我有这样的观点:
Ext.define('MyApp.view.CustomersList', {
extend: 'Ext.grid.Panel',
store: Ext.create('MyApp.store.Customers'),
columns: [
{
width: 150,
dataIndex: 'customerName',
text: 'CustomerName'
},
{
width: 200,
dataIndex: 'customerNumber',
flex: 1,
text: 'CustomerNumber'
}
]
});
我明确地实例化了一个商店,但是当我在Viewport中加载这个视图时,我发现了这样的错误:
Uncaught TypeError: Expecting a function in instanceof check, but got function constructor() {
// Opera has some problems returning from a constructor when Dragonfly isn't running. The || null seems to
// be sufficient to stop it misbehaving. Known to be required against 10.53, 11.51 and 11.61.
return this.constructor.apply(this, arguments) || null;
}

答案 0 :(得分:2)
Ext.define('MyApp.view.CustomersList', {
extend: 'Ext.grid.Panel',
initComponent: function(){
this.store = Ext.create('MyApp.store.Customers');
this.columns = [
{
width: 150,
dataIndex: 'customerName',
text: 'CustomerName'
},
{
width: 200,
dataIndex: 'customerNumber',
flex: 1,
text: 'CustomerNumber'
}]
this.callParent();
}
});
希望它有所帮助!!
