DropDownList 控制日期控件显示格式

代码如下：

前台：

 <script src="../js/My97DatePicker/WdatePicker.js" type="text/javascript"></script>

     <script type="text/javascript">

         $(document).ready(function () {

             $('#txtStartTime').bind('focus', function () { WdatePicker() });

             $('#txtEndTime').bind('focus', function () { WdatePicker() });

         });  

         function GetDate() {

             var obj = document.getElementById("ddlType");

             if (obj.value == "Month") {

                 $("#txtStartTime").unbind('focus').bind('focus', function () { WdatePicker({ dateFmt: 'yyyy-MM' }); });

                 $("#txtEndTime").unbind('focus').bind('focus', function () { WdatePicker({ dateFmt: 'yyyy-MM' }); });

             }

             else {

                 $("#txtStartTime").unbind('focus').bind('focus', function () { WdatePicker({ dateFmt: 'yyyy-MM-dd' }); });

                 $("#txtEndTime").unbind('focus').bind('focus', function () { WdatePicker({ dateFmt: 'yyyy-MM-dd' }); });

             }

         

         }

                    

     </script>

  <input id="txtStartTime" readonly="readonly" style='width:100px' clientidmode="Static" type="text" runat="server"/>

                            <input id="txtEndTime" readonly="readonly"  style='width:100px' clientidmode="Static" type="text" runat="server"/>

后台：

 ddlType.Attributes.Add("onchange ", "GetDate()");
