###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 $page->show(1); #2 ###处理ajax分页的情况#### method 处理环境 设置为 ajax# ajax_func_name ajax分页跳转页面的javascript方法# parameter ajax_func_name后面的附带参数 默认为空# now_page 不到当前页面所以只有你传入$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); #7#添加了parameter6
