织梦dedecms首页列表页,ajax点击加载更多,瀑布流,首页多栏目切换-HTML建站博客

简化部分主要是栏目切换时,除子第一个默认栏目,其它的全改成ajax,不再生成静态页,而且通过PHP循环,简化了代码.另外加载更多按钮等也修改了触发形式.

一,模板

模板中涉及一个函数.get_url_by_typeid2() 在这里的说明

[html] view plain copy

二,,修改,plus/list.PHP 在require_once(dirname(__FILE__)."/../include/common.inc.php");

的下面增加一段

[php] view plain copy
