之前一直接触都是原始的前端模型，jquery+bootstrap，冗杂的dom操作，繁琐的更新绑定。接触vue后，对前端MVVM框架有了全新的认识。本文是基于webpack+vue构建，由于之前的工作主要是基于java的服务端开发工作，对前端框架和组件的理解，不够深入，借此来记录在前端框架使用和构建中的点点滴滴。

此分页组件参照于bootstrap-datatable底部分页开发完成，相关参数增加自定义功能。

最终使用展现效果图如下，数据来源于cnodejs【https://cnodejs.org/】

底部分页组件主要由左侧当前数据项数量显示和右侧分页页码两部分组成。组件代码如下：

<template xmlns:v-on="http://www.w3.org/1999/xhtml" xmlns:v-bind="http://www.w3.org/1999/xhtml"> <div> <div> <div> <select v-on:change="menuChange()" v-model="limit"> <option v-for="item in menu" v-bind:value="item">{{item}}</option> </select> 记录/页，显示第 {{start}} 至 {{end}} 项记录，共 {{totalSize}} 项 </div> </div> <div> <ul> <li><a v-on:click="firstClick()" v-bind:class="{ 'disabled': cur == 1}">首页</a></li> <li><a v-on:click="preClick()" v-bind:class="{ 'disabled': cur == 1}">上一页</a></li> <li v-for="per in pages" v-bind:class="{ 'active': cur == per}"> <a v-on:click="pageClick(per)">{{ per }}</a> </li> <li><a v-on:click="nextClick()" v-bind:class="{ 'disabled': cur == totalPage}">下一页</a></li> <li><a v-on:click="lastClick()" v-bind:class="{ 'disabled': cur == totalPage}">尾页</a></li> <li><a>共<i>{{totalPage}}</i>页</a></li> </ul> </div> <div></div> </div> </template> <script> import Ajax from '../ajax' export default{ props: ['page-model'], data () { return { // 初始页 cur: 1, // 请求地址 url: this.pageModel.url ?

curPage : 1; curPage = curPage > totalPage ? totalPage : curPage; totalPage = curPage > totalPage ? curPage : totalPage; // 左侧页数 leftPage = curPage - Math.floor(pageNum / 2); leftPage = leftPage > 1 ? leftPage : 1; // 右侧页数 rightPage = curPage + Math.floor(pageNum / 2); rightPage = rightPage > totalPage ? totalPage : rightPage; var curPageNum = rightPage - leftPage + 1; // 左侧调整 if (curPageNum < pageNum && leftPage > 1) { leftPage = leftPage - (pageNum - curPageNum); leftPage = leftPage > 1 ? leftPage : 1; curPageNum = rightPage - leftPage + 1; } // 右侧调整 if (curPageNum < pageNum && rightPage < totalPage) { rightPage = rightPage + (pageNum - curPageNum); rightPage = rightPage > totalPage ? totalPage : rightPage; } var arr = []; for (var i = leftPage; i <= rightPage; i++) { arr.push(i); } return arr; } }, computed: { pages: function () { return this.getPage(this.cur, this.totalPage, this.perSize); } } } </script> <style> ul, li { margin: 0px; padding: 0px; } li { list-style: none; display: inline; } .page-bar li:first-child > a { margin-left: 0px } .page-bar a { border: 1px solid #ddd; text-decoration: none; position: relative; float: left; padding: 6px 12px; margin-left: -1px; line-height: 1.42857143; color: #337ab7; cursor: pointer; } .page-bar a:hover { background-color: #eee; } .page-bar .active a { color: #fff; cursor: default; background-color: #337ab7; border-color: #337ab7; } .page-bar i { font-style: normal; color: #d44950; margin: 0px 4px; font-size: 12px; } .page-bar .page-con, .page-size { width: 50%; display: block; height: 30px; float: left; line-height: 30px; } .page-bar .page-con ul { float: right; padding-left: 15px; padding-right: 15px; display: inline-block; padding-left: 0; } .page-bar .page-size div { padding-left: 15px; padding-right: 15px; font-size: 14px; } a.disabled { color: #777; background-color: #fff; border-color: #ddd; cursor: not-allowed; } a.disabled:hover { background-color: #fff; } .clear-both { clear: both; } select { border: solid 1px #ddd; appearance: none; -moz-appearance: none; -webkit-appearance: none; background: url("../assets/images/arrow.png") no-repeat scroll right center transparent; padding-right: 15px; padding-left: 15px; padding-top: 2px; padding-bottom: 2px; } select::-ms-expand { display: none; } </style>

组建模块使用，

<template> <Navbar></Navbar> <div> <table> <thead> <tr> <th>标题</th> <th width="20%">发布时间</th> <th width="10%">作者</th> <th width="10%">回复数</th> <th width="10%">访问数</th> </tr> </thead> <tbody> <tr v-show="!tabelEmpty" v-for="item in dataList"> <td>{{item.title}}</td> <td>{{item.create_at}}</td> <td>{{item.author.loginname}}</td> <td>{{item.reply_count}}</td> <td>{{item.visit_count}}</td> </tr> <tr v-show="tabelEmpty"> <td colspan="5">没有匹配的记录</td> </tr> </tbody> </table> </div> <Pagebar :page-model="pageModel"></Pagebar> </template> <script> import Navbar from '../components/navbar.vue' import Pagebar from '../components/table-pagebar.vue' export default {//这里是官方的写法，默认导出，ES6 components: { Navbar, Pagebar }, data () { return { allArticle: "", dataList: [], pageModel: { url: 'https://cnodejs.org/api/v1/topics', menu: [5, 10, 20] }, } }, computed: { tabelEmpty: function () { if (this.dataList) { return false; } else { return true; } } }, events: { refresh: function (e) { this.dataList = e; } } } </script> <style> body, table { font-size: 12px; } table { table-layout: fixed; empty-cells: show; border-collapse: collapse; width: 100%; margin: 10px 0; } td { height: 30px; } div.row { margin-left: 15px; margin-right: 15px; } h1, h2, h3 { font-size: 12px; margin: 0; padding: 0; } .table { border: 1px solid #ddd; background: #fff; } .table thead tr { background: #eee; } .table th { background-repeat: repeat-x; height: 30px; text-align: left; vertical-align: middle; } .table tr.empty { text-align: center; } .table td, .table th { border: 1px solid #ddd; padding: 0 1em 0; } .table tr:nth-child(odd) td { background-color: #f5f5f5; } </style>
