Ember.js如何從子類調用超類或基類方法？

Question

當過我嘗試從子類ember.js調用基類的方法，我得到以下錯誤

斷言失敗：Ember.Object.create不再支持調用定義方法_Super

App.BaseClass = Ember.Object.extend({ 
sayHello: function(){ 
    //my code 
} 
}); 

App.SubClass = App.BaseClass.extend({ 
//some code here 

sayHellow: function(){ 
//some code of subclass 
. 
. 
. 
this_super(); // This causes error: Assertion failed: Ember.Object.create no //longer supports defining methods that call _super 
} 
}); 

Answer 1

你應該使用this._super（）

sayHello: function(){ 

//some code of subclass 

. 

. 

. 

this._super(); 

// This causes error: Assertion failed: Ember.Object.create no //longer supports defining methods that call _super 

} 

});
