vue2.0 + ele的循环表单及验证字段方法

<el-form ref="ruleForm" :inline="true" :model="form" label-width="140px" :rules="rules"  v-loading.fullscreen.lock="fullScreenLoading" element-loading-text="拼命加载中...">  <div v-for="(item, index) in form.xh" @click="handleindex(index)">   <el-form-item label="账号" prop="tel">   <el-input v-model="item.tel" ></el-input>   </el-form-item>   <el-form-item label="姓名" prop="nickname" v-show="item.isnickname">   <el-input v-model="item.nickname"></el-input>   </el-form-item>  </div>  <el-form-item label="年龄" prop="age">   <el-input v-model="form.age"></el-input>  </el-form-item>  <el-form-item>   <el-button type="primary" @click="submitForm('ruleForm')">提交</el-button>   <el-button @click="onCancel">取消</el-button>  </el-form-item> </el-form>
