请教一个输入数字后判断的问题
C# code


<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>无标题页</title>
     <script src="../../js/jquery.js" type="text/javascript"></script>
        <script type="text/javascript">
       $(document).ready(function(){
       var txtOne=document.getElementById("txtRedOne");
       if(txtOne<10)
       {
        txtOne="0"+txtOne;
       }
       }
        </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:TextBox ID="txtRedOne" runat="server" Text=""   onkeyup="if(isNaN(value))execCommand('undo')" MaxLength="12" 
                    BorderStyle="None"></asp:TextBox>
    </div>
    </form>
</body>
</html>
问题:当我输入数字小于10的时候,前面加0,例如,我输入数字5,当鼠标移出,就会变为05!
