在 Vue 中实现分页功能有几种常见方法,下面介绍几种主要的实现方式:
如果你使用 Element UI 组件库,可以很方便地使用其分页组件:
<template>
<div>
<!-- 表格数据展示 -->
<el-table :data="currentPageData" style="width: 100%">
<!-- 表格列定义 -->
</el-table>
<!-- 分页组件 -->
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page="currentPage"
:page-sizes="[10, 20, 30, 40]"
:page-size="pageSize"
layout="total, sizes, prev, pager, next, jumper"
:total="totalItems">
</el-pagination>
</div>
</template>
<script>
export default {
data() {
return {
allData: [], // 所有数据
currentPageData: [], // 当前页数据
currentPage: 1, // 当前页码
pageSize: 10, // 每页条数
totalItems: 0 // 总条数
}
},
created() {
this.fetchData();
},
methods: {
fetchData() {
// 模拟获取数据
// 实际项目中可能是 API 请求
this.allData = Array.from({length: 100}, (_, i) => ({ id: i + 1, name: `Item ${i + 1}` }));
this.totalItems = this.allData.length;
this.updateCurrentPageData();
},
updateCurrentPageData() {
const start = (this.currentPage - 1) * this.pageSize;
const end = start + this.pageSize;
this.currentPageData = this.allData.slice(start, end);
},
handleSizeChange(val) {
this.pageSize = val;
this.updateCurrentPageData();
},
handleCurrentChange(val) {
this.currentPage = val;
this.updateCurrentPageData();
}
}
}
</script>
如果不使用 UI 库,可以自己实现分页:
<template>
<div>
<ul>
<li v-for="item in currentPageData" :key="item.id">
{{ item.name }}
</li>
</ul>
<div class="pagination">
<button
@click="prevPage"
:disabled="currentPage === 1">
上一页
</button>
<span v-for="page in totalPages" :key="page">
<button
@click="goToPage(page)"
:class="{ active: currentPage === page }">
{{ page }}
</button>
</span>
<button
@click="nextPage"
:disabled="currentPage === totalPages">
下一页
</button>
</div>
</div>
</template>
<script>
export default {
data() {
return {
allData: [],
currentPageData: [],
currentPage: 1,
pageSize: 10
}
},
computed: {
totalPages() {
return Math.ceil(this.allData.length / this.pageSize);
}
},
created() {
this.fetchData();
},
methods: {
fetchData() {
// 模拟数据
this.allData = Array.from({length: 100}, (_, i) => ({ id: i + 1, name: `Item ${i + 1}` }));
this.updateCurrentPageData();
},
updateCurrentPageData() {
const start = (this.currentPage - 1) * this.pageSize;
const end = start + this.pageSize;
this.currentPageData = this.allData.slice(start, end);
},
prevPage() {
if (this.currentPage > 1) {
this.currentPage--;
this.updateCurrentPageData();
}
},
nextPage() {
if (this.currentPage < this.totalPages) {
this.currentPage++;
this.updateCurrentPageData();
}
},
goToPage(page) {
this.currentPage = page;
this.updateCurrentPageData();
}
}
}
</script>
<style>
.pagination button {
margin: 0 5px;
}
.pagination button.active {
font-weight: bold;
color: blue;
}
</style>
实际项目中,通常数据量较大,需要后端分页:
<template>
<div>
<el-table :data="tableData" style="width: 100%">
<!-- 表格列定义 -->
</el-table>
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page="currentPage"
:page-sizes="[10, 20, 30, 40]"
:page-size="pageSize"
layout="total, sizes, prev, pager, next, jumper"
:total="total">
</el-pagination>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
tableData: [],
currentPage: 1,
pageSize: 10,
total: 0
}
},
created() {
this.fetchData();
},
methods: {
async fetchData() {
try {
const response = await axios.get('/api/items', {
params: {
page: this.currentPage,
size: this.pageSize
}
});
this.tableData = response.data.items;
this.total = response.data.total;
} catch (error) {
console.error('获取数据失败:', error);
}
},
handleSizeChange(val) {
this.pageSize = val;
this.fetchData();
},
handleCurrentChange(val) {
this.currentPage = val;
this.fetchData();
}
}
}
</script>
对于大数据量,推荐使用后端分页,减少前端压力
分页组件通常需要显示总条数、每页条数选择、页码跳转等功能
可以添加加载状态,在数据请求时显示加载动画
考虑添加页码输入框,方便用户快速跳转到指定页
以上是 Vue 中实现分页的几种常见方法,你可以根据项目需求选择适合的方式。
