select下拉框数据回显

前台页面

<select class="select" name="operatorId" id="operatorId" style="height: 21px;" >

                    <option value="">所属运营商</option>

                    <c:forEach items="${operatorList}" var="operator">

                        <option value="${operator.operatorId}" <c:if test="${operator.operatorId==operatorId}">selected </c:if> >${operator.operatorName}</option>

                    </c:forEach>

                </select>

后台用ModelMap  来回显到前台页面上.

public String advertisingList(HttpServletRequest request, ModelMap model) {

        //这个map是传入的值,进行查询.

        Map<String, Object> map = new HashMap<>();

        String operatorId = request.getParameter("operatorId");

        String adClass = request.getParameter("adClass");

        String adName = request.getParameter("adName");

        map.put("operatorId", operatorId);

        map.put("adClass", adClass);

        map.put("adName", adName);

        //查询所有广告位,进行分页查询.

        PageUtil page = this.buildParam(request, map);

        List<Map<String,Object>> operatorList=operatorService.getAllOperator();

        model.put("operatorList", operatorList);

        List<ChargeAdDTO> chargeAdList = chargeAdService.selectAllChargeAdForPage(map);

        model.put("chargeAdList", chargeAdList);

        //前台数据回显

        model.put("operatorId", operatorId);

        model.put("adClass", adClass);

        model.put("adName", adName);

        model.put("pageBar", page.getToolsMenu());

        return "/manage/advertising/advertising_list";

    }

静态数据回显:

 <span class="select-box inline radius" >

                <select class="select" id="adClass" name="adClass" style="height: 21px;width:100px">

                    <option value='' >广告位类型</option>

                    <option value='0'>图片轮播</option>

                    <option value='1'>视频轮播</option>

                </select>

            </span>

$(function(){
$("#adClass").find("option[value='${adClass}']").attr("selected",'selected');
})

文本框的话,直接加上,value="{}"就好了.

<input type="text" class="input-text radius" style="width:150px" placeholder="请输入广告位名称"  name="adName" id="adName" value="${adName}">
