jQuery.Ajax()的data参数类型详解

<form id='addForm' action='UserAdd.action' type='post'>
   <label for='uname'>用户名</label>：<input type='text' name='uname' id='uname'><br>
   <label for='mobileIpt'>手机号：</label><input type='text' name='mobileIpt' id='mobileIpt'><br>
   <label for='birthday'>生日：</label><input type='text' name='birthday'><br>
   <input type='button' value='提交' onclick='addUser()'>
</form>

        }
      }
       
    })

$('#addForm').serializeArray();
//返回数据结构，是json数组，每个对像分别name和value为key，代表这个表单元素的name和value
