Vue
v-mode绑定在input中，关联data相关的数据
相当于input中的value，但是他能关联多个
<div id="app">
<input v-model="message1" >+
<input v-model="message2" >=
<input v-model="message3" >
<button id="a1" @click=aaa>点击相加</button>
</div>
主要用途：
数据的双向绑定（多向）
v-for
用于大部分数据重复，仅改变少部分数据
如：列表
事例：
<div class="a" v-for="item in items">我喜欢吃{{item.message}}<br></div>
new Vue({
el:"#app",
data:{
items:[
{message:"馒头"},
{message:"橘子"},
{message:"香蕉"},
{message:"苹果"},
{message:"梨子"}
]
}
})
1、new Vue({
el:"#app"
})
2、new Vue({}).$mount('#app');
创建组件的方式
公共组件
外部组件({}代表Vue.extend({}))
Vue.component('mycom1', {
template: '<div><input><a src="#a">我爱你</a></div>'
})
可以将标签放在body中，命名id
Vue.component('mycom1',{template: '#temp1'})
私有化组件
new Vue({
el: "#app",
components:{
'mycom1': {template: '<div><input><a src="#a">我爱你</a></div>'}
}
})
Vue回车键调用函数
<input type="text" value="button" @keyup.enter=kkk>
自调用函数
mounted(){
this.warning();
}

Vue路由创建
<html>
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<body>
<div id="app">
<h1>Hello App!</h1>
<p>
<!-- 使用 router-link 组件来导航. -->
<!-- 通过传入 `to` 属性指定链接. -->
<!-- <router-link> 默认会被渲染成一个 `<a>` 标签 -->
<router-link to="/foo">Go to Foo</router-link>
<router-link to="/bar122">Go to Bar</router-link>
</p>
<!-- 路由出口 -->
<!-- 路由匹配到的组件将渲染在这里 -->
<router-view></router-view>
</div>
<template id="temp1">
<h1>i love you</h1>
</template>
</body>
<script>
var router = new VueRouter({
routes:[
{ path: '/foo', component:{ template: '#temp1' } },
{ path: '/bar122', component: { template: '<div>bar</div>' } }
] // (缩写) 相当于 routes: routes
})
new Vue({
router
}).$mount('#app')
// 现在，应用已经启动了！
</script>
</html>
