How to change Ext js store data dynamically
提问by Surya Prakash Tumma
I have a combobox which looks like below
我有一个如下所示的组合框
{
xtype:'combo',
fieldLabel:'Test',
store:['a','b']
}
Without creating Ext store object I am assigning the array to store and it is displaying the values fine.
在不创建 Ext 存储对象的情况下，我将数组分配给存储，并且它显示的值很好。
At some action i want to update the store with ['d','e']
在某些操作中，我想用 ['d','e'] 更新商店
I have tried by assigning the new values to store like below
我尝试通过分配新值来存储，如下所示
comboObje.store=['d','e'];
but it is not updating the values.
但它没有更新值。

You can create a new store using bindStoreor just load new data to the existing store using loadData:
您可以使用以下命令创建新商店bindStore或仅将新数据加载到现有商店loadData：
combo.store.loadData(['d', 'e'].map(function(item){ return [item]; }));

In version 5.* and higher you can use:
在 5.* 及更高版本中，您可以使用：
comboObje.setStore(['d','e']);
This doesn't work in previous versions.
这在以前的版本中不起作用。
Paste the following code into a Sencha Fiddleas a 'proof-of-concept':
将以下代码粘贴到Sencha Fiddle 中作为“概念验证”：
Ext.application({
name : 'Fiddle',
launch : function() {
var panel = Ext.create('Ext.form.Panel', {
title: 'test',
items: [{
xtype:'combo',
fieldLabel:'Test',
store:['a','b']
}],
renderTo: Ext.getBody()
});
panel.down('combo').setStore(['d','e']);
}
});

Try this:
试试这个：
comboObje.getStore().loadData([{'field1': 'd'}, {'field1': 'e'}]);
When you assign an array to 'store' config, ExtJS automatically generates field names.
当您将数组分配给“存储”配置时，ExtJS 会自动生成字段名称。
