我正在使用ExtJs 4.1网格并添加了组功能。在商店中我指定了groupField和分组功能正常工作。但是当网格呈现时,组标题显示为组:组名称“。如何防止'组'关键字出现在组标题中(在下图中突出显示)。< / p>
Ext.require(['Ext.data.*', 'Ext.grid.*']);
Ext.onReady(function() {
Ext.regModel('Teams', {
fields: ['name', 'sport']
});
var teamStore = new Ext.data.Store({
model: 'Teams',
sorters: ['sport','name'],
groupField: 'sport',
data: [
{ name: 'Aaron', sport: 'Table Tennis' },
{ name: 'Aaron', sport: 'Football' },
{ name: 'Abe', sport: 'Basketball' },
{ name: 'Tommy', sport: 'Football' },
{ name: 'Tommy', sport: 'Basketball' },
{ name: 'Jamie', sport: 'Table Tennis' },
{ name: 'Brian', sport: 'Basketball' },
{ name: 'Brian', sport: 'Table Tennis' }
]
});
var grid = new Ext.grid.GridPanel({
renderTo: Ext.getBody(),
store: teamStore,
width: 400,
height: 300,
title: 'Sports Teams',
features: [{
ftype: 'grouping'
}],
headers: [{
text: 'Name',
flex: 1,
dataIndex: 'name'
},{
text: 'Sport',
dataIndex: 'sport'
}]
});
});

使用groupHeaderTpl
配置解决您的问题。请参考以下示例代码以供参考。
注意:参考Ext.grid.feature.Grouping
类创建区域,参见groupHeaderTpl
config。当前代码将按预期工作。
使用网格中的组列名称
//groupHeaderTpl: '{columnName}: {name} ({rows.length} Item{[values.rows.length > 1 ? "s" : ""]})',
网格中没有组列名称
groupHeaderTpl: '{name} ({rows.length} Item{[values.rows.length > 1 ? "s" : ""]})',
我希望这会对你有所帮助。复制下面的代码并将其粘贴到https://fiddle.sencha.com/并查看输出。
我的示例代码:
Ext.require(['Ext.data.*', 'Ext.grid.*']);
Ext.onReady(function() {
// wrapped in closure to prevent global vars.
Ext.define('Restaurant', {
extend: 'Ext.data.Model',
fields: ['name', 'cuisine']
});
var restaurants = Ext.create('Ext.data.Store', {
storeId: 'restaraunts',
model: 'Restaurant',
groupField: 'cuisine',
sorters: ['cuisine','name'],
data: [{
name: 'Cheesecake Factory',
cuisine: 'American'
},{
name: 'University Cafe',
cuisine: 'American'
},{
