使用 vue element UI 框架对form内容 rules动态验证非空

<!-- 审核对话框 -->
    <el-dialog :title="dialogStatus" :visible.sync="dialogFormVisible">
      <el-form
        ref="dataForm"
        :rules="rules"
        :model="dataForm"
        status-icon
        label-position="left"
        label-width="100px"
        style="width: 400px; margin-left:50px;"
      >
        <el-form-item label="id" prop="id" hidden>
          <el-input v-model="dataForm.id" />
        </el-form-item>
        <el-form-item label="审核状态" prop="status" label-width="120px" >
          <el-radio v-model="dataForm.status" label="1" border @click="statusVisible = false">通过</el-radio>
          <el-radio v-model="dataForm.status" label="2" border @click="statusVisible = true">驳回</el-radio>

        <el-form-item label="佣金比例（%）" label-width="120px" prop="commission" :rules="dataForm.status!=2?rules.commission:[{ required: false, message: '请填写团长佣金比例（%）', trigger: 'blur' }]" >
          <el-input v-model="dataForm.commission" />
        </el-form-item>

    </el-dialog>

      rules: {
        status: [{ required: true, message: '请选择审核状态', trigger: 'blur' }],
        remarks: [{ required: false, message: '请填写驳回原因', trigger: 'blur' }],
        commission: [{ required: true, message: '请填写团长佣金比例（%）', trigger: 'blur' }]
      }

上述代码为核心实现区域；

下面是效果图；核心控制在于

        <el-form-item label="佣金比例（%）" label-width="120px" prop="commission" :rules="dataForm.status!=2?rules.commission:[{ required: false, message: '请填写团长佣金比例（%）', trigger: 'blur' }]" >
          <el-input v-model="dataForm.commission" />
        </el-form-item>
        <div :visible.sync="statusVisible">
          <el-form-item label="备注说明" label-width="120px" prop="remarks" :rules="dataForm.status!=2?rules.remarks:[{ required: true, message: '请填写驳回原因', trigger: 'blur' }]" >
            <el-input v-model="dataForm.remarks" type="textarea" />
          </el-form-item>
        </div>

      rules: {
        status: [{ required: true, message: '请选择审核状态', trigger: 'blur' }],
        remarks: [{ required: false, message: '请填写驳回原因', trigger: 'blur' }],
        commission: [{ required: true, message: '请填写团长佣金比例（%）', trigger: 'blur' }]
      }
