vue.js学习之UI组件开发教程

作者:rayman_v

前端开发中,随着业务的增多,出于效率的考虑,我们对于组件化开发的需求也越来越迫切。下面这篇文章主要给大家介绍了关于vue.js之UI组件开发的相关资料,文中介绍的非常详细,需要的朋友们下面来一起看看吧。

本文主要给大家介绍了关于vue.js之UI组件开发的相关内容,分享出来供大家参考学习,下面来一起看看详细的介绍:

1. 新建组件:

<script src="/public/javascripts/vue.js"></script>
<style>
 #app1{background-color: red}
 #app2{background-color: blue}
</style>
<body>
<div id="app1">
 <box-one></box-one>
 <box-two></box-two>
 <boxThree></boxThree>
</div>
<div id="app2">
 <box-one></box-one>
 <box-two></box-two>
</div>
<box-one></box-one>
<box-two></box-two>
<script>
Vue.component('box-one', {
 template: '<div class="box-one">box-one</div>'
});
var app1 = new Vue({
 el: '#app1',
 components: {
 'box-two': {
  template: '<div class="box-two">box-two</div>'
 },
 'boxThree': {
  template: '<div class="boxThree">boxThree</div>'
 }
 }
});
var app2 = new Vue({
 el: '#app2'
});
</script>

2. 浏览器渲染网页标签的限制:

<script src="/public/javascripts/vue.js"></script>
<style>
 .red{background-color: red}
 .blue{background-color: blue}
</style>
<body>
<div id="app1">
 <table class="red">
 <box-one></box-one>
 </table>
 <select class="red">
 <box-two></box-two>
 </select>

 <table class="blue">
 <tr is="box-one"></tr>
 </table>
 <select class="blue">
 <option is="box-two"></option>
 </select>
</div>
<script>
Vue.component('box-one', {
 template: '<tr><td>box-one</td></tr>'
});
Vue.component('box-two', {
 template: '<option>option</option>'
});
var app1 = new Vue({
 el: '#app1'
});
</script>

3. 组件中的 data 数据集:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <done-button></done-button>
</div>
<script>
Vue.component('done-button', {
 template: '<button>{{text}}</button>',
 data: function (){
 return {
  text: 'ok'
 }
 }
});
var app1 = new Vue({
 el: '#app1'
});
</script>

4. 实例给组件传值:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <done-button text="submit" textOne="submit1" text-two="submit2"></done-button>
</div>
<script>
Vue.component('done-button', {
 template: '<button :data-text="text" :data-text-one="textOne" :data-text-two="textTwo">{{text}}</button>',
 props: ['text', 'textOne', 'textTwo']
});
var app1 = new Vue({
 el: '#app1'
});
</script>

5. 组件标签属性使用动态数据:

<script src="/public/javascripts/vue.js"></script>
<style>
 .appNumber{background-color: red}
</style>
<body>
<div id="app1">
 <done-button :number="appNumber"></done-button>
 <button class="appNumber" @click="appNumber++">{{appNumber}}</button>
</div>
<script>
Vue.component('done-button', {
 template: '<button @click="number++">{{number}}</button>',
 props: ['number']
});
new Vue({
 el: '#app1',
 data: {
 appNumber: 0
 }
});
</script>

6. 自定义组件属性的值的规则:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <done-button number1="a" number2="1" :number3="1" ></done-button>
</div>
<script>
Vue.component('done-button', {
 template: '<button :num1="number1" :num2="number2" :num3="number3">{{number1}}</button>',
 props: {
 number1: {
  type: Number
 },
 number2: {
  type: Number
 },
 number3: {
  type: Number
 }
 }
});
new Vue({
 el: '#app1'
});
</script>

{
 // 属性类型: String、Number、Boolean、Function、Object、Array,null-任意类型,
 // 可以使用数组多选
 type: null,

 // 是否必须被赋值:true、false
 required: false,

 // 默认值:可以是一般任意值或有返回值的函数
 default: '',

 // 自定义判断函数:参数 value 为调用时传入的值,
 // 返回 true、false 来通知 vue 机制是否报错
 validator: function(value){ return true } 
}

7. 组件内给实例发送通知:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <done-button v-on:child="father" ></done-button>
</div>
<script>
Vue.component('done-button', {
 template: '<button v-on:click="add()">增加</button>',
 methods: {
  add: function () {
   this.$emit('child', 11);
  }
 }
});
new Vue({
 el: '#app1',
 methods: {
  father: function(number) {
   console.log('father' + number);
  }
 }
});
</script>


8. 组件之间通信:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <done-button ></done-button>
 <cancel-button></cancel-button>
</div>
<script>
var bus = new Vue();
Vue.component('done-button', {
 template: '<button v-on:click="send()">发送</button>',
 methods: {
  send: function () {
   bus.$emit('done-emit', 11);
  }
 }
});
Vue.component('cancel-button', {
 template: '<p>{{text}}</p>',
 data: function (){
  return {
   text: '00'
  }
 },
 mounted: function() {
  var _this = this;
  bus.$on('done-emit', function(number) {
   _this.text = number;
  });
 }
});
new Vue({
 el: '#app1',
 methods: {
  call: function(value) {
   console.log('father:' + value);
  }
 }
});
</script>


9. 组件内容节点的分发:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <box></box>
 <box>
  <h4>box1</h4>
 </box>
 <box>{{box2Text}}</box>
</div>
<script>
Vue.component('box', {
 template: '<p><slot>默认</slot></p>'
});
new Vue({
 el: '#app1',
 data: {
  box2Text: 'box2'
 }
});
</script>

10. 多个 <slot> 标签之间的使用:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <box>
  <p>ppppp</p>

  <p slot="h4">h4</p>
  <h4 slot="h4">h4</h4>

  <p slot="h5">h5</p>
  <h5 slot="h5">h5</h5>
 </box>
</div>
</div>
<script>
Vue.component('box', {
 template: [
  '<div id="box">',
   '<div class="default">',
    '<slot></slot>',
   '</div>',
   '<div class="h4">',
    '<slot name="h4"></slot>',
   '</div>',
   '<div class="h5">',
    '<slot name="h5"></slot>',,
   '</div>',
  '</div>',
 ].join('')
});
new Vue({
 el: '#app1'
});
</script>

11. <slot> 标签回传数据给内容节点:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <box >
  <template scope="props">
   <span>{{props.text}}</span>
  </template>
 </box>
</div>
</div>
<script>
Vue.component('box', {
 template: '<div id="box"><slot v-for="i in items" :text="i"></slot></div>',
 data: function (){
  return {
   items: [0,1,2,3,4]
  }
 }
});
new Vue({
 el: '#app1'
});
</script>

12. 动态切换组件:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <component :is="view"></component>
 <button @click="view = 'inlinebox'">change</button>
</div>
</div>
<script>
Vue.component('box', {
 template: '<div id="box">box</div>',
});
Vue.component('inlinebox', {
 template: '<div id="inlinebox">inlinebox</div>'
});
new Vue({
 el: '#app1',
 data: {
  view: 'box'
 }
});
</script>


13. 在实例中访问子元素对象:

<script src="/public/javascripts/vue.js"></script>
<body>
<div id="app1">
 <box ref="box1"></box>
</div>
</div>
<script>
Vue.component('box', {
 template: '<div id="box">box</div>',
});
new Vue({
 el: '#app1',
 mounted: function() {
  console.log(this.$refs);
 }
});
</script>
