<!–总结–>
1、 v-on: => @
2、 v-bind:content => :content
3、 v-model 数据双向绑定
4、 全局组件 Vue.components("组件名（驼峰命名）", {})创建
5、 局部组件 var TodoItem = {}, 需要在父组件中用
components: {
TodoItem: TodoItem
}注册， 只有注册后才有效
6、 mvc模式主要在c, 面向dom, 主要是dom操作
7、 mvvm面向数据

8.父子组件传值
父–>子 通过v-bind:变量名来实现传值，子组件通过props属性接收父组件传的值
子–>父 通过this.$emit("事件名", "参数")向上一层触发事件，父组件通过@事件名来监听事件并接收子页面传递的参数

​9.splice（）：从数组中添加或者删除项目，然后返回被删除的项目

 

附录：

Vue内部提供全局组件方法:

<todo-item v-for="item in list"></todo-item>
Vue.component("命名", {
    template: "<li>todo Item</li>"
})

向子组件传递绑定内容：v-bind: content="item"

循环list时，将list每个值赋值给item

<todo-item v-for="item in list"></todo-item>

将item值通过v-bind传给<todo-item>，通过content变量传递

<todo-item v-bind="content"></todo-item>

子组件从父组件接收内容：props: [‘content’]

局部组件：

定义对象TodoItem：

var TodoItem = {
    props: [‘content’],
    template: "<li>{{content}}</li>"
}

将TodoItem组件注册到根Vue实例中：

components: {
    TodoItem: TodoItem
}
