根據ID填充文本框的實例代碼

前台：
代碼如下：

<script type="text/javascript">
     function func_load_remark(sr_id){
     if(sr_id!=0){
        $.getJSON("loadSrRemark.do?date="+new Date(), {srid:sr_id}, function(srmain){
        $("#bparemark").val(srmain.bpa_remark);
        $("#itdremark").val(srmain.itd_remark);
        $("#bugremark").val(srmain.bu_remark);
        $("#itoremark").val(srmain.ito_remark);
        });
     }else{
        $("#bparemark").val("");
        $("#itdremark").val("");
        $("#bugremark").val("");
        $("#itoremark").val("");
     }
     }
     function check(){
     if($("#srid").val()=="0"){
     alert("請選擇SR_ID!");
     $("#srid").focus();
     return false;
     }
     return true;
     }
     </script>

後台：
代碼如下：

import java.io.PrintWriter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import net.sf.json.JSONSerializer;
import net.sf.json.util.JSONUtils;

import org.apache.struts.action.ActionForward;

import com.aegon_cnooc.framework.base.action.BaseAction;
import com.aegon_cnooc.oa.admin.service.UserService;
import com.aegon_cnooc.oa.ibatis.to.TuOafSrMainTO;
public class LoadSrRemarkAction extends BaseAction{
 private UserService userService;
 public ActionForward executeAction(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response)
   throws Exception {
  String srid=request.getParameter("srid");
  TuOafSrMainTO srMain=userService.getRemarkBySrId(srid);
    response.setContentType("application/json;charset=gbk");
         response.setCharacterEncoding("gbk");
         PrintWriter pw = response.getWriter();
         pw.write(JSONUtils.valueToString(JSONSerializer.toJSON(srMain)));
         pw.flush();
  return null;
 }
 public void setUserService(UserService userService) {
  this.userService = userService;
 }
}
