分页功能
分页组件有两种
table组件自带分页
<Table
bordered
rowKey="userId"
rowSelection={{ type: 'checkbox' }}
pagination={{
position: ['bottomRight'],
pageSize: pagination.pageSize,
current: pagination.current,
showQuickJumper: true,
showSizeChanger: true,
onChange: (page, pageSize) => {
setPagination({
current: page,
pageSize
})
}
}}
dataSource={data}
/>
分页组件
<Pagination
pageNum={pagination.pageNum}
pageSize={pagination.pageSize}
total={pagination.total}
onChange={(pageNum: number, pageSize: number) => {
setPagination({
current: page,
pageSize
})
}}
/>
接口参数
{
pageNum: 1,
pageSize: 10,
userId: '',
userName: '',
state: ''
}
分页类型
export interface PageParams {
pageNum: number | undefined
pageSize?: number | undefined
}
用户列表参数类型
export interface Params extends PageParams {
userId?: number
userName?: string
state?: number
}
模拟列表数据
const list = Array.from({length:20})
.fill({})
.map((item:any)=>{
item = {...data.list[0]}
item.userId = Math.random()
return item
})
分页触发方式
- 进入页面，模拟初始化列表
- 点击搜索，初始化列表
- 点击页码，更新列表
- 点击每页条数， 更新列表
实现
