<script>
var vm = new Vue({

ctime: "",
list: [
{id: 1, name: "奔驰", ctime: new Date()},

var car = {id: this.id, name: this.name, ctime: new Date()}
this.list.push(car)
this.id = this.name = ""
}
}
})
</script>

2、删除品牌
<!doctype html>
<html lang="en">

<link rel="stylesheet" href="lib/bootstrap-3.3.7.css">
</head>
<body>
<div id="app">
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">添加品牌</h3>
</div>
<!--form-inline 让自己写的盒子在同一行显示-->
<div class="panel-body form-inline">
<label>
Id:
<input type="text" v-model="id">
</label>
<label>
Name:
<input type="text" v-model="name">
</label>
<!--在Vue中，添加事件绑定机制，如果给事件添加了小括号，那么就可以传参了-->
<input type="button" value="添加" class="btn btn-primary" v-on:click="add">
</div>
</div>
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th>Id</th>
<th>Name</th>
<th>Ctime</th>
<th>Operation</th>
</tr>
</thead>
<tbody>
<tr v-for="item in list" :key="item.id">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.ctime}}</td>
<td>
<a href="#" v-on:click.prevent="del(item.id)">删除</a>
</td>
</tr>
</tbody>
</table>
</div>
<script>
var vm = new Vue({
el: "#app",
data: {
id: "",
name: "",
ctime: "",
list: [
{id: 1, name: "奔驰", ctime: new Date()},
{id: 2, name: "众泰", ctime: new Date()},
{id: 3, name: "奥拓", ctime: new Date()},
]
},
methods: {
add() {
/*
获取到id和name，直接从data上面获取
组织出一个对象
把这个对象，调用数组的方法，添加到data上的list中
*/
var car = {id: this.id, name: this.name, ctime: new Date()}
this.list.push(car)
this.id = this.name = ""
},
del(id) {
/*
* 如何根据ID，找到要删除的信息的索引
*
* 如果找到索引了，直接调用数组的splice方法
* */
this.list.some((item, i) => {
if (item.id == id) {
// 在数组的some方法中，如果return true ，就会立即终止这个数组的后续循环
this.list.splice(i, 1)
return true
}
})
}
}
})
</script>
</body>
</html>
或者也可以写成这样
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>01品牌管理案例</title>
<script src="lib/vue-2.4.0.js"></script>
<link rel="stylesheet" href="lib/bootstrap-3.3.7.css">
</head>
<body>
<div id="app">
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">添加品牌</h3>
</div>
<!--form-inline 让自己写的盒子在同一行显示-->
<div class="panel-body form-inline">
<label>
Id:
<input type="text" v-model="id">
</label>
<label>
Name:
<input type="text" v-model="name">
</label>
<!--在Vue中，添加事件绑定机制，如果给事件添加了小括号，那么就可以传参了-->
<input type="button" value="添加" class="btn btn-primary" v-on:click="add">
</div>
</div>
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th>Id</th>
<th>Name</th>
<th>Ctime</th>
<th>Operation</th>
</tr>
</thead>
<tbody>
<tr v-for="item in list" :key="item.id">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.ctime}}</td>
<td>
<a href="#" v-on:click.prevent="del(item.id)">删除</a>
</td>
</tr>
</tbody>
</table>
</div>
<script>
var vm = new Vue({
el: "#app",
data: {
id: "",
name: "",
ctime: "",
list: [
{id: 1, name: "奔驰", ctime: new Date()},
{id: 2, name: "众泰", ctime: new Date()},
{id: 3, name: "奥拓", ctime: new Date()},
]
},
methods: {
add() {
/*
获取到id和name，直接从data上面获取
组织出一个对象
把这个对象，调用数组的方法，添加到data上的list中
*/
var car = {id: this.id, name: this.name, ctime: new Date()}
this.list.push(car)
this.id = this.name = ""
},
del(id) {
var index = this.list.findIndex(item => {
if (item.id == id) {
return true;
}
})
this.list.splice(index,1)
}
}
})
</script>
</body>
</html>
3、根据条件筛选品牌
<tbody>
<tr v-for="item in search(searchName)">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.ctime}}</td>
<td>
<a href="#" @click.prevent="del(item.id)">删除</a>
</td>
</tr>
</tbody>
search过滤方法中，使用 数组的filter方法进行过滤：
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>01品牌管理案例</title>
<script src="lib/vue-2.4.0.js"></script>
<link rel="stylesheet" href="lib/bootstrap-3.3.7.css">
</head>
<body>
<div id="app">
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">添加品牌</h3>
</div>
<!--form-inline 让自己写的盒子在同一行显示-->
<div class="panel-body form-inline">
<label>
Id:
<input type="text" v-model="id">
</label>
<label>
Name:
<input type="text" v-model="name">
</label>
<!--在Vue中，添加事件绑定机制，如果给事件添加了小括号，那么就可以传参了-->
<input type="button" value="添加" class="btn btn-primary" v-on:click="add">
<label>
搜索关键字：
<input type="text" class="form-control" v-model="keywords">
</label>
</div>
</div>
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th>Id</th>
<th>Name</th>
<th>Ctime</th>
<th>Operation</th>
</tr>
</thead>
<tbody>
<tr v-for="item in search(keywords)" :key="item.id">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.ctime}}</td>
<td>
<a href="#" v-on:click.prevent="del(item.id)">删除</a>
</td>
</tr>
</tbody>
</table>
</div>
<script>
var vm = new Vue({
el: "#app",
data: {
id: "",
name: "",
ctime: "",
keywords:"",
list: [
{id: 1, name: "奔驰", ctime: new Date()},
{id: 2, name: "众泰", ctime: new Date()},
{id: 3, name: "奥拓", ctime: new Date()},
]
},
methods: {
add() {
var car = {id: this.id, name: this.name, ctime: new Date()}
this.list.push(car)
this.id = this.name = ""
},
del(id) {
var index = this.list.findIndex(item => {
if (item.id == id) {
return true;
}
})
this.list.splice(index,1)
},
search(keywords){
var newList=this.list.filter(item=>{
if (item.name.includes(keywords)){
return item
}
})
return newList
}
}
})
</script>
</body>
</html>
