Ember计算属性_super

Question

我想知道是否有办法获得_super计算属性？

例如:

controllers/core-controller.js

export default Controller.extend({
    myAttribute: computed(function() {
        return {
            bar: this.get('bar')
        };
    });
});

controllers/my-controller.js

import CoreController from 'controllers/core-controller';

export default CoreController.extend({
    myAttribute: computed(function() {
        let super = this.get('_super') //I'm trying to get the myAttribute object from the CoreController
        return merge(super, { foo: 'foo' });
    });
});

最好的方法是什么？

谢谢.

你可以致电this._super(...arguments):

import CoreController from 'controllers/core-controller';

export default CoreController.extend({
    myAttribute: computed(function() {
        let superValue = this._super(...arguments);
        return merge(superValue, { foo: 'foo' });
    });
});
