5.使用方法
###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
);
$page = new Pager($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'",
);
$page = new Pager($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>
