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:

基于Vuejs框架实现翻页组件

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 ">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 " 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 " 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="/UploadFiles/2021-04-02/vue.js">

P70系列延期,华为新旗舰将在下月发布

3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。

而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?

根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
