Hello world

  1. import: <script src=""></script>
  2. HTML ```html
3. javascript

var app = new Vue({
  el: '#app',
  data: {
    message: 'hello, world'


HTML 中用一个 mount point <div id="app">, 在 javascript 创建一个 Vue 示例。


  1. 文本插值: ``
  2. v-bind::title e.g. ` `
  3. v-on: @click 事件处理 ` `
  4. 条件: v-if
  5. 循环: v-for
  6. 用户输入: v-model: ` `


// 定义名为 todo-item 的新组件
Vue.component('todo-item', {
  template: '<li>这是个待办项</li>'

Instead, a component’s data option must be a function, so that each instance can maintain an independent copy of the returned data object:

data: function () {
  return {
    count: 0

Organizing components


Vue class / instance

var vm = new Vue({



  1. el: 锚点
  2. data: 要绑定的数据
  3. computed: 复杂属性
  4. props: 对外的属性接口,类似 C# /Android 中 view 等属性。
  5. methods: 方法


global config

Global API



synthetic events Creating and triggering events

vm.$emit( eventName, […args] )


  1. what is javascript prototype?


  2. what is javascript context this?

    The answer is short and simple: Scope pertains to the visibility of variables, and context refers to the object within which a function is executed.

javascript context/ scope/ this

context means this keyword

Context is most often determined by how a function is invoked. When a function is called as a method of an object, this is set to the object the method is called on:

So for a global function, this refers to ‘window’ in browser


new 3.x is @vue/cli, the old is vue-cli




➜  hello-vue git:(master) ✗ ./node_modules/.bin/vue-cli-service 

  Usage: vue-cli-service <command> [options]


    serve     start development server
    build     build for production
    inspect   inspect internal webpack config
    lint      lint and fix source files

  run vue-cli-service help [command] for usage of a specific command.



是一个 webpack 的 loader,可以将用下面这个格式编写的 Vue 组件转换为 JavaScript 模块:

AMD v.s. CommonJS v.s. UMD

Asynchronous Module Definition





vuex 集中管理应用中的状态。 类似 Java Spring 中的配置中心。 一种管理的哲学思想 commit 的方式相当于 会隐藏了 setOnListener 的调用, 类似 set 方法, 而不是直接访问状态字段

So actions/mutations allow you to:
