Extjs defines the instance code of each component separately_extjs

An example I saw online, which contains the component definition copied for your reference:

Copy the code The code is as follows:

Ext.onReady(function(){
var dtCategory=[
['all','所有种类'],
['1','Beverages'],
['2','Condiments'],
['3','Confections'],
['4','Dairy Products'],
['5','Grains/Cereals'],
['6','Meat/Poultry '],
['7','Produce'],
['8','Seafood']
];

}; Question, at this time, you can adjust the tabpanel height and deferredRender and layoutOnTabChange properties by setting
id:'tpProduct',
deferredRender:false, // whether to render all tabs for the first time (default is true)
layoutOnTabChange:true,
//height:300,
//autoTabs:true,
activeTab:0,
border:false,
items:[
pnProduct,
pnCategory
]
});

},
[
'ProductName',
//'Discontinued',
'QuantityPerUnit',
'UnitPrice',
