我有这个模型npm uninstall -g composer-playground我有一个npm uninstall -g composer-playground npm install -g composer-playground npm ls -g --depth==0 |grep playground的属性，里面有一个数组files，在我的Vue组件中，我想逐个显示错误，而不是数组格式。

有什么办法吗？

errorMessages

Answer 1

您需要遍历errorMessages数组

<ul v-if="files.length">
  <li v-for="(file, index) in files" :key="file.id">
    <span>{{file.name}}</span> -
    <span v-if="file.error"> 
      <ol>
       <li v-for="err in file.response.errorMessages> {{ err }} </li>
      </ol>
    </span>
  </li>
</ul>

或者使用数组的.join方法（['hola', 'mundo'].join(", ") => 'hola, mundo'）

<span v-if="file.error">{{ file.response.errorMessages.join(", ") }}</span>
