easyui searchBox 搜索框

<body class="easyui-layout" data-options="fit:true"><div data-options="region:'center',border:false"style="overflow: hidden;"><table id="datagrid"></table></div><div id="search" style="display:inline;padding-top:10px;"><!-- 这里的padding-top是让搜索栏向下点，也就是与"添加"等按钮对齐，但在HTML里面不好用，在jsp页面中已测试可用 --><input id="searchBox" class="easyui-searchbox" searcher="searchData"prompt="请输入查询内容" style="width:300px"></input><div id="searchMenu" style="width:100px"></div></div><div id="menu" class="easyui-menu" style="width:120px;display: none;"><div onclick="append();" data-options="iconCls:'icon-add'">增加</div><div onclick="removeData();" data-options="iconCls:'icon-remove'">删除</div><div onclick="edit();" data-options="iconCls:'icon-edit'">编辑</div></div></div></body>

2.js

//循环列名，生成搜索的下拉列表 var fields =  $('#datagrid').datagrid('getColumnFields'); var muit=""; for(var i=0; i<fields.length; i++){ var opts = $('#datagrid').datagrid('getColumnOption', fields[i]);muit += "<div name='"+ fields[i] +"'>"+ opts.title +"</div>";};$('#searchMenu').html($('#searchMenu').html()+muit);$('#searchBox').searchbox({ menu:'#searchMenu' }); //获取生成的搜索框var tSearch = $("#search"); //将生成好的搜索框放入工具栏 $(".datagrid-toolbar").append(tSearch);

3. 搜索方法

function searchData(value,name){ $('#datagrid').datagrid('load', { "searchKey": name, "searchValue": value });}

4.searchKey是要查询的字段名，searchValue是这个字段名的值，后台接收到这两个参数然后自己拼接sql查询

a.这是查询总记录的

String hql = "select count(*) from PageImg p where 1=1";if (!UtilTool.isNull(pageImgModel.getSearchKey()) && !UtilTool.isNull(pageImgModel.getSearchValue())) {hql = hql + " and p." + pageImgModel.getSearchKey() + " like '%" + pageImgModel.getSearchValue() + "%'";}

b.这是查询列表

private List<PageImg> find(PageImgModel pageImgModel) {String hql = "from PageImg p where 1=1 ";List<Object> values = new ArrayList<Object>();hql = addWhere(pageImgModel, hql, values);if (pageImgModel.getSort() != null && pageImgModel.getOrder() != null) {hql += " order by " + pageImgModel.getSort() + " " + pageImgModel.getOrder();}return pageImgDAO.find(hql, values, pageImgModel.getPage(), pageImgModel.getRows());}private String addWhere(PageImgModel imgModel, String hql, List<Object> values) {if (!UtilTool.isNull(imgModel.getSearchKey()) && !UtilTool.isNull(imgModel.getSearchValue())) {hql += "and p." + imgModel.getSearchKey() + " like ? ";values.add("%" + imgModel.getSearchValue().trim() + "%");}return hql;}

封装的DAO

/** * 查询集合(带分页) *  * @param hql * @param param * @param page * @param rows * @return */public List<T> find(String hql, List<Object> param, Integer page, Integer rows);public List<T> find(String hql, List<Object> param, Integer page, Integer rows) {if (page == null || page < 1) {page = 1;}if (rows == null || rows < 1) {rows = 10;}Query q = this.getCurrentSession().createQuery(hql);if (param != null && param.size() > 0) {for (int i = 0; i < param.size(); i++) {q.setParameter(i, param.get(i));}}return q.setFirstResult((page - 1) * rows).setMaxResults(rows).list();}

效果图一张：（发现设置了哪个padding还是不能让搜索框和按钮对齐）
