Ember.js如何从子类调用超类或基类方法？

Question

当过我尝试从子类ember.js调用基类的方法，我得到以下错误

断言失败：Ember.Object.create不再支持调用定义方法_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

你应该使用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 

} 

});
