Vue2自定义封装Pagination分页组件
自定义传入:
当前页数(current),默认为1
每页条数(pageSize),默认为10
只有一页时是否隐藏分页(hideOnSinglePage),默认为false
数据总数(total),默认为0
显示的页码数组长度(pageListNum),默认为5
是否可以快速跳转至某页(showQuickJumper),默认为false
是否显示当前页数和数据总量(showTotal),默认为false
分页器展示位置,靠左left,居中center,靠右right(placement),默认为'right'
效果图如下:
鼠标悬浮时切换为箭头:
①创建自定义分页组件Pagination.vue:
共 {
{ totalPage }} 页 / {
{ total }} 条

②在要使用的页面引入分页器:
@change="changePage" :current="pagination.p" :pageSize="pagination.pageSize" :total="total" :hideOnSinglePage="hideOnSinglePage" :showQuickJumper="true" :showTotal="true" placement="right" v-if="pagination && total" /> import Pagination from '@/components/Pagination' components: { Pagination } hideOnSinglePage: false, total: 0, pagination: { pageSize: 10, p: 1 } changePage (pager) { // 分页器回调 this.$emit('change', pager) }
