一、定义一个组件
定义一个组件: 1. 全局组件 var Aaa=Vue.extend({ template:‘<h3>我是标题3</h3>‘ }); Vue.component(‘aaa‘,Aaa); *组件里面放数据: data必须是函数的形式,函数必须返回一个对象(json) 2. 局部组件 放到某个组件内部 var vm=new Vue({ el:‘#box‘, data:{ bSign:true }, components:{ //局部组件 aaa:Aaa } });
1. 全局组件
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> <style> </style> </head> <body> <div id="box"> <aaa></aaa> </div> <script> var Aaa=Vue.extend({ template:‘<h3>我是标题3</h3>‘ }); Vue.component(‘aaa‘,Aaa); var vm=new Vue({ el:‘#box‘, data:{ bSign:true } }); </script> </body> </html>
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> <style> </style> </head> <body> <div id="box"> <my-aaa></my-aaa> </div> <script> //另外一种写法,全局 Vue.component(‘my-aaa‘,{ template:‘<strong>好</strong>‘ }); var vm=new Vue({ el:‘#box‘ }); </script> </body> </html>
组件里面放数据:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> </head> <body> <div id="box"> <aaa></aaa> </div> <script> var Aaa=Vue.extend({ //组件里面放数据:data必须是函数的形式,函数必须返回一个对象(json) data(){ return { msg:‘我是标题^^‘ }; }, methods:{ change(){ this.msg=‘changed‘ } }, template:‘<h3 @click="change">{{msg}}</h3>‘ }); Vue.component(‘aaa‘,Aaa);//放在这里是全局 var vm=new Vue({ el:‘#box‘, data:{ bSign:true } }); </script> </body> </html>
2. 局部组件
放到某个组件内部
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> <style> </style> </head> <body> <div id="box"> <aaa></aaa> <br/> <br/> <my-aaa></my-aaa> </div> <script> var Aaa=Vue.extend({ template:‘<h3>{{msg}}</h3>‘, data(){ return { msg:‘ddddd‘ } } }); var vm=new Vue({ el:‘#box‘, data:{ bSign:true }, components:{ //局部组件 aaa:Aaa, ‘my-aaa‘:Aaa//这里的my-aaa需要用引号 } }); </script> </body> </html>
另外一种写法,局部
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> <style> </style> </head> <body> <div id="box"> <my-aaa></my-aaa> </div> <script> var vm=new Vue({ el:‘#box‘, components:{ ‘my-aaa‘:{ data(){ return { msg:‘welcome vue‘ } }, methods:{ change(){ this.msg=‘changed‘; } }, template:‘<h2 @click="change">标题2->{{msg}}</h2>‘ } } }); </script> </body> </html>
二、配合模板
配合模板: 1. template:‘<h2 @click="change">标题2->{{msg}}</h2>‘ 2. 单独放到某个地方 a). <script type="x-template" id="aaa"> <h2 @click="change">标题2->{{msg}}</h2> </script> b). <template id="aaa"> <h1>标题1</h1> <ul> <li v-for="val in arr"> {{val}} </li> </ul> </template>
方法一:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> <style> </style> </head> <body> <div id="box"> <my-aaa></my-aaa> </div> <script type="x-template" id="aaa"> <h2 @click="change">标题2->{{msg}}</h2> <ul> <li>1111</li> <li>222</li> <li>3333</li> <li>1111</li> </ul> </script> <script> var vm=new Vue({ el:‘#box‘, components:{ ‘my-aaa‘:{ data(){ return { msg:‘welcome vue‘ } }, methods:{ change(){ this.msg=‘changed‘; } }, template:‘#aaa‘ } } }); </script> </body> </html>
方法二:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> <style> </style> </head> <body> <div id="box"> <my-aaa></my-aaa> </div> <template id="aaa"> <h1 @click="change">{{msg}}</h1> <ul> <li v-for="val in arr"> {{val}} </li> </ul> </template> <script> var vm=new Vue({ el:‘#box‘, components:{ ‘my-aaa‘:{ data(){ return { msg:‘welcome vue‘, arr:[‘apple‘,‘banana‘,‘orange‘] } }, methods:{ change(){ this.msg=‘changed title‘; } }, template:‘#aaa‘ } } }); </script> </body> </html>
三、动态组件
动态组件:
<component :is="组件名称"></component>
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="bower_components/vue/dist/vue.js"></script> <style> </style> </head> <body> <div id="box"> <input type="button" @click="a=‘aaa‘" value="aaa组件"> <input type="button" @click="a=‘bbb‘" value="bbb组件"> <component :is="a"></component> <!--<component :is="组件名称"></component>--> </div> <script> var vm=new Vue({ el:‘#box‘, data:{ a:‘aaa‘ }, components:{ ‘aaa‘:{ template:‘<h2>我是aaa组件</h2>‘ }, ‘bbb‘:{ template:‘<h2>我是bbb组件</h2>‘ } } }); </script> </body> </html>
