翻页功能对前端后端都是个难题啊！今天终于给踩了！哈哈！整理下方法，我是基于vueJs写的，同样适用于angular哈！
封装下载地址：vue.js翻页组件
效果截图：
整体实现逻辑，当用户点击页码时，ajax从后端获取数据，包括：records（当前页查询到的记录），totalRecords: 121（所有记录），currentPage（当前页码），totalPage（总页码），size（当前页显示数量），之后用我封装的算法assemblePageTurnerParams，算出页面展示哪些页码。
不得不说，我考虑的很全面的哈！！页码多的时候显示省略号，页码少的时候，则显示的少！
源码如下：
html
<!DOCTYPE html>
<html>
<head>
<title>vue翻页</title>
<link rel="stylesheet" type="text/css" href="css/pageTurner.css">
</head>
<body class="myApp">
<div class="wrapper">
<p class="records">当前展示 {{ pageTurner.records }} 条记录，共{{ pageTurner.totalRecords }} 条记录</p>
<ul class="page-turner-container clearfix">
<li v-on:click="queryData(pageTurner.currentPage-1)">«</li>
<!-- 首页 -->
<li v-on:click="queryData(1)" :class="pageTurner.currentPage == 1 ? 'current-page' : '' ">1</li>
<li v-if="pageTurner.currentPage>4 && pageTurner.totalPage>7" class="omit">...</li>
<!-- 展示页 -->
<li v-for="page in pageTurner.displayPageList" :class="page == pageTurner.currentPage ? 'current-page' : '' " v-on:click="queryData(page)">{{ page }}</li>
<!-- 尾页 -->
<li v-if="pageTurner.currentPage<pageTurner.totalPage-3 && pageTurner.totalPage>7 " class="omit" >...</li>
<li v-on:click="queryData(pageTurner.totalPage)" :class="pageTurner.currentPage == pageTurner.totalPage ? 'current-page' : '' " v-if="pageTurner.totalPage != 1 && pageTurner.totalPage>6">{{ pageTurner.totalPage }}</li>
<li v-on:click="queryData(pageTurner.currentPage+1)">»</li>
</ul>
</div>
<script type="text/javascript" src="lib/vue.js"></script>
<script type="text/javascript" src="pageTurner.js"></script>
</body>
</html>
