javascript - 在 Backbone 中访问父类

Question

我需要从继承的 MyModel 类中调用父类的 initialize 方法，而不是像我今天所做的那样完全覆盖它。

我该怎么做？

这是我的代码现在的样子:

BaseModel = Backbone.Model.extend({
    initialize: function(attributes, options) {
        // Do parent stuff stuff
    }
});

MyModel = BaseModel.extend({
    initialize: function() {
        // Invoke BaseModel.initialize();
        // Continue doing specific stuff for this child-class.
    },
});

Answer 1

尝试

MyModel = BaseModel.extend({
    initialize: function() {
        BaseModel.prototype.initialize.apply(this, arguments);
        // Continue doing specific stuff for this child-class.
    },
});
