Ajax做列表无限加载和Ajax做二级下拉选项，供大家参考，具体内容如下：，//栏目Ajax做加载public function ajaxlist(){ //echo &quot；http：//www.域名.com/index.php？a=Index&c=Index&m=ajaxlist&quot；//echo &quot；&lt；hr&gt；&quot；$data = Q(&#39；sum&#39；)；$where = array()；$where[&#39；cid&#39；] = 33；$rongyuList = M(&#39；content&#39；)-&gt；limit($data，&quot；} echo &quot；]&quot；*/ }。
