Element中动态rules验证输入框的值 可以写很多条件的 rules数组

代码入下：

       <el-row :gutter="20" v-for="(receiverItem,receiverIndex) in form.receiverInfList" :key="receiverIndex">
          <el-col :span="8">
            <el-form-item 
            label="收货人" 
            :prop="'receiverInfList.' + receiverIndex + '.receiverName'"
            :rules="[{required:true,message:'收货人不能为空',trigger:'blur'}]"
            >
              <el-input v-model="receiverItem.receiverName" placeholder="请输入收货人" />
            </el-form-item>
          </el-col>
          <el-col :span="8">
            <el-form-item 
            label="收货人联系方式" 
            :prop="'receiverInfList.' + receiverIndex + '.receiverMblno'"
            :rules="[{required:true,message:'收货人联系方式不能为空',trigger:'blur'}]"
            >
              <el-input v-model="receiverItem.receiverMblno" placeholder="请输入收货人联系方式" />
            </el-form-item>
            
          </el-col>
          <el-col :span="1" v-if="isType !== 1">
            <i class="el-icon-delete deleteIcon" @click="onDeleteReceiver(receiverIndex)"></i>
          </el-col>
        </el-row>
