JavaScript实现dropdownlist选定值后将选定值的key与value填入两个textbox中

   <script language="javascript" type="text/javascript">
       var txtText0 = "#" + '<%= new DynamicControl(this, "Text0").ClientID%>';//vendor#
       var txtText1 = "#" + '<%= new DynamicControl(this, "Text1").ClientID%>';//vendor name
       var dplVendor = "#" + '<%= new DynamicControl(this, "FUVendor").ClientID%>';

       $(function () {

           $(dplVendor).change(function () {
               $(txtText0).val($(dplVendor).val());
               $(txtText1).val($(dplVendor).find("option:selected").text());
           }); 

       });

   </script>
