element表单中一个elformitem下多个formitem项校验（循环校验）

在vue+element的项目中，需要对form表单下的一个form item中校验多项数据，如下图：

代码实现（需要注意prop的值）：

<div class="send-wrap">
        <div class="send-header">
            <p class="title">在线下单</p>
        </div>
        <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
            <div class="send-content">
                <div class="sign">
                    <svg class="zbIcon" aria-hidden="true">
                        <use xlink:href="#icon-jiaobiao"></use>
                    </svg>
                    <p>寄</p>
                </div>
                <div class="sendItem-form">
                    <div class="send-row">
                        <el-form-item  label="发货人" prop="name">
                            <el-input v-model="ruleForm.name" placeholder="请输入发货人"></el-input>
