easyUI下拉框表格扩展(实现搜索功能)[easyUI+java]

一个小demo:easyUI下拉框表格扩展(实现搜索功能)

下拉框表格里由于数据过多,需要有一个搜索来快速定位到用户想要的数据;

效果图:

目录结构:

html部分代码:

<table width="500">
	<tr>
		<td>引用:</td>
        <td class="height=25;width=350">
        	<div style="width:350px;height:20px;">
           	<select  id="queryTableName" name="tableName" class="easyui-combogrid" required="true" missingMessage="该项为必填!"></select>  
        	</div>
        </td>
	</tr>
</table>

js代码:

$(function(){
	var html = '<div id="reportComboGridTb">';
	html += '<form id="reportComboGridTbform">';
	html += '<div style="padding-left: 5px;display: inline-block;"><label>报表编码或名称:</label><input id="queryReportCodeOrReportName" class="easyui-textbox"style="width:96px;"data-options="prompt:\'报表编码/报表名称\'"/></div>';
	html += '<div style="padding-left: 5px;display: inline-block;"><label>报表类型:</label><select id="reportDisplayTypeComboBox"name="reportDisplayType"class="easyui-combobox"style="width:96px;"data-options="prompt:\'报表类型\'"></select>';
	html += '<div style="padding-left: 1px; display: inline-block;"><form>';
	html += '<a href="javascript:void(0);" class="easyui-linkbutton" data-options="iconCls:\'icon-search\'" id="queryReport">查询</a>';
	html += '<a href="javascript:void(0);" onclick="javascript:void(0);" class="easyui-linkbutton" data-options="iconCls:\'icon-redo\'" id="resetBtn">重置</a>';
	html += '</div>';
	html += '</div>';
	$('body').append(html);
	$.parser.parse('#reportComboGridTb');
	
	//报表类型的下拉框
	$('#reportDisplayTypeComboBox').combobox({

java Controller代码:

@Controller
@RequestMapping ("/reportDisplayInfo")
public class ReportDisplayInfoController
{
    private final Log _logger = LogFactory.getLog (ReportDisplayInfoController.class);
    // @Resource (name = "reportDisplayInfoService")
    // private IReportDisplayInfoService _reportDisplayInfoService;
    @Autowired
    private IReportDisplayInfoService _reportDisplayInfoService;

    // 分页查询
    @RequestMapping ("/getListReportDisplayInfo")
    @ResponseBody
    public String getReportDisplayInfo (HttpServletRequest request, HttpServletResponse response)
    {
        try// 设置编码集
        {
            request.setCharacterEncoding ("utf-8");
            response.setCharacterEncoding ("utf-8");
        }
        catch (UnsupportedEncodingException e)
        {
            e.printStackTrace ();
        }
        String displayName = request.getParameter ("displayName");
        String displayCode = request.getParameter ("displayCode");
        // 获取分页页数
        String pageNumber = request.getParameter ("pageNumber");
        // 获取分页每页数据条数
        String pageSize = request.getParameter ("pageSize");
        // 如果未获取到行数，则设置默认每页20条数据
        if (StringUtil.isEmpty (pageSize) || "NaN".equals (pageSize))
        {
            pageSize = "10";
        }
        // 如果未获取到页数，则设置默认为第一页
        if (StringUtil.isEmpty (pageNumber) || "NaN".equals (pageNumber))
        {
            pageNumber = "1";
        }
        int rows = Integer.parseInt (pageSize);
        int page = Integer.parseInt (pageNumber);
        int offset = rows * (page - 1);
        int limit = offset + rows - 1;
        ReportDisplayInfo reportDisplayInfo = new ReportDisplayInfo ();
        reportDisplayInfo.setDisplayCode (displayCode);
        Map param = new HashMap ();
        param.put ("displayName", displayName);
        param.put ("displayCode", displayCode);
        Integer totle = _reportDisplayInfoService.queryDataCount (param); // 得到总页数
        param.put ("startNumber", String.valueOf (offset));
        param.put ("endNumber", String.valueOf (limit));
        List <ReportDisplayInfo> list = _reportDisplayInfoService.queryReportDisplayInfoByPage (param);
        Map <String, Object> jsonMap = new HashMap <String, Object> ();

        jsonMap.put ("total", totle);// total键
        jsonMap.put ("rows", list);// rows键 存放每页记录 list
        JsonConfig config = new JsonConfig ();
        config.registerJsonValueProcessor (Date.class, new JsonDateValueProcessor ("yyyy-MM-dd HH:mm:ss"));
        return JSONArray.fromObject (list, config).toString ();
    }

分页sql:

<!-- 分页查询 -->
	<select id="queryReportDisplayInfoByPage" 
		parameterType="java.util.Map" 
		resultType="ReportDisplayInfo">
			select *  
		       from (SELECT ROWNUM rn,T.* 
					from  (select 
					  <include refid="reportDisplayInfo" /><!--这里是引用了字段别名,保证与java实体类的属性一致,实际就是查所有-->
					  from BR_ReportDisplayInfo 
					  	<where>
				         	<if test="displayCode!=null and displayCode!=''">  
				                and REPORTDISPALYCODE = #{displayCode} 
				            </if>  
				            <if test="displayName!=null and displayName!=''">  
				                and REPORTDISPALYNAME like '%'||#{displayName}||'%'  
				            </if> 
					    </where>
					  order by updateTime DESC)T
				<![CDATA[where ROWNUM<=#{endNumber}) 
		      where rn >=#{startNumber}]]>
	</select>

serivce什么的就不摆了,至少我自己看够了
