我與煎茶玩弄並創建了一個清單,商店和模型:煎茶觸摸 - 擴展存儲 - 構造函數調用
主:
Ext.Loader.setConfig({enabled: true});
Ext.application({
viewport: {
autoMaximize: false
},
name: 'Sencha',
launch: function() {
Ext.create('Ext.List', {
fullscreen: true,
store: Ext.create('store.Test', {
}),
itemTpl: '{lastName}, {firstName} Age: {age}'
});
}
});
店:
Ext.define('store.Test', {
extend: 'Ext.data.Store',
model: 'model.User',
data: [
{ firstName: 'Ed', lastName: 'Spencer', age: 30 },
{ firstName: 'Tommy', lastName: 'Maintz', age: 41 },
{ firstName: 'Aaron', lastName: 'Conran', age: 24 },
{ firstName: 'Jamie', lastName: 'Avins', age: 76 }
]
});
型號:
Ext.define('model.User', {
extend: 'Ext.data.Model',
fields: [
{ name: 'firstName', type: 'string' },
{ name: 'lastName', type: 'string' }
]
});
至此,一切正常。
然後,我創建了第二家店,其中有另一個領域'年齡'。我現在想要的是將一個參數「模型」傳遞給商店,以便能夠在不同模型之間「切換」。 我想是這樣的:
店:
Ext.define('store.Test', {
extend: 'Ext.data.Store',
myModel: null,
constructor : function(model) {
myModel = model;
},
model: this.myModel,
data: [
{ firstName: 'Ed', lastName: 'Spencer', age: 30 },
{ firstName: 'Tommy', lastName: 'Maintz', age: 41 },
{ firstName: 'Aaron', lastName: 'Conran', age: 24 },
{ firstName: 'Jamie', lastName: 'Avins', age: 76 }
]
});
,並在主文件:
[...]
store: Ext.create('store.Test', {
model: 'model.UserWithAge'
}),
[...]
不過,谷歌給我:
Uncaught TypeError: Object [object Object],[object Object],[object Object],[object Object] has no method 'getRange'
任何提示我做錯了嗎?
