我是extjs的新手,任何人都可以帮助我。
当我双击树状面板中的某个项目时,它应该在网格面板中添加而不会在树状面板上进行任何更改。

您可以在treepanel上放置'itemdblclick'事件的侦听器,以从双击的项目的原始属性中获取数据。然后,通过引用底层网格的存储,只需使用商店的'loadRawData'方法附加该数据对象。以下是基于Sencha网站示例的代码示例:
var store = Ext.create('Ext.data.TreeStore', {
root: {
expanded: true,
children: [
{ text: "School Friends", expanded: true, children: [
{ text: "Mike", leaf: true, name: "Mike", email: "mike@stackoverflow.com", phone: "345-2222"},
{ text: "Laura", leaf: true, name: "Laura", email: "laura@stackoverflow.com", phone: "345-3333"}
] },
{ text: "Facebook Friend", expanded: true, children: [
{ text: "Steve", leaf: true, name: "Steve", email: "steve@stackoverflow.com", phone: "345-2222"},
{ text: "Lisa", leaf: true, name: "Lisa", email: "lisa@stackoverflow.com", phone: "345-3333"}
] },
]
}
});
Ext.create('Ext.tree.Panel', {
title: 'All My Friends',
width: 200,
height: 150,
store: store,
rootVisible: false,
renderTo: Ext.getBody(),
listeners : {
itemdblclick : function(tree, record, index){
Ext.getStore('simpsonsStore').loadRawData([record.raw], true);
}
}
});
Ext.create('Ext.data.Store', {
storeId:'simpsonsStore',
fields:['name', 'email', 'phone'],
data:{'items':[
{ 'name': 'Bart', "email":"bart@simpsons.com", "phone":"555-222-1234" },
{ 'name': 'Homer', "email":"home@simpsons.com", "phone":"555-222-1244" },
{ 'name': 'Marge', "email":"marge@simpsons.com", "phone":"555-222-1254" }
]},
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'
}
}
});
Ext.create('Ext.grid.Panel', {
title: 'Best Friends',
store: Ext.data.StoreManager.lookup('simpsonsStore'),
columns: [
{ text: 'Name', dataIndex: 'name' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone' }
],
height: 200,
width: 400,
renderTo: Ext.getBody()
});
