关于jquery获取服务器端xml数据

其实这个很简单，但是有时候简单的东西会让你犯一些低级错误。

今天写了个spring mvc 的服务器端接口，主要是用来共享一些数据库数据。

请求字段：http://localhost:8080/XXXXX/data/listrealdata?m_pname=%25%25&m_pp=%25%25&m_ggxh=%25%25&m_xsht=%25%25&m_pid=%25%25

返回数据：

                                });
                            }
                        });
                   })  
            }) 
    </script>
</head>
<body>
<form id="form1" action="#">  
    <p>分页测试:</p>  
    m_pname:<input id="m_pname" name="m_pname" type="text" value="%%"/>
    m_pp:<input id="m_pp" name="m_pp" type="text" value="%%"/>
    m_ggxh:<input id="m_ggxh" name="m_ggxh" type="text" value="%%"/>
    m_xsht:<input id="m_xsht" name="m_xsht" type="text" value="%%"/>
    m_pid:<input id="m_pid" name="m_pid" type="text" value="%%"/><br/>
    <p><input type="Button" id="send" value="提交"/></p>  
    </form>  
    <div class='comment'>返回数据：</div>  
    <div id="resText" ></div>

</body>
</html>

一个很简单的东西，以上的代码是解决了问题的：

问题现象是，我提交后，网页提示error。

解决办法是：

<p><input type="button" id="send" value="提交"/></p>
改成

<p><input type="Button" id="send" value="提交"/></p>

希望；雷同问题的小朋友少走弯路...
