php页面：

<?php
 header("Content-type:text/html;charset=utf-8");
         $username = $_POST[&#39;username&#39;];
         $age = $_POST[&#39;age&#39;];
         $job = $_POST[&#39;job&#39;];
         $json_arr = array("username"=>$username,"age"=>$age,"job"=>$job);
         $json_obj = json_encode($json_arr);

使用post方式

<script type="text/javascript">
  $(function(){
   $("#send").click(function(){
       var cont = {username:$("input")[0].value,age:$("input")[1].value,job:$("input")[2].value};
       var url = &#39;ab.php&#39;;
       $.post(url,cont,function(data){
        var res = eval("(" + data + ")");//转为Object对象
       var str = res.username + res.age + res.job;
     $("#result").html(str);
    });
   });  
  });
 </script>
