ThinkPHP+jQuery实现“加载更多”

在很多web端界面中都会用到点击按钮加载最新几条数据的demo,下例为使用thinkphp+jquery实现实例：

要实现的结果大致如下

第一步

模板文件

 <!--软件-->
 <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>{$vo.DownloadCount}万次下载</span></div>
 </div>
 <div class="btns">
 <a class="dl-btn js-downloadBtn" href="http://shouji.360tpcdn.com/170214/5aeae868026625e95b389b357fbdd186/com.ss.android.article.video_116.apk" rel="external nofollow" >
 <span></span>下载</a>
 </div>
 </li>
 {/volist}
 </ul>
 <if condition="count($apps) eq 5">
 <div class="load-bar" id="loadmore">
 <a href="javascript:;" rel="external nofollow" class="user-pl-more-btn loadmore" data-type="1">加载更多</a>
 </div>
 </if>
 <div class="load-bar" id="tip">
 </div>
 </div>

第二步

后台文件

class Index
{
 //打印首页
 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'=>'获取成功！'));
 }

}

第三步

模板中的异步js

 <script>
 //加载更多
 var nStart = 5;
 $('#loadmore').click(function() {
 var _this = $(".xinhao");
 if(nStart >= {$total}) {
 //alert('后面没有数据了！');
 $("#loadmore").text('没有数据了亲...').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+'万次下载</span></div>\
 </div>\
 <div class="btns">\
 <a class="dl-btn js-downloadBtn" href="#" rel="external nofollow" >\
 <span></span>下载</a>\
 </div>\
 </li>');
 });
 });
 nStart += 5;
 }
 });
 </script>
