element-ui的el-table和el-form表单校验嵌套使用

在项目有遇到table中嵌套form,并且带有表单验证的需求,效果图如下:

 

 

 

刚开始el-form-item定义了静态prop(prop=“sn”),结果input填入值后错误提示一直存在,自定义校验的value也为undefined,然后经百度大神提点,得知出错在prop

  • ⚠️应该写动态prop保证唯一性。
:prop="'monitorData.' + scope.$index + '.sn'" 

 

  • ⚠️不只是el-form才配置,每一个el-form-item都要配置rules属性
  • <el-form :model="monitorForm" :rules="monitorForm.monitorRules" ref="monitorForm">
      <el-table
          class="blue-theme add-virtual-table"
          empty-text="请 新增填写行 进行填写"
          :data="monitorForm.monitorData"
          style="width: 100%;">
          <el-table-column
              type="index"
              align="center"
              width="50"/>
          <el-table-column
              prop="sn"
              label="SN">
              <template slot-scope="scope">
                <el-form-item 
                    :prop="'monitorData.' + scope.$index + '.sn'" 
                    :rules="monitorForm.monitorRules.sn">
                    <el-input
                        class="light-blue-theme"
                        clearable v-model="scope.row.sn"
                        placeholder="请输入sn"/>
                </el-form-item>
