, {id : '003', name : '毛巾', price : 5, num : 30, type : '生活用品', addDate : '2019-02-25'} ], colNum : 8 }, methods : { addGoods(){ this.goodsArray.push(this.goods); this.goods = {}; }, delGoods(index){ this.goodsArray.splice(index, 1); }, clearGoodsArray(){ this.goodsArray = []; } } }); } </script> <style type="text/css"> .container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; } .header{ margin: 10px; border: 1px solid gray; } .header .title{ color: rgb(53, 73, 93); background: rgb(65, 184, 131); } .logo{ position: relative; top: 12px; } .form-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .form-warp .content{ line-height: 35px; } .form-warp input{ width: 150px; height: 18px; } .form-warp select{ width: 154px; height: 24px; } .sub-title{ color: rgb(65, 184, 131); background: rgb(53, 73, 93); } .table-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .table-warp th{ width: 80px; color: #FFF; background-color: rgb(53, 73, 93); } .table-warp a{ text-decoration: none; } .clear-btn{ text-align: right; padding-right: 10px; } .fontColor{ color: gray; } .myBackgounrdColor{ background: rgb(65, 184, 131); } .myFontSize{ font-size: 200px; } </style> </head> <body> <div class="container"> <!--有logo和title--> <div class="header"> <img :src="imgUrl + imgName" class="logo" height="80px" /> <h1 class="title">Gary_商品管理</h1> </div> <!--输入部分input--> <div class="form-warp"></div> <div class = "title">添加商品</div> <div class="content"> 商品编号：<input type="text" placeholder="请输入商品编号" v-model="goods.id"/><br /> 商品名称：<input type="text" placeholder="请输入商品名称" v-model="goods.name"/><br /> 商品价格：<input type="text" placeholder="请输入商品价格" v-model="goods.price"/><br /> 商品数量：<input type="text" placeholder="请输入商品数量" v-model="goods.num"/><br /> 商品类型：<select v-model="goods.type"> <option value=""> -- 选择商品类型 --</option> <option v-for="type in goodsType">{{type}}</option> </select> </div> <div class="form-btn"></div> <button @click="addGoods">确认添加</button> <button @click="goods = {}">重置信息</button> <!--显示 表格--> <div class="table-wrap"> <h2 :class="{fontColor : goodsArray.length <= 0}" class="sub-title">商品列表</h2> <div class="content"> <table border="1" align="center" cellspacing="" cellpadding=""> <tr> <th>序号</th> <th>编号</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>类型</th> <th>删除</th> </tr> <tr> <td :colspan="colNum" height="150px" v-show="goodsArray.length <= 0">暂无商品</td> </tr> <tr v-for="(item, index) in goodsArray" :key="item.id"> <td>{{index}}</td> <td>{{item.id}}</td> <td>{{item.name}}</td> <td>{{item.price}}</td> <td>{{item.num}}</td> <td>{{item.type}}</td> <td> <button @click="delGoods(index)">删除</button> </td> </tr> </table> </div> <div> <a href="#" @click.prevent="clearGoodsArray" v-show="goodsArray.length > 0">清空全部</a> </div> </div> </div> </body> </html>
五、删除用户选中商品
使用input来存放选中商品的索引
在Vue数据域中添加delArray数据

为方便点击清空全部与删除选中索引，可以把清空全部按钮放置在右下角
添加选中商品链接
<div class="clear-btn"> <a href="#" @click.prevent="delSelected" v-show="delArray.length > 0">删除选中</a> <a href="#" @click.prevent="clearGoodsArray" v-show="goodsArray.length > 0">清空全部</a> </div>
delSelected(){ this.delArray.sort((a, b)=>{ return a - b; }); for(var i=0; i<this.delArray.length; i++){ this.goodsArray.splice(this.delArray[i] - i, 1); } this.delArray = []; } }
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Gary商品管理</title> <script type="text/javascript" src="../js/vue.js" ></script> <script> window.onload = () => { let vm = new Vue({ el : '.container', data : { imgUrl : '../res/images/', imgName : 'logo.png', goods : { id : '', name : '', price : '', num : '', type : '' }, goodsType : ['零食', '电子产品', '生活用品'], goodsArray : [ {id : '001', name : '可乐', price : 10, num : 10, type : '零食', addDate : '2019-02-23'}, {id : '002', name : '手机', price : 1000, num : 20, type : '电子产品', addDate : '2019-02-24'}, {id : '003', name : '毛巾', price : 5, num : 30, type : '生活用品', addDate : '2019-02-25'} ], colNum : 8, delArray:[] //删除选中的索引 }, methods : { addGoods(){ this.goodsArray.push(this.goods); this.goods = {}; }, delGoods(index){ this.goodsArray.splice(index, 1); }, clearGoodsArray(){ this.goodsArray = []; }, delSelected(){ this.delArray.sort((a, b)=>{ return a - b; }); for(var i=0; i<this.delArray.length; i++){ this.goodsArray.splice(this.delArray[i] - i, 1); } this.delArray = []; } } }); } </script> <style type="text/css"> .container{ margin: 0 auto; text-align: center; width: 1000px; border: 2px solid gray; } .header{ margin: 10px; border: 1px solid gray; } .header .title{ color: rgb(53, 73, 93); background: rgb(65, 184, 131); } .logo{ position: relative; top: 12px; } .form-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .form-warp .content{ line-height: 35px; } .form-warp input{ width: 150px; height: 18px; } .form-warp select{ width: 154px; height: 24px; } .sub-title{ color: rgb(65, 184, 131); background: rgb(53, 73, 93); } .table-warp{ margin: 10px; padding-bottom: 10px; border: 1px solid gray; } .table-warp th{ width: 80px; color: #FFF; background-color: rgb(53, 73, 93); } .table-warp a{ text-decoration: none; } .clear-btn{ text-align: right; padding-right: 10px; } .fontColor{ color: gray; } .myBackgounrdColor{ background: rgb(65, 184, 131); } .myFontSize{ font-size: 200px; } </style> </head> <body> <div class="container"> <!--有logo和title--> <div class="header"> <img :src="imgUrl + imgName" class="logo" height="80px" /> <h1 class="title">Gary_商品管理</h1> </div> <!--输入部分input--> <div class="form-warp"></div> <div class = "title">添加商品</div> <div class="content"> 商品编号：<input type="text" placeholder="请输入商品编号" v-model="goods.id"/><br /> 商品名称：<input type="text" placeholder="请输入商品名称" v-model="goods.name"/><br /> 商品价格：<input type="text" placeholder="请输入商品价格" v-model="goods.price"/><br /> 商品数量：<input type="text" placeholder="请输入商品数量" v-model="goods.num"/><br /> 商品类型：<select v-model="goods.type"> <option value=""> -- 选择商品类型 --</option> <option v-for="type in goodsType">{{type}}</option> </select> </div> <div class="form-btn"></div> <button @click="addGoods">确认添加</button> <button @click="goods = {}">重置信息</button> <!--显示 表格--> <div class="table-wrap"> <h2 :class="{fontColor : goodsArray.length <= 0}" class="sub-title">商品列表</h2> <div class="content"> <table border="1" align="center" cellspacing="" cellpadding=""> <tr> <th>序号</th> <th>编号</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>类型</th> <th>删除</th> <th>选择</th> </tr> <tr> <td :colspan="colNum" height="150px" v-show="goodsArray.length <= 0">暂无商品</td> </tr> <tr v-for="(item, index) in goodsArray" :key="item.id"> <td>{{index}}</td> <td>{{item.id}}</td> <td>{{item.name}}</td> <td>{{item.price}}</td> <td>{{item.num}}</td> <td>{{item.type}}</td> <td> <button @click="delGoods(index)">删除</button> </td> <td> <input type="checkbox" :value="index" v-model="delArray"/> </td> {{delArray}} </tr> </table> </div> <div class="clear-btn"> <a href="#" @click.prevent="delSelected" v-show="delArray.length > 0">删除选中</a> <a href="#" @click.prevent="clearGoodsArray" v-show="goodsArray.length > 0">清空全部</a> </div> </div> </div> </body> </html>
六、修改商品数量 增加入库信息属性
直接使用@click.prevent对商品数量的修改
<td style="display: flex;"> <a style="flex: 0.5;" href="#" @click.prevent="item.num = item.num-- <= 0 ? 0 : item.num--">-</a> {{item.num}} <a style="flex: 0.5;" href="#" @click.prevent="item.num++">+</a> </td>
添加商品日期字段
data : { imgUrl : '../res/images/', imgName : 'logo.png', goods : { id : '', name : '', price : '', num : '', type : '', addDate : '' }, goodsType : ['零食', '电子产品', '生活用品'], goodsArray : [ {id : '001', name : '可乐', price : 10, num : 10, type : '零食', addDate : '2019-02-23'}, {id : '002', name : '手机', price : 1000, num : 20, type : '电子产品', addDate : '2019-02-24'}, {id : '003', name : '毛巾', price : 5, num : 30, type : '生活用品', addDate : '2019-02-25'} ], colNum : 8, delArray:[] //删除选中的索引 }
将商品信息字段添加进表格当中
<th>入库日期</th> <td>{{item.addDate }}</td>
修改增加商品addGoods()函数
addGoods(){ var d = new Date(); var y = d.getFullYear(); var m = d.getMonth()+1; var day =d.getDate()<10?'0'+d.getDate() : d.getDate(); var myDate = y+ '-' + m +'-'+day; this.goods.addDate = myDate ; this.goodsArray.push(this.goods); this.goods = {}; }
