vue父子组件的嵌套的示例代码
qq_24849765 人气:0本文介绍了vue父子组件的嵌套的示例代码,分享给大家,具体如下:
组件的注册:
先创建一个构造器
var myComponent = Vue.extend({ template: '...' })
用Vue.component注册,将构造器用作组件(例为全局组件)
Vue.component('my-component' , myComponent)
注册局部组件:
var Child = Vue.extend({ /* ... */ }) var Parent = Vue.extend({ template: '...', components: { // <my-component> 只能用在父组件模板内 'my-component': Child } })
注册语法糖,简化过程
// 在一个步骤中扩展与注册 Vue.component('my-component', { template: '<div>A custom component!</div>' }) // 局部注册也可以这么做 var Parent = Vue.extend({ components: { 'my-component': { template: '<div>A custom component!</div>' } } })
父子组件嵌套的例子:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>index</title> </head> <body> <div id="app"> <parent></parent> </div> <script src="vue.js"></script> <script> var childComponent = Vue.extend({ template: '<p>this is child template</p>' }); Vue.component("parent",{ template: '<p>this is parent template</p><child></child><child></child>', components: { 'child': childComponent, } }); var app = new Vue({ el: '#app' }); </script> </body> </html>
其与以下写法等价:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>index</title> </head> <body> <template id="child"> <p>this is child template</p> </template> <template id="parent"> <p>this is parent template</p> <child></child> <child></child> </template> <div id="app"> <parent></parent> </div> <script src="vue.js"></script> <script> var childComponent = Vue.extend({ template: '#child' }); Vue.component("parent",{ template: '#parent', components: { 'child': childComponent, } }); var app = new Vue({ el: '#app' }); </script> </body> </html>
