如何使用CodeMirror Lint中的lint突出显示语法错误并删除CodeMirror以使文本区正常

我有一个Nuxtjs/Vuejs应用程序，其中我有2textarea。一个用于XML，另一个用于JSON。我想突出显示XML/JSON中与特定行相对的语法错误，并向用户显示消息。如下所示：ErrorHighlighting Link

我尝试在我的Nuxtjs/Vuejs应用程序中实现它，但不能正常工作，并且我收到了一个基于JSHINT的错误，因为它没有导入。有人能告诉我如何在XML和JSON的CodeMirror处理的文本区域内的特定行上显示错误消息吗？

如果用户在我的应用程序中点击reset按钮，textarea变成正常的textarea而不是CodeError处理的区域，如果我想从我的textarea中删除CodeMirror美化。我尝试了answers from here，但似乎没有对我起作用。

我已经创建了CodeSandbox，请查看并提供您的建议：https://codesandbox.io/s/boring-water-g14zd?file=/pages/index.vue

解决方案

我终于找到了解决方案。

要删除CodeMirror，我们可以这样做：

      this.xmlEditor.toTextArea()
      this.xmlEditor = null

或进行一些验证，然后重置值：

      if (this.xmlEditor !== null) {
        document.getElementById('xml').value = ''
        this.xmlEditor.setValue('')
        this.xmlEditor.toTextArea()
        this.xmlEditor = null
      }

为了美化和显示语法错误，我使用了如下内容：

<template>
  <div>
    CODE MIRROR
    <div class="row">
      <div class="col-sm-3">
        <button class="btn btn-primary" @click="resetArea">
          Reset
        </button>
      </div>
    </div>
    <div class="row">
      <div class="col-md-1" />
      <div class="col-md-5">
        <div class="row">
          <div class="col-md-12" style="display: flex">
            <textarea
              id="xml"
              v-model="xmlInput"
              class="form-control"
              placeholder="XML Document"
              spellcheck="false"
              data-gramm="false"
              @input="convertToJSON()"
            />
          </div>
        </div>
      </div>
      <div class="col-md-5">
        <div class="row">
          <div class="col-md-12">
            <textarea
              id="json"
              v-model="jsonInput"
              class="form-control"
              placeholder="JSON Document"
              spellcheck="false"
              data-gramm="false"
              @input="convertToXML()"
            />
          </div>
        </div>
      </div>
      <div class="col-md-1" />
    </div>
  </div>
