jquery easyui分页相关说明
$(function(){$('#test').datagrid({ title:'分类',//表格标题 iconCls:'icon-save',//表格图标 nowrap: false,//是否只显示一行，即文本过多是否省略部分。 striped: true,url:'../../linkadminjson/sortsAction.do', //action地址sortName: 'parentID',sortOrder: 'desc',idField:'nodeID',pageNumber:1,//当前页码pageList:,//每一页显示的记录数,对就后台接收的rowsfrozenColumns:[[]],columns:[[{field:'title',title:'名称',width:150},{field:'isindex',title:'首页显示',width:60},{field:'ishot',title:'热门',width:60},{field:'isnew',title:'最新',width:60},{field:'property',title:'通过审核',width:60}]],pagination:true, //包含分页rownumbers:true,singleSelect:true,toolbar:[{text:'Add',iconCls:'icon-add',handler:function(){alert('add')}},{text:'Cut',iconCls:'icon-cut',handler:function(){alert('cut')}},'-',{text:'Save',iconCls:'icon-save',handler:function(){alert('save')}}]});});1.jquery easyui分页方式为ajax方式分页,所以需要再后台打印json格式的数据
{"rows":[ {"hits":0,"id":62,"imgurl":"","info":"？？？？？？？\r\n","ishot":0,"isindex":0,"isnew":0,"property":1,"puttime":"2010-10-03","sid":0,"sortnum":0,"title":"？？？？？？","url":"tt"}, {"hits":0,"id":63,"imgurl":"","info":"？？？？？\r\n","ishot":0,"isindex":1,"isnew":0,"property":1,"puttime":"2010-10-03","sid":0,"sortnum":0,"title":"？？？？？","url":"？？"}],"total":8}
rows: 当前显示的数据集
total:总记录数,这里记录数不是rows中的记录数,而是通过相应的hql (如:select count(*) from Sort)语句得来的记录数.
2.遇到hibernate的实体集不能转换成json格式的相关处理
如果是日期格式不能转换可以用如下方式(先去掉日期字段,看是否为日期字段不能转换):
json日期处理类
package com.dao.json;import java.text.DateFormat;import java.text.SimpleDateFormat;import java.util.Date;import net.sf.json.JsonConfig;import net.sf.json.processors.JsonValueProcessor;import net.sf.json.util.CycleDetectionStrategy;public class DateJsonValueProcessor implements JsonValueProcessor { public static final String DEFAULT_DATE_PATTERN = "yyyy-MM-dd HH:mm:ss"; private DateFormat dateFormat; /** * 构造方法. * * @param datePattern 日期格式 */ public DateJsonValueProcessor(String datePattern){ try { dateFormat = new SimpleDateFormat(datePattern); } catch (Exception ex) { dateFormat = new SimpleDateFormat(DEFAULT_DATE_PATTERN); } } public Object processArrayValue(Object value, JsonConfig jsonConfig) { return process(value); } public Object processObjectValue(String key, Object value, JsonConfig jsonConfig) { return process(value); } private Object process(Object value) { return dateFormat.format((Date) value); } }
action中json格式转换代码相应的代码:
JSONObject resultObj=new JSONObject();JsonConfig cfg = new JsonConfig(); cfg.registerJsonValueProcessor(java.util.Date.class,new DateJsonValueProcessor("yyyy-MM-dd")) ; resultObj.put("rows",JSONArray.fromObject(page.getResult(),cfg));resultObj.put("total", page.getRowCount());//当分页建立时设置记录的总数量
3.action中需要接收并做出相应处理的几个参数说明
private int page; //当前页码,接收前台pageList:[...]中的相应的单个数据
private int rows;//每一页显示的行数
页:
[1]
