1、动态组件
# <component :is="who"></component>

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<button @click="who='home'">首页</button>
<button @click="who='good'">商品</button>
<button @click="who='order'">订单</button>
<hr>
<component :is="who"></component>
</div>
</body>
<script>
var home = {
template: `
<div>
<h1>首页</h1>
</div>
`
}
var good = {
template: `
<div>
<h1>商品页面</h1>
</div>
`
}
var order = {

`
}
var vm = new Vue({
el: '#app',
data: {
who: 'home'
},
components: {
home,
good,
order
}
})
</script>
</html>

3、保存输入的记录
<keep-alive>
<component :is="who"></component>
</keep-alive>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<button @click="who='home'">首页</button>
<button @click="who='good'">商品</button>
<button @click="who='order'">订单</button>
<hr>
<keep-alive>
<component :is="who"></component>
</keep-alive>
</div>
</body>
<script>
var home = {
template: `

`
}
var good = {
template: `
<div>
<h1>商品页面</h1>
<p>搜索商品：<input type="text" v-model="name">
<button @click="handleSearch">搜索</button>
</p>
</div>
`,
data() {
return {
name: ''
}
},
methods: {
handleSearch() {
alert(this.name)
}
}
}
var order = {
template: `
<div>
<h1>订单页面</h1>
</div>
`
}
var vm = new Vue({
el: '#app',
data: {

},
components: {
home,
