###处理html静态化页面分页的情况#### method 处理环境 设置为 html # parameter 为静态页面参数  xxx.com/20-0-0-0-40-?.html 注意问号# ?问号的位置会自动替换为去向页码 # now_page 当前页面(静态页面获取不到当前页面所以只有你传入)$params = array(			'total_rows'=>100, #(必须)			'method'    =>'html', #(必须)			'parameter' =>'xxx.com/20-0-0-0-40-?.html',  #(必须)			'now_page'  =>$_GET['p'],  #(必须)			'list_rows' =>10, #(可选) 默认为15);$page = new Core_Lib_Page($params);   echo  $page->show(1);   #<a href="xxx.com/20-0-0-0-40-2.html">2</a>      ###处理ajax分页的情况#### method 处理环境 设置为 ajax# ajax_func_name ajax分页跳转页面的javascript方法# parameter    ajax_func_name后面的附带参数 默认为空# now_page 不到当前页面所以只有你传入$params = array(			'total_rows'=>100,			'method'    =>'ajax',			'ajax_func_name' =>'goToPage',			'now_page'  =>1,			#'parameter' =>"'jiong','username'",);$page = new Core_Lib_Page($params);   echo  $page->show(1);	    #<a href="javascript:void(0)" onclick="goToPage('7')">7</a>#添加了parameter<a href="javascript:void(0)" onclick="goToPage('6','jiong','username')">6</a>
