monaco-editor编辑器使用方法（vue3实现）

1、首先在vue3项目中安装monaco-editor

yarn add monaco-editor
yarn add  monaco-editor-webpack-plugin

2、封装编辑器组件：包括运行、复制、重置功能（运行功能下一篇更新）
主要是初始化编辑器，创建dom，配置相关参数。

<template>
  <div class="left-box">
    <div class="left-top">
      <div class="run">
        <div class="btn" v-if="codeType == 'HTML'" @click="runClick">运行</div>
      </div>
      <div class="title-center">
        <div class="title" @click="clickHtml('Vue')" :style="{ color: codeType == 'Vue' ? '#066fdb' : '#fbfbfb' }">Vue代码</div>
        <div class="title" style="margin: 0 10px">|</div>
        <div class="title" @click="clickHtml('HTML')" :style="{ color: codeType == 'HTML' ? '#066fdb' : '#fbfbfb' }">HTML代码</div>
      </div>
      <div class="copy">
        <div class="btn" @click="reset">重置</div>
        <div class="btn" @click="copy">复制</div>
      </div>
    </div>
    <div id="codeEditBox" class="codeEditBox"></div>
  </div>
</template>
