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);以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
