我有两组按钮(在 Extjs 4.1 中),一次只能检查一组。问题是我希望在开始时检查其中一个(当网格加载时)。代码如下:
{
xtype : 'checkboxgroup',
store : checked,
columns : 3,
vertical : false,
singleSelect: true,
items : [
{
xtype: 'button',
text: 'name',
width: 75,
toggleGroup: 'mygroup',
enableToggle: true,
listeners: {
click: function(th) {
//this == the button, as we are in the local scope
checked = [1,0,0];
}}
}, {
xtype: 'button',
text: 'buyer_member_id',
width:100,
toggleGroup: 'mygroup',
enableToggle: true,
listeners: {
click: function(th) {
//this == the button, as we are in the local scope
checked = [0,1,0];
}}
}, {
xtype: 'button',
text: 'id',
width: 50,
toggleGroup: 'mygroup',
enableToggle: true,
listeners: {
click: function(th) {
//this == the button, as we are in the local scope
checked = [0,0,1];
}}
}
]}
我在 Sencha 论坛中找到了一些帮助,但我无法解决问题。
