强大Vue.js组件浅析

var MyCompOnent= Vue.extend({
 // 选项...后面再介绍
}) 

// 定义
var MyCompOnent= Vue.extend({
 template: '
A custom component!
'
})

// 注册
Vue.component('my-component', MyComponent)

// 创建根实例
new Vue({
 el: '#example'
})

 

 
A custom component!

var child = Vue.extend({
 template: '
A custom component!
'
});
var parent = Vue.extend({

 template: '
Parent Component: 
',
 components: {
 'child-component': child
 }
});
Vue.component("parent-component", parent);

// 在一个步骤中扩展与注册
Vue.component('my-component', {
template: '
A custom component!
'
})

// 局部注册也可以这么做
var Parent = Vue.extend({
 components: {
 'my-component': {
  template: '
A custom component!
'
 }
 }
})

 Home
 Posts
 Archive
 

 

var vue = new Vue({
 el:"#dynamic",
 data: {
 currentView: "home"
 },
 components: {
 home:{
  template: "Home"
 },
 posts: {
  template: "Posts"
 },
 archive: {
  template: "Archive"
 }
 }
});
document.getElementById("home").Onclick= function(){
vue.currentView = "home";
};
document.getElementById("posts").Onclick= function(){
vue.currentView = "posts";
};
document.getElementById("archive").Onclick= function(){
vue.currentView = "archive";
};

var data = { a: 1 };
var vm = new Vue({
data: data
});
// `vm.a` 和 `data.a` 现在是响应的
vm.b = 2
// `vm.b` 不是响应的
data.b = 2
// `data.b` 不是响应的

var vm = new Vue({
 template: '
{{msg}}
'
})
// 然后添加 `msg`
vm.$set('msg', 'Hello!')

var vm = new Vue({
 data: {
 // 以一个空值声明 `msg`
 msg: ''
 },
 template: '
{{msg}}
'
})
// 然后设置 `msg`
vm.msg = 'Hello!'

 
 show modal
 
 
 
 
Custom Header
 

//定义一个插件，名称为modal
Vue.component("modal", {
 //插件的模板绑定id为modal-template的DOM元素内容
 template: "#modal-template",
 props: {
 //特性，类型为布尔
 show:{
  type: Boolean,
  required: true,
  twoWay: true
 }
 }
});
//实例化vue，作用域在id为app元素下，
new Vue({
 el: "#app",
 data: {
 //特性，默认值为false
 showModal: false
 }
});
