我正在学习Vue.js并试图让嵌套组件渲染工作。
我开始使用以下(codepen here):
var buildingComponent = Vue.component('building', {
template: '#building-component',
name: 'building-component',
})
var roomComponent = Vue.component('room', {
template: '#room-component',
name: 'room-component',
props: ['number'],
})
var componentApp = new Vue({
el: "#components-example",
data: {
buildings: [
{id: 1, name: "144 Orange St", occupants: 5, rooms: [
{rid: 1, number: "122"},
{rid: 2, number: "123"},
{rid: 3, number: "144"},
]},
{id: 2, name: "92 Firth St", occupants: 6, rooms: [
{rid: 4, number: "155"},
{rid: 5, number: "344"},
{rid: 6, number: "343"},
]},
{id: 3, name: "123 Main St", occupants: 2, rooms: [
{rid: 7, number: "4324"},
{rid: 8, number: "1244"},
]},
],
},
})
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<!-- Components Example -->
<template id="building-component">
<div>
<span>Name: {{ bldg.name }}</span>
<ul v-if="bldg.rooms">
<room v-for="room in bldg.rooms" v-bind:room="room" number="room.number"></room>
</ul>
</div>
</template>
<template id="room-component">
<div>
<li>
<span>Room {{ room.number }}</span>
</li>
</div>
</template>
<p>Components example!</p>
<div id="components-example">
<ul>
<li v-for="bldg in buildings" v-bind:bldg="bldg"></li>
</ul>
</div>
我似乎无法让Vue.js正确呈现 - 我对{I} v-bind
以及在哪里感到有点困惑。
我当然喜欢所呈现的对基础实例数据属性的更改有100%反应。
知道我做错了吗?
答案 0 :(得分:1)
缺少一些东西:
template
属性。bldg
属性。number
属性,而不是room
