Vue.js 元素不会对react 性props 的更改做出react

我有这个代码的"显示代码"，它将呈现代码片段与不同的props 基于用户 Select 的语言上的代 docker (工作良好). image here个

<template>
    <div>
        <CodeHeader @language-selected="onLanguageSelected" />
        <CodeSnippet :language="selectedLanguage" :code="getCodeForLanguage(selectedLanguage)" />
        {{ selectedLanguage }} // WORKS
        {{ getCodeForLanguage(selectedLanguage)}} //WORKS

    </div>
</template>
            
<script>
import CodeSnippet from '@/components/atoms/CodeSnippet.vue';
import CodeHeader from '@/components/cells/CodeHeader.vue';

export default {
    name: 'ShowCode',
    components: {
        CodeSnippet,
        CodeHeader
    },
    data() {
        return {
            selectedLanguage: 'html', 
        };
    },
    methods: {
        onLanguageSelected(language) {
            language = language.toLowerCase();
            this.selectedLanguage = language;
        },
        getCodeForLanguage(language) {
            switch (language) {
                case 'html':
                    return '<h1>Oi</h1>';
                case 'css':
                    return '.h1 {}';
                case 'js':
                    return 'console.log(h1);';
                default:
                    return '';
            }
        },
    },
};
</script>

下面是我的代码片段:

<template>
    <div class="code-snippet">
      <pre>
        <vue-prism-component :code="code" :language="language"> {{ code }} {{ language }}</vue-prism-component>
      </pre>
    </div>
  </template>
  
  <script>
  import VuePrismComponent from 'vue-prism-component';
  import 'prismjs/themes/prism.css';
  
  export default {
    name: 'CodeSnippet',
    components: {
      VuePrismComponent
    },
    props: {
      code: {
        type: String,
            default: 
            `<h1>Oops! No code found.</h1>\n <p>Sad :(</p>`
            
      },
      language: {
        type: String,
            default: 'html'
      }
    }
  };
  </script>

在代码上，您可以看到这些工作:

{{seltedLanguage}}//Works {{getCodeForLanguage(SeltedLanguage)}}//Works

但代码片段不会更改.
