本文实例为大家分享了bootstrap实现下拉框搜索展示的具体代码，供大家参考，具体内容如下
1.第一个下拉框代码
<div class="btn-group col-sm-3 col-xs-6 util-btn-margin-bottom-5 quick-search">
<!--快速查询-->
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-search"></i></span>
<select data-filter-type="2" name="copyfrom" class="form-control select2" data-validate="notempty" style="visibility: hidden;" data-field="name" data-placeholder="搜索数据资源">
<option value="">请选择数据资源</option>
<optgroup label="UNESCO二类中心">
<#list data.copyfromList as entity>
<#if (entity.type"${entity.alias!}" <#if (param.copyfrom"科技动态与进展">
<#list data.copyfromList as entity>
<#if (entity.type"${entity.alias!}" <#if (param.copyfrom"其他">
<#list data.copyfromList as entity>
<#if (entity.type"${entity.alias!}" <#if (param.copyfrom"htmlcode">
<div class="btn-group col-sm-3 col-xs-6 util-btn-margin-bottom-5 quick-search">
<!--快速查询-->
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-search"></i></span>
<select data-filter-type="2" name="cid" class="form-control select2" data-validate="notempty" style="visibility: hidden;" data-field="name" data-placeholder="搜索栏目名称">
<option value=""></option>
<#list data.categories as entity>
<option value="${entity.id}" <#if (param.cid"htmlcode">
bindEvents:function(){
var self = this, dom = self.element;
$('select[name="copyfrom"]', dom).change(function(event){
self.params.copyfrom = $(this).val();
var url = self.formatParams(self.params);
window.location.href = "cekasp_article.htm" + url;
});
$('select[name="cid"]', dom).change(function(event){
self.params.cid = $(this).val();
var url = self.formatParams(self.params);
window.location.href = "cekasp_article.htm" + url;
});
}
formatParams:function(params){
var self = this;
var url = "";
for(var param in params){
if(params[param]){
url += param + "=" + params[param] + "&";
}
}
if(url.length > 0){
url = "" + url.substring(0,url.length-1);
}
return url;
}
4.后台java部分代码（接收参数，然后过滤器根据参数得到想要的结果）
String categoryId = request.optString("cid");
if (!ValidateUtil.isNull(categoryId)) {
// 加载栏目信息
JSONObject jsonCategory = toJSONObject(adminService.loadById(CekaspCategory.class, categoryId));
response.put("category", jsonCategory);
param.addFilter("id", FilterType.IN, articleIdList, 1);
}
String copyfrom = request.optString("copyfrom");
if (!ValidateUtil.isNull(copyfrom)) {
param.addFilter("copyfrom", FilterType.EQUALS, copyfrom);
}
List<CekaspArticle> articleList = adminService.list(CekaspArticle.class,param);
