Vue.js 加载单文件组件

Vue.js loading single-file components(Vue.js 加载单文件组件)

问题描述

我是 Vue.js 的新手，想使用单文件组件，但我不了解工作流程.

I'm new to Vue.js and want to use single-file components, but I don't understand the workflow.

比如我有三个组件:App、Grid和List

For example, I have three components: App, Grid and List

App.vue

<template>
    <div id="app">
        <div id="grid"></div>
        <div id="right"></div>
    </div>
</template>

<script>
    export default {
        name: 'app',
        data () {
            return {
                message: 'Hello Vue!'
            }
        }
    }
</script>

Grid.vue

<template>
    <div id="left"></div>
</template>

<script>
    export default {
        name: 'grid',
        data: function () {
            return {
                grid: 'some-data'
            }
        }
    }
</script>

List.vue

<template>
    <div id="right"></div>
</template>

<script>
    export default {
    name: 'list',
    data: function () {
        return {
            text: 'some-text'
        }
    }
}
</script>

Main.js

import Vue from 'vue'
import App from './vue/App.vue'
import Grid from './vue/Grid.vue'
import PatternList from './vue/PatternList.vue'

new Vue({
    el: '#app',
    render: h => h(App)
});

new Vue({
    el: '#grid',
    render: h => h(Grid)
});

new Vue({
    el: '#right',
    render: h => h(PatternList)
});

它有效，但我希望这不是创建嵌套组件的正确方法.

It works but I hope this isn't the right way to create nested components.

任何人都可以展示它应该做的方式吗?谢谢

Can anyone show the way it should be done? Thanks

推荐答案

您可以使用 Vue.component方法:

You can register components using the Vue.component method:

import Vue from 'vue'
import App from './vue/App.vue'
import Grid from './vue/Grid.vue'
import PatternList from './vue/PatternList.vue'

Vue.component('grid', Grid);
Vue.component('pattern-list', PatternList);

new Vue({
  el: '#app',
  render: h => h(App)
});

然后直接使用它们的标签名将它们添加到App模板中:

And then add them to the App template directly using their tag name:

<template>
  <div id="app">
    <grid></grid>
    <pattern-list></pattern-list>
  </div>
</template>

这会全局注册组件，这意味着任何 Vue 实例都可以将这些组件添加到他们的模板中，而无需任何额外的设置.

This registers the components globally, meaning that any Vue instance can add those components to their templates without any additional setup.

您还可以将组件注册到 Vue 实例，如下所示:

You can also register components to a Vue instance, like so:

new Vue({
  el: '#app',
  render: h => h(App),
  components: {
    'grid': Grid,
    'pattern-list': PatternList
  }
});

或者在单个文件组件的script标签内:

Or within the script tag of a single-file component:

<script>
import Grid from './vue/Grid.vue'

export default {
  name: 'app',
  components: {
    'grid': Grid,
    'pattern-list': PatternList
  }
});
</script>

这会将组件仅注册到该 Vue 实例，这意味着那些注册的组件将只能在该 Vue 实例的模板中使用.除非这些组件也注册到子 Vue 实例，否则子组件将无法访问那些已注册的组件.

This registers the components just to that Vue instance, meaning that those registered components will only be available to use within the template for that Vue instance. A child component would not have access to those registered components unless those components are also registered to the child Vue instance.
