后台写法：List<LabelValueBean> roleList = new ArrayList<LabelValueBean>(); request.setAttribute("roleList", roleList); dto = ctlBL.getUserRolesNotInProcess(dto); List<UserRoleInfo> list = dto.getUserRoleList(); for(UserRoleInfo info : list){ //前面的是页面显示的值，后面的是要存储的值 roleList.add(new LabelValueBean(info.getRolename(), info.getRoleid().toString())); } if(roleList.isEmpty()){ roleList.add(new LabelValueBean("", "")); }页面写法：<html:select property="prroleid" style="width: 120px;" errorStyleClass="inputError imeActive" tabindex="2" οnchange="changePrRolename()"> <html:options collection="roleList" property="value" name="" labelProperty="label"/> </html:select>
原理就是在后台做一个LabelValueBean的list,发到前台的option处,通过标签自动进行值的处理~~~
