基于Vuejs框架实现翻页组件

2018年05月11日  | 移动技术网IT编程  | 我要评论

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：

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>
