要实现的效果是这样的:
每次点击显示更多按钮,都会往下显示2条数据,直到后面没有数据了。。
数据表:
articleList模板文件
<include file="./Application/Common/View/Public/header.html" />
<div class="container">
<volist name="list" id="vo">
<div class="panel panel-default">
<div class="panel-heading">{ $vo.title}</div>
<div class="panel-body">{ $vo.content}</div>
</div> </volist>
<if condition="count($list) eq 5">
<a class="btn btn-block btn-default" style="margin-bottom: 20px;" href="javascript:;">显示更多</a>
</if>
</div>
<script>
var nStart = 5;
$('.btn').click(function() {
var _this = $(this); if(nStart >= { $total}) {
alert('后面没有数据了!'); _this.text('后面没有数据了');
return false; } else {
$.post("{:U('articleAjax')}", {start: nStart},
function(res) { $.each(res['result'], function(i, item) { _this.before('<div class="panel panel-default">\ <div class="panel-heading">'+item.title+'</div>\ <div class="panel-body">'+item.content+'</div>\ </div>'); }); }); nStart += 2; } });
</script> <include file="./Application/Common/View/Public/footer.html" />
Index控制器中的articleList方法和articleAjax返回方法
// 文章列表 public function articleList() { $article = M('article'); $total = $article->count(); $this->assign('total', $total); $list = $article->limit(5)->order('id asc')->select(); $this->assign('list', $list); $this->display(); } // ajax异步加载文章 public function articleAjax() { $article = M('article'); $start = I('post.start'); $list = $article->limit($start, 2)->order('id asc')->select(); $this->ajaxReturn(array( 'result'=>$list,'status'=>1, 'msg'=>'获取成功!')); }
