Overriding fetch() method in backbone model
提问by Drejc
I would like to override the default fetch() method in a Backbone model, thus calling it only when needed.
我想覆盖 Backbone 模型中的默认 fetch() 方法，从而仅在需要时调用它。
Something like this:
像这样的东西：
Account.Check = Backbone.Model.extend({
model : Account.Item,
url : Settings.Url.checkAccount,
fetch : function(options) {
if (someCondition()) {
// do some stuff
} else {
super.fetch(options);
}
}
});
My question is how to provide the same behaviour as the default fetch() method in the // do some other stuffpart?
我的问题是如何在// do some other stuff部分提供与默认 fetch() 方法相同的行为？
回答by alex
This should do it...
这个应该可以...
fetch : function(options) {
if (someCondition()) {
// do some stuff
} else {
this.constructor.__super__.fetch.apply(this, arguments);
// Or (less flexible)
Backbone.Model.prototype.fetch.apply(this, arguments);
}
}
