红粒炊畲粟,青烟郁涧薪。得床思熟睡,寒犬苦狺狺。一生之中至少要有两次冲动,一次为奋不顾身的爱情,一次为说走就走的旅行。
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/{$vo.Pic}" alt=""></div> <div class="list-cont"> <div class="lt-c-tit"> <h2> <a rel="nofollow noopener noreferrer" href="#nogo" rel="external nofollow" rel="external nofollow" >{$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>{$vo.DownloadCount}万次下载</span></div> </div> <div class="btns"> <a class="dl-btn js-downloadBtn" rel="nofollow noopener noreferrer" href="http://shouji.360tpcdn.com/170214/5aeae868026625e95b389b357fbdd186/com.ss.android.article.video_116.apk" rel="external nofollow" > <span></span>下载</a> </div> </li> {/volist} </ul> <if condition="count($apps) eq 5"> <div class="load-bar" id="loadmore"> <a rel="nofollow noopener noreferrer" 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 rel="nofollow noopener noreferrer" 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" rel="nofollow noopener noreferrer" href="#" rel="external nofollow" >\ <span></span>下载</a>\ </div>\ </li>'); }); }); nStart += 5; } }); </script>
以上就是ThinkPHP+jquery实现“加载更多”功能代码。我能在冬天的严酷环境中生存下来,可能我会在春天是最漂亮的。更多关于ThinkPHP+jquery实现“加载更多”功能代码请关注haodaima.com其它相关文章!
