      dataType:'json',
      data:cont,
      success:function(data){
       var str = data.username + data.age + data.job;
       $("#result").html(str);

php page:

<?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);
    echo $json_obj;

Use post method

<script type="text/javascript">
 $(function(){
 $("#send").click(function(){
   var cont = {username:$("input")[0].value,age:$("input")[1].value,job:$("input")[2].value};
   var url = 'ab.php';
   $.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>
