属性
首先我们先要了解分页器的属性
v-model:current-page当前页码
v-model:page-size设置每页展示数据的条数
page-sizes每页显示个数选择器的个数
small是否使用小型分页样式
disabled 是否禁用分页
background 是否为分页按钮添加背景色
total 总条目数
layout 组件布局,子组件名用逗号分隔
size-change下拉菜单发生变化的时候
current-change当前页面发生改变事件
需求
需求:当每页显示条数发生变化时,页数(数据足够)可能还在当前页,或者最后一页(数据不够)
需求:当每页显示条数发生变化时,页数回归第一页文章来源:https://www.toymoban.com/news/detail-742298.html

页面代码
<script setup lang="ts">
import { onMounted, ref } from 'vue'
import { reqAllUser } from '@/api/user/index'
import type { allUser, allUserReponseData } from '@/api/user/type'
const userData = ref<allUser[]>([])
//分页器当前页码
const page = ref<number>(1)
//每一页展示几条数据
const pageSize = ref<number>(10)
const total = ref<number>(0)
//处理分页模块
const handleSizeChange = () => {
getAllUser()
}
//处理分页模块结束
//获取所有用户模块
const getAllUser = async (pager = 1) => {
page.value = pager
const res: allUserReponseData = await reqAllUser(page.value, pageSize.value)
console.log(res, '111')
if (res.code == 200) {
total.value = res.total
userData.value = res.data
}
}
onMounted(() => {
//获取所有用户模块
getAllUser()
})
