      手把手教你實(shí)現(xiàn)thinkphp ajax無(wú)刷新分頁(yè)

      下面thinkphp框架教程欄目將給大家介紹怎么實(shí)現(xiàn)thinkphp的ajax無(wú)刷新分頁(yè),希望對(duì)需要的朋友有所幫助!

      前言

      thinkphp框架自帶的分頁(yè)類是每次翻頁(yè)都要刷新一下整個(gè)頁(yè)面,這種翻頁(yè)的用戶體驗(yàn)顯然是不太理想的,我們希望每次翻頁(yè)只刷新我們想要的數(shù)據(jù)集部分的數(shù)據(jù),這樣我們很容易想到ajax異步通信,用ajax與數(shù)據(jù)庫(kù)(本人在開(kāi)發(fā)過(guò)程中使用的是mysql數(shù)據(jù)庫(kù))異步交互,將從數(shù)據(jù)庫(kù)查詢的數(shù)據(jù)返回,用jquery替換原有的數(shù)據(jù),從而在不刷新這個(gè)頁(yè)面的情況下進(jìn)行局部刷新,從而達(dá)到我們預(yù)期的效果。

      thinkphp ajax 分頁(yè)類

      這個(gè)分頁(yè)類是網(wǎng)上找到的資源,大家可以直接在自己的thinkphp里創(chuàng)建這么一個(gè)類,我這里類名是 AjaxPage.class.php

      具體步驟

      接下來(lái),我們從控制器開(kāi)始一步一步地實(shí)現(xiàn)thinkphp無(wú)刷新分頁(yè)這個(gè)效果。

      1.控制器部分

      這只是控制器的一部分比較核心的代碼。

              //實(shí)例化數(shù)據(jù)模型         $info=M('info');         //統(tǒng)計(jì)要查詢數(shù)據(jù)的數(shù)量         $count=$info->where("ID='$id'")->count();         //實(shí)例化分頁(yè)類,傳入三個(gè)參數(shù),分別是數(shù)據(jù)總數(shù)、每頁(yè)顯示的數(shù)據(jù)條數(shù)、要調(diào)用的jQuery ajax方法名         $p=new HostCommonAjaxPage($count,10,'server');         //產(chǎn)生分頁(yè)信息         $page=$p->show();         //要查詢的數(shù)據(jù),limit表示每頁(yè)查詢的數(shù)量,這里為10條         $data = $server_info->where("ID='$id'")->limit($p->firstRow.','.$p->listRows)->select();         //assign方法往模板賦值         $this->assign('list',$data);         $this->assign('page',$page);         //ajax返回信息         $res["content"] = $this->fetch('Index/myinfolist')         $this->ajaxReturn($res);

      2.模板部分

      模板名:myinfolist.html與上面控制器中渲染的模板一致。

       $res["content"] = $this->fetch('Index/myinfolist')

      因?yàn)榍岸擞玫腷ootstrap框架,所以這個(gè)模板里的好多class是bootstrap里的,大家也不必過(guò)分糾結(jié)這個(gè),看整個(gè)過(guò)程的重點(diǎn)就好。

      <!DOCTYPE html> <head> </head>     <p id="server">         <p class="row-fluid"  >             <p class="span12">                 <p class="portlet box green">                     <p class="portlet-title">                         <p class="caption"><i class="icon-globe"></i>信息列表</p>                     </p>                      <p class="portlet-body" >                                          <table class="table table-striped table-bordered table-hover table-full-width" id="sample_1">                              <thead>                                  <tr>                                     <th class="hidden-480">a</th>                                     <th class="hidden-480">b</th>                                     <th class="hidden-480">c</th>                                     <th class="hidden-480">d</th>                                 </tr>                              </thead>                              <tbody>                                     //循環(huán)賦值                                     <foreach name='list' item='info'>                                         <tr>                                             <td>{$info.a}</td>                                             <td>{$info.b}</td>                                                  <td>{$info.c}</td>                                             <td>{$info.d}</td>                                                                                   </tr>                                     </foreach>                                                              </tbody>                                                      </table>                         //分頁(yè)信息                         <p class="row-fluid"> {$page} </p>                                              </p>                 </p>                 </p>                 </p>     </p>          <script src="__PUBLIC__/server.js"></script>  </html>

      3.js部分

      這一步是實(shí)現(xiàn)ajax無(wú)刷新分頁(yè)的重點(diǎn),用到了jQuery的ajax通信,通過(guò)與數(shù)據(jù)庫(kù)的ajax交互,將獲取到的數(shù)據(jù)寫到模板中,替換掉之前的數(shù)據(jù)集,達(dá)到分頁(yè)的目的。
      server.js

      function server(id){            var id = id;             $.get('/Server/myinfo', {'p':id}, function(data){               //用get方法發(fā)送信息到Server中的myinfo方法              $("#server").replaceWith("<p  id='user7'>"              +data.content+              "</p>");          });     }

      這個(gè)方法名 server 就是控制器中實(shí)例化分頁(yè)類中傳的第三個(gè)參數(shù),每次在模板上點(diǎn)擊翻頁(yè),都會(huì)觸發(fā)這個(gè)js方法server(p),里面?zhèn)鬟f的是第幾頁(yè)的頁(yè)碼。

      $p=new HostCommonAjaxPage($count,10,'server');

      這里用到的是jQuery里ajax方法的.get形式進(jìn)行ajax與后臺(tái)通信,拿到返回的數(shù)據(jù)用replaceWith方法,用

      <p  id='user7'>+數(shù)據(jù)</p>

      替換模板中id為server的p,實(shí)現(xiàn)分頁(yè)效果。

      小結(jié)

      上面的步驟就是實(shí)現(xiàn)ajax分頁(yè)的具體步驟,jQuery的ajax方法有$.ajax 、$.get 、 $.post三種,這里就不做介紹,代碼粘自我的程序中,為了不公開(kāi)我的一些數(shù)據(jù)字段,就用abcd代替了,也做了一定的刪減,有問(wèn)題希望大家指正,多多交流。
