jquery treegrid实例

前台jqurey代码

function organDatagrid(){
	$organ_treegrid  = $('#organ_treegrid').treegrid({
    url:ctx+'/petition/petition-info/organ-datagrid',
    fit:true,
    fitColumns:false,//自适应列宽
    striped:true,//显示条纹
    rownumbers:true,//显示行数
    nowrap : false,
    border : false,
    singleSelect:true,
    showFooter : true,
    remoteSort:false,//是否通过远程server对数据排序
/*  sortName:'orderNo',//默认排序字段
    sortOrder:'asc',//默认排序方式 'desc' 'asc' */
    idField : 'id',
    treeField:"name",
/*  frozenColumns:[[
        {field:'name',title:'机构名称',200},
        {field:'sysCode',title:'机构系统编码',120}
    ]], */
    columns:[[
        {field:'id',title:'主键',hidden:true,sortable:true,align:'right',80},
        {field:'name',title:'机构名称',400},
        {field:'pcount',title:'信訪数量',120},
        {field:'scale',title:'比例',120}
    ]]
   }).datagrid('showTooltip');
}

后台业务代码

	@RequestMapping(value = {"organ-datagrid"})
	@ResponseBody
	public Datagrid<Map> getPetitionOrgan(@RequestParam(value = "startTime", required = false)Date startTime,
			@RequestParam(value = "endTime", required = false)Date endTime) throws Exception {
		List<Map> list = null;
                //此处省略业务代码		
		Datagrid<Map> dg= new Datagrid<Map>(list.size(), list);
        return dg;
	}

dataGrid能够不须要用DataGrid类来构造，仅仅需返回list；treeGrid必须返回DataGrid类这种构造数据，才干有树形显现。
