这个是基于vue2的分页封装，仿照elementUI而写的组件。
效果如图
话不多说，直接上代码
<template>
<div class="pagination">
<!-- 总页数 -->
<div class="total">共{{ total }}条</div>
<!-- 选择每页的条数 -->
<select name="" id="size_select" v-model="sizes" @change="sizeChange">
<option v-for="item in pageSizes" :key="item" :value="item">
{{ item }}条/页
</option>
</select>
<div class="pagenum">
<!-- 上一页 -->
<el-button
icon="el-icon-arrow-left"
:disabled="backDisabled"
circle
@click="back"
></el-button>
<!-- 页码 -->
<ul>
<li
:class="currentPage == item ? 'active' : ''"
v-for="(item, index) in pagenum"
:key="index"
@click="toPage(item)"
>
{{ item }}
</li>
</ul>
<!-- 下一页 -->
<el-button
icon="el-icon-arrow-right"
:disabled="forwardDisabled"
circle
@click="forward"
></el-button>
</div>
</div>
</template>
