ajax+php处理案例

 <div>
     <table>
         <tr>
             <th>状态</th>
             <th>信息</th>
         </tr>
         <tr>
             <td>00</td>
             <td>显示信息</td>
         </tr>
     </table>
 </div>
   <input type="submit" name="xx" value="提交">

js部分:

 <script src="jquery.js"></script>
 <script>
 $(function(){
     $('input[name="xx"]').click(function(){
         //alert('123');
         $.post('vv.php',{a:'yy'},function(msg){
             var x = eval('('+msg+')');
             $.each(x,function(i,m){
                 $('table').append('<tr><td>'+m.status+'</td><td>'+m.msg+'</td></tr>');
             })
         })
     })
 })
 </script>

vv.php部分:

 <?php
 $a = !empty($_POST['a'])?$_POST['a']:0;
 if($a=='yy'){
     $arr =  array(
         array('status' => 0, 'msg' => '未知错误'),
         array('status' => 1, 'msg' => '未知错误22')
     );
     echo json_encode($arr);
 }
 ?>
