thinkphp增加每页显示条数的方法

需求是多加一个类似phpmyadmin一样的每页显示条数，在网上查了好久都没找到，看到thinkphp分页类是html拼接的，很low，但是方便了我修改没，就在原生分页类基础上新定义了一个num变量，show方法返回的时候 thinkphp拼接html的地方，新加了一段选择条数的代码，如下：

return"<ulclass='am-paginationam-pagination-right'>{$page_str}</ul><divclass='am-dropdownam-dropdown-up'data-am-dropdown><buttonclass='am-btnam-btn-primaryam-dropdown-toggle'data-am-dropdown-toggle>显示条数<spanclass='am-icon-caret-up'></span></button><ulclass='am-dropdown-content'><li><ahref='".$this->urlNum(10,1)."'>10</a></li><li><ahref='".$this->urlNum(30,1)."'>30</a></li><li><ahref='".$this->urlNum(50,1)."'>50</a></li></ul></div>";

然后新加的urlNum方法是这样：

privatefunctionurlNum($num,$page){$str=str_replace(urlencode('[PAGE]'),$page,$this->url);returnstr_replace(urlencode('[NUM]'),$num,$str);}

开始的时候由于page这个变量 thinkphp会先变一个转码的，后面才替换；而且page=1的时候 url里是不显示的，但是还有这个参数，导致num这个变量老是搞得url 很不稳定、经常叠加。

后面只有做了一个小牺牲(选定每页显示条数的时候 url page即使为1 也会加上)，不过这并没有什么影响。

整个代码分页类 就是这样：

效果如下：
