由v-for生成的动态项目的元素UI验证

Question

我想使用element-ui和asyc-validator验证表中的字段,但没有得到任何线索我该怎么做!没有找到任何适当的文档和讨论主题,所以在这里发布我的问题.

vue模板:

<el-form :model='myForm' :rules='rules' ref='myForm'>
  <div v-for="(item, index) in items" :key="index">
    <div class="col">
      <el-form-item label="Description" prop="description">
        <el-input v-model="item.description"></el-input>    
      </el-form-item>
    <div>
    <div class="col">
      <el-form-item label="Price" prop="price">
        <el-input v-model="item.price"></el-input>    
      </el-form-item>
    <div>
  </div>
</el-form>

我试图像这样设置规则,但它不起作用

rules: {
  "description": { required: true, message: 'is required', trigger: 'blur' },
  "price": { required: true, message: 'is required', trigger: 'blur' }
}

这里是jsfiddle:https://jsfiddle.net/cgL6y9kq/15/ 尝试提交表单,即使您填写了必填字段,也会出现错误.

您需要使用索引动态设置:props,并在el-form-item中添加规则.在这里查看jsfiddle:https://jsfiddle.net/cgL6y9kq/34/

<el-form-item label="Description" 
  :prop="'items.' + index + '.description'"
  :rules="{required: true, message: 'description is required', trigger: 'blur'}">
    <el-input v-model="item.description"></el-input>
</el-form-item>
