ThinkPHP+jQuery實現“加載更多”
在很多web端界面中都會用到點擊按鈕加載最新幾條數據的demo,下例為使用thinkphp+jquery實現實例：
要實現的結果大致如下
第一步
模板文件
<!--軟件--> <div class="lists switcher-panel switcher-panel-cur"> <ul class="xinhao"> {volist name="apps" id="vo"} <li class="app-item link"> <div class="list-img"> <img src="/public/static/images/{$vo.Pic}" alt=""></div> <div class="list-cont"> <div class="lt-c-tit"> <h2> <a href="#nogo" rel="external nofollow" rel="external nofollow" >{$vo.AppName}</a></h2> <span>8.59MB</span></div> <div class="lt-c-s-n"> <div class="lt-c-s-n-l"> <div class="star"> <p style="width: 73%;"></p> </div> </div> <span>{$vo.DownloadCount}萬次下載</span></div> </div> <div class="btns"> <a class="dl-btn js-downloadBtn" rel="external nofollow" > <span></span>下載</a> </div> </li> {/volist} </ul> <if condition="count($apps) eq 5"> <div class="load-bar" id="loadmore"> <a href="javascript:;" rel="external nofollow" class="user-pl-more-btn loadmore" data-type="1">加載更多</a> </div> </if> <div class="load-bar" id="tip"> </div> </div>第二步
后臺文件
class Index{ //打印首頁 public function index() { $total=db('apps')->count(); $apps=db('apps')->where('AppStatus',1)->limit(5)->order("AppID ASC")->select(); //var_dump($apps); $view = new View(); $view->assign('total',$total); $view->assign('apps',$apps); return $view->fetch('index'); } public function data() { $start = Input('post.start'); //echo($start); $list = db('apps')->limit($start, 5)->order('AppID asc')->select(); return (array( 'result'=>$list,'status'=>1, 'msg'=>'獲取成功！')); }}第三步
模板中的異步js
<script> //加載更多 var nStart = 5; $('#loadmore').click(function() { var _this = $(".xinhao"); if(nStart >= {$total}) { //alert('后面沒有數據了！'); $("#loadmore").text('沒有數據了親...').css({"border-top":"1px solid #d4d5d6","height":"30px","line-height":"30px"}); return false; } else { $.post("{:url('Index/data')}", {start: nStart}, function(res) { $.each(res['result'], function(i, item) { _this.append('<li class="app-item link">/ <div class="list-img">/ <img src="/public/static/images/'+item.Pic+'"alt=""/></div>/ <div class="list-cont">/ <div class="lt-c-tit">/ <h2>/ <a href="#nogo" rel="external nofollow" rel="external nofollow" >'+item.AppName+'</a></h2>/ <span>8.59MB</span></div>/ <div class="lt-c-s-n">/ <div class="lt-c-s-n-l">/ <div class="star">/ <p style="width: 73%;"></p>/ </div>/ </div>/ <span>'+item.DownloadCount+'萬次下載</span></div>/ </div>/ <div class="btns">/ <a class="dl-btn js-downloadBtn" href="#" rel="external nofollow" >/ <span></span>下載</a>/ </div>/ </li>'); }); }); nStart += 5; } }); </script>以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
