bootstrap实现多选项及回显

1.前端

<link rel="stylesheet" href="${ctxStatic}/js/bootstrap-select-1.12.2/dist/css/bootstrap-select.css">
<script src="${ctxStatic}/js/bootstrap-select-1.12.2/dist/js/bootstrap-select.js"></script>

 

<div class="form-group">
    <div class="input-group">
        <span class="input-group-addon gray-bg text-right">区域划分:</span>
        <select title="请选择区域划分" id="areas" name="areas" class="selectpicker show-tick form-control w164" multiple data-live-search="false">
             <c:forEach items="${areas}" var="area">
                  <option value="${ area.code}" class="area">${area.name}</option>
             </c:forEach>
        </select> 
    </div>
 </div>

//判断是否选中区域类别
var area = '${fns:toJson(childBaseinfo.areas)}';
if(area && area != "\"\""){
    $("#areas").selectpicker('val',JSON.parse(area));
}

 

后端：

List<SysCommunity> areas = sysCommunityService.findList(new SysCommunity());
model.addAttribute("areas", areas);
