动态表单问题
我做过了个依据select选项动态显示input的页面,js代码如下
JScript code

        $(document).ready(function(){
             $("#orderPrice").hide();
             $("#orderQuantity").hide();
        });
    function typeChange(value){
         if(value == 4){
                 $("#orderPrice").show();
             $("#orderQuantity").show();
         }
         else{
             $("#orderPrice").hide();
             $("#orderQuantity").hide();
         }       
    }    


包含这个jsp页面的html代码如下:
HTML code

<body>
<table cellpadding="0" cellspacing="0">
    <tr>
        <td align="left">
            <table class="tbl_layout" cellpadding="0" cellspacing="0">
                <colgroup>
                    <col width="2%"/>
                    <col width="98%"/>
                </colgroup>
                <tr>
                    <td rowspan="4">&nbsp;</td>
                    <td>
                        <%@include file="header.jsp" %>
                    </td>
                </tr>
                <tr>
                    <td>
                        <br/>
                        <table cellpadding="0" cellspacing="0">
                            <colgroup>
                                <col width="20%"/>
                                <col width="80%"/>
                            </colgroup>
                            <tr>
                                <td class="tbl_header">
                                    <%@include file="menu.jsp" %>
                                </td>
                                <td class="tbl_header">
                                    <iframe src="${foaPath}/stock_portfolio_init.htm" scrolling="no" width="100%" height="159px" valign="top" name="mainFrame" id="mainFrame" frameborder="0" ></iframe>
                                </td>
                            </tr>
                        </table>
                    </td>
                </tr>
                <div id="footerdiv">
                <tr>
                    <td>
                        <table cellpadding="0" cellspacing="0">
                            <tr>
                                <td>
                                    <br/>
                                    <br/>
                                    <iframe src="${foaPath}/realtime_quote_search.htm" scrolling="no" width="100%" height="60px" valign="top" name="rtqpFrame" id="rtqpFrame" frameborder="0" ></iframe>
                                </td>
                            </tr>
                            <tr>
                                <td>
                                    <%@include file="footer.jsp" %>
                                </td>
                            </tr>
                        </table>
                    </td>
                </tr>
                </div>
            </table>
        </td>
    </tr>
</table>
</body>



现在碰到的问题就是当下拉框选到4的时候两个input能显示出来,但是
