ThinkPHP+jQuery implements "load more"

In many web interfaces, demos that click buttons to load the latest pieces of data are used. The following example uses thinkphp+jquery Implementation example:

The result to be achieved is roughly as follows

First step

Template file

      <!--软件-->
      <p class="lists switcher-panel switcher-panel-cur">
        <ul class="xinhao">
          {volist name="apps" id="vo"}
          <li class="app-item link">
            <p class="list-img">
              <img src="/public/static/images/{$vo.Pic}" alt=""></p>
            <p class="list-cont">
              <p class="lt-c-tit">
                <h2>
                  <a href="#nogo" rel="external nofollow" rel="external nofollow" >{$vo.AppName}</a></h2>
                <span>8.59MB</span></p>
              <p class="lt-c-s-n">
                <p class="lt-c-s-n-l">
                  <p class="star">
                    <p style="width: 73%;"></p>
                  </p>
                </p>
                <span>{$vo.DownloadCount}万次下载</span></p>
            </p>
            <p class="btns">
              <a class="dl-btn js-downloadBtn" href="http://shouji.360tpcdn.com/170214/5aeae868026625e95b389b357fbdd186/com.ss.android.article.video_116.apk" rel="external nofollow" >
                <span></span>下载</a>
            </p>
          </li>
          {/volist}
        </ul>
        <if condition="count($apps) eq 5">
          <p 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>
          </p>
        </if>
        <p class="load-bar" id="tip">
        </p>
      </p>

The second step

Backend file

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！'));
  }

}

The third step

Template Asynchronous js in

  <script>
    //加载更多
    var nStart = 5;
    $(&#39;#loadmore&#39;).click(function() {
      var _this = $(".xinhao");
      if(nStart >= {$total}) {
        //alert(&#39;后面没有数据了！&#39;);
        $("#loadmore").text(&#39;没有数据了亲...&#39;).css({"border-top":"1px solid #d4d5d6","height":"30px","line-height":"30px"});
        return false;
      } else {
        $.post("{:url(&#39;Index/data&#39;)}", {start: nStart}, function(res) {
          $.each(res[&#39;result&#39;], function(i, item) {
            _this.append(&#39;<li class="app-item link">\
              <p class="list-img">\
              <img src="/public/static/images/&#39;+item.Pic+&#39;"alt=""/></p>\
              <p class="list-cont">\
              <p class="lt-c-tit">\
              <h2>\
              <a href="#nogo" rel="external nofollow" rel="external nofollow" >&#39;+item.AppName+&#39;</a></h2>\
            <span>8.59MB</span></p>\
            <p class="lt-c-s-n">\
              <p class="lt-c-s-n-l">\
              <p class="star">\
              <p style="width: 73%;"></p>\
              </p>\
              </p>\
              <span>&#39;+item.DownloadCount+&#39;万次下载</span></p>\
            </p>\
            <p class="btns">\
              <a class="dl-btn js-downloadBtn" href="#" rel="external nofollow" >\
              <span></span>下载</a>\
              </p>\
              </li>&#39;);
          });
        });
        nStart += 5;
      }
    });
    </script>
