vue父子组件的嵌套
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

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>
