Ext.grid.GroupingView

1、Ext.grid.GroupingView
主要配置项：
enableGroupingMenu：是否在表头菜单中进行分组控制，默认为true
groupByText：表头菜单中分组控制的菜单文字，默认为'Group By This Field'

enableNoGroups：是否允许用户关闭分组功能，默认为true
showGroupsText：在表头菜单中启用分组和禁用分组的菜单文字，默认为'Show in Groups'

groupTextTpl：用于渲染分组信息的模板，默认为'{text}'，常用的可选值有：
text：列标题:组字段值
gvalue：组字段的值
startRow：组行索引

enableGrouping：是否对数据分组，默认为true
hideGroupedColumn：是否隐藏分组列，默认为false
ignoreAdd：在向表格中添加数据时是否刷新表格，默认为false
showGroupName：是否在分组行上显示分组字段的名字，默认为true
startCollapsed：初次显示时分组是否处于收缩状态，默认为false

主要方法：
collapseAllGroups()：收缩所有分组行
expandAllGroups()：展开所有分组行
getGroupId( String value )：根据分组字段值取得组id
toggleAllGroups( [Boolean expanded] )：切换所有分组行的展开或收缩状态
toggleGroup( String groupId, [Boolean expanded] )：切换指定分组行的展开或收缩状态


2、Ext.data.GroupingStore
groupField：分组字段

groupOnSort：是否在分组字段上排序，默认为false
remoteGroup：是否远程分组数据，默认为false。如果是远程分组数据，则通过groupBy参数发送分组字段名


3、范例源码

var datas = [[1,"张三",24,"男",new Date(1986,06,09)], [2,"李四",30,"女",new Date(1980,09,13)], [3,"王五",28,"男",new Date(1982,01,10)]];

var person = Ext.data.Record.create([
{name: "personId", mapping: 0},
{name: "personName", mapping: 1},
{name: "personAge", mapping: 2},
{name: "personGender", mapping: 3},
{name: "personBirth", mapping: 4}
]);

var grid = new Ext.grid.GridPanel({
title: "GroupingView实例",
renderTo: "div1",
width: 500,
height: 300,
frame: true,
tbar: [
{
text: "展开/收缩",
iconCls: "search",
handler: function(){
var view = grid.getView();
//var groupId = view.getGroupId("男");
//view.toggleGroup(groupId);
view.toggleAllGroups();
}
}
],

store: new Ext.data.GroupingStore({
reader: new Ext.data.ArrayReader({id:0}, person),
data: datas,
sortInfo: {field:"personId", direction:"ASC"}, //数据排序
groupField: "personGender" //分组字段
}),
view: new Ext.grid.GroupingView({
sortAscText: "升序",
sortDescText: "降序",
columnsText: "表格字段",
groupByText: "使用当前字段进行分组",
showGroupsText: "表格分组",
groupTextTpl: "{text}(共{[values.rs.length]}条)"
}),

columns: [
{id:"personId", header:"编号", width:50, dataIndex:"personId"},
{id:"personName", header:"姓名", width:70, dataIndex:"personName"},
{id:"personAge", header:"年龄", width:45, dataIndex:"personAge"},
{id:"personGender", header:"性别", width:45, dataIndex:"personGender"},

]
});
