篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了一例基于thinkphp，jquery和bootstrap渲染的查询数据分页器相关的知识，希望对你有一定的参考价值。
对于某些查询记录很多的结果，web页面不得不采用分页器，现在奉上一例代码，其主要逻辑是：由页面的dom
节点发起ajax请求，返回的查询结果根据页面布局需要进行切片；并根据总记录数和页面展现的条数算出页码列表
html部分
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content=""> <meta name="author" content=""> <link rel="icon" href="../../../../favicon.ico"> <title>分页技术测试</title> <!-- Bootstrap core CSS --> <link href="/static/booststrap4/css/bootstrap.min.css" rel="stylesheet"> <!-- Custom styles for this template --> <link href="/static/mycss/starter-template.css" rel="stylesheet"> </head> <body> <nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top"> <a class="navbar-brand" href="#">Navbar</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarsExampleDefault"> <ul class="navbar-nav mr-auto"> <li class="nav-item active"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href="#" onclick="test()">Link</a> </li> <li class="nav-item"> <a class="nav-link disabled" href="#">Disabled</a> </li> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="http://example.com" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a> <div class="dropdown-menu" aria-labelledby="dropdown01"> <a class="dropdown-item" href="#">Action</a> <a class="dropdown-item" href="#">Another action</a> <a class="dropdown-item" href="#">Something else here</a> </div> </li> </ul> <form class="form-inline my-2 my-lg-0"> <input id="searchparam" class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search"> <button onclick = "startsearch()" class="btn btn-outline-success my-2 my-sm-0" type="button">Search</button> </form> </div> </nav> <main role="main" class="container"> <div class="starter-template"> <h1>Bootstrap starter template</h1> <div class="alert alert-primary" role="alert"> <table class="table"> <thead> <tr> </tr> </thead> <tbody> <tr> </tr> </tbody> </table> </div> <hr> <nav aria-label="Page navigation example"> <ul class="pagination"> <!-- <li id = "clickprev" class="page-item"><a onclick="moveprev()" class="page-link" href="#">Previous</a></li>--> <li id="pagememo"> <span style="margin-left:100px;"></span>共计：<span id="totalpage"></span>页<span style="margin-left:50px;"></span>当前第<span id="currentpage"></span>页 </li> </ul> </nav> </div> </main><!-- /.container --> <!-- Bootstrap core javascript ================================================== --> <!-- Placed at the end of the document so the pages load faster --> <script src="/static/booststrap4/js/jquery-3.3.1.min.js"></script> <script src="/static/myjs/forpage2.js"> </script> </body> </html>
thinkphp部分 use thinkmongoQuery; class Goodmaster extends Controller { function forpagination($tblname,$numperpage,$start,$end,$current) { $ret = Db::connect(‘db_mongo‘)->name($tblname)->select(); $resultlist=Array(); $totalnum = count($ret);//总记录数 $current=intval($current); $numperpage =intval($numperpage); //总页数=总记录数/每页面显示的条数 //关于页数分两种情况：1.总记录数大于每页显示的条数使用上述公式 //2.总记录数小于每页显示的条数，$totalpage = 1 if($totalnum<$numperpage) { $totalpage=1; $startpage = 1; $endpage = 1; $resultlist[‘ret‘] =$ret; } else{ $totalpage = ceil($totalnum/$numperpage); $startpage = $start; $endpage = $end; $leftindex =($current-1)*$numperpage;//数组切片左索引 $rightindex =$leftindex+$numperpage;//数组切片左索引 $subret = array_slice($ret,$leftindex,$numperpage); $resultlist[‘ret‘] =$subret; } $resultlist[‘totalpage‘] =$totalpage; $resultlist[‘frompage‘] =$startpage; $resultlist[‘current‘] =$current; $resultlist[‘topage‘] =$endpage; $resultlist[‘leftindex‘] =$leftindex; $resultlist[‘totalnum‘] =$totalnum; //return var_dump($resultlist); return $resultlist; } }
