Question

我试图让Aframe和vuejs相互配合，但是控制台正在返回警告消息。我猜测这是因为在vue有机会更改属性值之前会检查属性值。

警告讯息

core:schema:warn Unknown property `color` for component/system `undefined`. +349ms 2aframe.js:327
core:schema:warn Unknown property `color` for component/system `undefined`. +2ms aframe.js:327
core:schema:warn Unknown property `color` for component/system `undefined`. +1ms aframe.js:327
core:schema:warn Unknown property `height` for component/system `undefined`. +1ms aframe.js:327
core:schema:warn Unknown property `color` for component/system `undefined`. +1s aframe.js:327

以下是代码：

App.vue

<template>
    <a-scene>
        <test-component v-for="block in blocks" :color="block.color" :position="block.pos"></test-component>
        <a-box :color="color" height="4"></a-box>
        <a-entity position="0 0 10" camera look-controls></a-entity>
    </a-scene>
</template>

<script>
import TestComponent from './TestComponent.vue';
require('aframe');

export default {
    name: 'app',
    components:{
        TestComponent,
    },
    data(){
        return {
            color: 'green',
            blocks: [
                {color: 'red', pos: "1 0 0"},
                {color: 'orange', pos: "2 0 0"},
                {color: 'yellow', pos: "3 0 0"}
            ]
        }
    },
    mounted(){
        //test to see if a-frame updates properly
        let that = this;
        setTimeout(function(){
            that.blocks.push({color: 'lime', pos: "4 0 0"})
        }, 1000)
        setTimeout(function(){
            that.blocks[3].pos = "5 0 0"
        }, 2000)
    }
}
</script>

TestComponent.vue

<template lang="html">
    <a-box :color="color" :position="position"></a-box>
</template>

<script>
export default {
    props: ['color','position'],
}
</script>

的index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>aframetest</title>
  </head>
  <body>
    <div id="app"></div>
    <script src="dist/build.js"></script>
  </body>
</html>

main.js

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

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

Answer 1

工作代码，设置更简单：
（vuejs 2.4.4 + aframe 0.6.1）

https://jsfiddle.net/jg6uhh21/

HTML：

<a-scene id="app">
  <test-component v-for="block in blocks" :color="block.color" :position="block.pos"></test-component>
  <a-entity position="0 0 10" camera look-controls></a-entity>
</a-scene>

的javascript：

Vue.component('test-component', {
  props: ['color','position'],
  template: `<a-box :color="color" :position="position"></a-box>`
})
new Vue({
  el: '#app',
  data(){
    return {
      blocks: [
        {color: 'red', pos: "1 0 0"},
        {color: 'orange', pos: "2 0 0"},
        {color: 'yellow', pos: "3 0 0"}
      ]
    }
  },
  mounted(){
    setTimeout(() => { 
      this.blocks.push({color: 'lime', pos: "4 0 0"})
    }, 1000)
    setTimeout(() =>{
      this.blocks[3].pos = "5 0 0"
    }, 2000)
  }
})

小型互动演示我以相同的方式组合了vue.js和aframe：

Answer 2

我一直在寻找相同问题的答案，所以我在GitHub上demo上进行游戏

我缺少的部分是

Vue.config.ignoredElements = [
  'a-scene',
  'a-entity',
  'a-camera',
  'a-box'
]

我对Vue有点陌生，我不知道Vue.config.ignoredElements存在。我将其添加到main.js中，并添加了我正在使用的所有aframe原语。

Aframe + vuejs - core：schema：warn组件/系统`undefined`的未知属性`color`。 + 10ms aframe.js：327
