          </el-form-item>
        </el-row>

请问一下各位同志请问像这种情况要怎么进行表单校验,需要根据后台获取到的接口数据进行特定字段的表单校验,不同的数据校验的内容不同,我现在遇到的问题是我试过这样写

       <el-form-item
            v-if="editForm.data.category.properties"
            :key="item.id"
           :prop="`properties.` + index + `.value` "
            :label="item.property_name"
            :rules="item.required ?
              [{ required: true, message: '必填', trigger: ['blur','change'] }] : []
            "
            label-width="180px"
         / >

但是没有用,还是无法校验字段,比如说根据我的校验规则,按理来说应该是失去焦点或改变值就会触发校验的,但是校验并没有触发,感谢

要是数组对象这种就给按照这种去对应

<el-col :span="12" v-for="(item,index) in form.productParameters">
                                    <el-form :model="item" ref="formList" label-width="180px">
                                        <el-form-item :label="item.name" prop="paramValue"
                                            :rules="item.isKey=='true' ? [ { required: true, message: item.name+'不能为空', trigger: ['blur','change'] }] :[]">
                                            <el-input v-model="item.paramValue" style="width:100%">
                                            </el-input>
                                        
                                        </el-form-item>
                                    </el-form>
                                </el-col>

```
