注册全局组件
-
使用
Vue.component(...)
的方式创建全局组件,注册属性,创建模版 -
props
属性:父组件传递数据到子组件。高级内容:Prop属性、Prop验证等 -
this.$emit
:将事件传递给父级组件 -
<slot></slot>
:插槽
<div id="app">
<button-counter title="title1 : " @clicknow="clicknow">
<h2>hi...h2</h2>
</button-counter>
<hr/>
<button-counter title="title2 : "></button-counter>
</div>
<script>
// 全局注册
Vue.component('button-counter', {
props: ['title'], // 接收父组件传值
data: function () {
return {
count: 0
}
},
template: `<div><h1>hi...</h1>
<button v-on:click="clickfun">
{{title}} You clicked me {{ count }} times.</button>
<slot></slot>
</div>`,
methods:{
clickfun : function () {
this.count ++;
this.$emit('clicknow', this.count); // 给父组件传递事件
}
}
})
var vm = new Vue({
el : "#app",
data : {
},
methods:{
clicknow : function (e) {
console.log(e);
}
}
});
</script>
注册局部组件
按需引入组件:创建 Vue 实例时,使用 components
属性指定要使用的组件
<div id="app">
<test></test>
</div>
<script>
new Vue({
el: '#app',
components: {
'test': {
data: function() {
return {
title: 'local-scope-component'
}
},
template: '<h2> {{ title }} </h2>'
}
}
})
</script>
单文件组件
创建单文件组件
<template>
<div>
<h1> {{title}} </h1>
<h2> {{ msg }}</h2>
</div>
</template>
<script>
export default {
name: 'testComponent',
data: function() {
return {
title: ' test component '
}
},
props: {
msg: {
type: String,
default: ' [msg] '
}
}
}
</script>
<style>
</style>
局部引入:
<template>
<testComponent msg="mmmm"></testComponent>
</template>
<script>
import testComponent from './components/test.vue'
export default {
name: 'App',
components: {
testComponent
}
}
</script>
练手:封装 quill 富文本组件
npm i quill -S
version: ^1.3.7
- 封装组件
<template>
<div class="editors">
<div id="editor"></div>
</div>
</template>
<script>
import Quill from 'quill'
import 'quill/dist/quill.snow.css'
export default {
props: {
value: {
type: String
}
},
name: 'editorQuill',
data: function() {
return {
quill: undefined
}
},
mounted: function() {
this.initEditor()
},
methods: {
initEditor() {
this.quill = new Quill('#editor', {
theme: 'snow'
});
// 这样初始化不是一种好方法
this.quill.setContents([{
insert: this.value
}])
// this.$emit 有报错
this.quill.on('text-change', () => {
this.$emit('change', this.quill.getContents())
})
}
}
}
</script>
<style scoped>
.editors {
width: 450px;
}
</style>
- 引入并使用
<template>
<editor @change="changeEditor" v-bind:value="content">
</editor>
</template>
<script>
import editor from '@/components/outer/editor.vue'
export default {
name: 'App',
data: function() {
return {
content: 'engure'
}
},
components: {
editor
},
methods: {
changeEditor(tex) {
console.log(tex)
}
}
}
</script>
<style>
</style>
要点:封装组件的同时还需要考虑数据的出入
