javascript - show the selected value in dropdown on edit jsp page on page load (Spring MVC) -


i want show selected value in dropdown on page load. edit page shows value, country. user belongs usa, usa should selected default on page load. can use javascript or jquery.

i found few on internet scriplets (<% %>) , don't want use them.

i passing list has id , value. have id in object. can write code introducing loop in jsp , showing value, may doing mistake there. wanted know if there better way this.

i using spring mvc.

thanks.

"now user belongs usa, usa should selected default on page load.". know before hand user belongs country.

assuming have pojo country as:

    public class country{          string countryname;         string countryid;         //setters , getters     }      public class yourform{         list<country> countrylist;         string selectedcountryid;         ...         //setters , getters     }

in controller method delegates jsp:

    ...     yourform form = new yourform();     //set countrylist form      //set  country user belongs - selectedcountryid - since know before hand user belongs country.     model.addattribute("yourform", form):     ...

now access in jsp as:

    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>     <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>     <head>         <meta http-equiv="content-type" content="text/html; charset=windows-1252">     </head>     <body>     <form:form id="yourform" modelattribute="yourform" method="post">      <tr>         <td width="50%" class="label">             <form:select id="countryid" path="selectedcountryid" title='select country'>                 <option value="">please select</option>                 <form:options items="${countrylist}" itemvalue="countryid" itemlabel="countryname"/>             </form:select>         </td>     </tr>     </body>

since selectedcountryid set in controller see country auto selected in jsp.
