a-table绑定值变化,报错Cannot read properties of undefined reading '__asyncLoader'
- 1. 原代码
- 2. 更改后的代码
问题背景: vue3项目中使用ant-design-vue中的a-table,data-source绑定值为"tableData",页面加载时调用接口获得tableData显示正常,当输入筛选条件重新搜索后获得新的tableData,此时打印tableData值已经更新,但是页面没有变化,并报
Cannot read properties of undefined reading '__asyncLoader'
错误。
解决思路: 一开始以为值覆盖的问题,但是写死数据仍然报错,把template slot代码均注释掉,逐步排查找了两天没有找到问题,后面把a-table注释掉,改用list发现不报错,最终确定了是a-table中插槽的问题
解决方法: vue3中a-table不在使用
scopedSlots
插槽,改用v-slot:bodyCell
的形式使用插槽
1. 原代码
<a-table class="table" row-key="userId" :row-selection="{ selectedRowKeys: selectedRowKeys, onChange: onSelectChange }" :columns="tableHead" :data-source="tableData" :pagination="pagination" @change="handleTableChange"> <template slot="userName" slot-scope="userName,record"> <span style="color: #1890FF;cursor:pointer;" @click="handleDetails(record.userId)">{{ userName }}</span> </template> <template slot="dept" slot-scope="dept"> {{ dept ? dept.deptName : '' }} </template> <template slot="posts" slot-scope="posts"> <!-- {{ posts | showPosts }} --> {{posts[0].postName}} </template> <template slot="status" slot-scope="status, record"> <a-switch :checked="record.status === '0'" checked-children="启用" un-checked-children="禁用" @change="handleChange(status,record)" /> </template> <template slot="option" slot-scope="state, record"> <a-button type="link" @click="handleUpdate(record.userId)">编辑</a-button> <a-button type="link" @click="handleDelete(record.userId)">删除</a-button> <a-button type="link" @click="handleEquipment(record.userId)">设备权限</a-button> <a-button type="link" @click="resetPassword(record.userId)">重置密码</a-button> </template> </a-table>
