基于bootstrap实现多个下拉框同时搜索功能

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.type == '1')>
          <option value="${entity.alias!}" <#if (param.copyfrom?? && param.copyfrom == entity.alias)>selected</#if>>${entity.alias!}</option>
          </#if>
          </#list>
         </optgroup>
         <optgroup label="科技动态与进展">
          <#list data.copyfromList as entity>
          <#if (entity.type?? && entity.type == '7')>
          <option value="${entity.alias!}" <#if (param.copyfrom?? && param.copyfrom == entity.alias)>selected</#if>>${entity.alias!}</option>
          </#if>
          </#list>
         </optgroup>
         <optgroup label="其他">
          <#list data.copyfromList as entity>
          <#if (entity.type?? && entity.type == '8')>
          <option value="${entity.alias!}" <#if (param.copyfrom?? && param.copyfrom == entity.alias)>selected</#if>>${entity.alias!}</option>
          </#if>
          </#list>
         </optgroup>
        </select>
       </div>
      </div>

2.第二个下拉框代码

<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="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="${entity.id}" <#if (param.cid?? && param.cid == entity.id)>selected</#if>>${entity.id} - ${entity.name}</option>
         </#list>
        </select>
       </div>
      </div>

3.后台js代码（url 参数整理）

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);
