test2.php : 

<?php          print_r(@$_post['list']);  ?>

try this:
1:you use <input></input> wrong!!! <input type='checkbox' name='' />
2:you each checkbox can each $('input.cb:checked') , remove if
3:you want post ajax use $.post

<html> <head> <script src="http://code.jquery.com/jquery-1.9.1.js" type="text/javascript" charset="utf-8"></script>   <script type="text/javascript">                 function doit() {                         var p=[];                         $('input.cb:checked').each(function(index,value) {                                                                         p.push($(value).attr('rel'));                         });                         $.post('/test2.php',{list:p}).done(function(res) {alert(res);});                 }         </script> </head> <body>                <input type="checkbox" class="cb" rel="1"/>this 1<br />         <input type="checkbox" class="cb" rel="abc"/>this abc<br />         <input type="checkbox" class="cb" rel="999"/>this 999<br />         <a href="javascript:void(0)" onclick="doit()">click</a>        </body> </html>
