1.封装element-plus table分页

<template><el-pagination:page-sizes="pageSizes"v-model:current-page="currentPage"v-model:page-size="pageSize":total="totals"@size-change="handleSizeChange"@current-change="handleCurrentChange":small="false":disabled="false":background="false"layout="total, sizes, prev, pager, next, jumper"/>
</template>

<script setup>
import { computed } from 'vue'const props = defineProps({totals: {required: true,type: Number,default: 0,},page: {type: Number,default: 1,},size: {type: Number,default: 20,},pageSizes: {type: Array,default() {return [ 10, 20, 30,40];},},
});
const emit = defineEmits(['update:page', 'update:size','pagination'])
const currentPage = computed({get: () => {return props.page},set: (val) => {emit('update:page', val)}
})
const pageSize = computed({get: () => {return props.size},set: (val) => {emit('update:page', 1)emit('update:size', val)}
})
function handleSizeChange(val) {if (currentPage.value * val > props.total) {currentPage.value = 1}emit('pagination', { page: currentPage.value, size: val })
}
function handleCurrentChange(val) {emit('pagination', { page: val, size: pageSize.value })
}
</script>
<style lang="scss" scoped>
</style>

2.全局注册

main.js

import Pagination from "@/components/element/Pagination.vue";

import App from './App.vue'
const app=createApp(App)

app.component('Pagination', Pagination)

3.页面使用

 <div class="page-panel"><Pagination:totals="totalElements":page="query.pageNum":size="query.pageSize"@pagination="handleQuery"/></div>

const handleQuery = (data) => {query.value.pageNum = data.page;query.value.pageSize = data.size;query();
};
