ExtJS 4即时更改网格存储 [英] ExtJS 4 Change grid store on the fly
问题描述
例如,我有两个模型:
可以在ExtJS 4中更改网格的商店吗? pre> User = Ext.define('User',{
extends:'Ext.data.Model',
[...],
hasMany:'Product'
});
Product = Ext.define('Product',{
extends:'Ext.data.Model',
[...]
});
和两个网格。
第一个网格与Store使用 User
模型链接,并从后端加载嵌套的json数据,如
{
users:[{
id:1,
products:[
{id:1},
{ id:2}
]
},{
id:2,
产品:[
{id:3},
{id:4} ,
{id:5}
]
}]
}
我想要得到的是当您单击第一个网格中的行时,第二个网格必须显示用户的产品,而不连接到服务器。
我知道的是 user.products();
返回一个 Ext.data.Store
对象。
所以这个想法是将第二个网格的商店更改为 user.products();
,但是没有这样的方法 grid.setStore谢谢提前
我认为一个更好的解决方案是:
grid1.on('itemclick',function(view,record ){
grid2.reconfigure(record.products());
);
Is it posible to change grid's store in ExtJS 4?
For example, i have two models:
User = Ext.define('User',{
extend: 'Ext.data.Model',
[...],
hasMany: 'Product'
});
Product = Ext.define('Product',{
extend: 'Ext.data.Model',
[...]
});
and two grids.
The first grid is linked with Store which uses User
model and loads nested json data from backend, like
{
users: [{
id: 1,
products: [
{id: 1},
{id: 2}
]
}, {
id: 2,
products: [
{id: 3},
{id: 4},
{id: 5}
]
}]
}
All i want to get is when you click on the row in the first grid, the second grid must show products of the user, without connection to the server.
All i know is that user.products();
returns a Ext.data.Store
object.
So the idea is to change second grid's store to user.products();
, but there is no such method grid.setStore()
:-)
Thanks in advance
I think a better solution would be to :
grid1.on('itemclick', function(view, record) {
grid2.reconfigure(record.products());
);
