检测observableArray中是否发生更改 [英] Detect if a change occur in observableArray

问题描述

有人知道吗，如果使用ko映射时是否可以检测到observableArray内部何时发生变化，这意味着不必手动创建模型?

Does anyone have idea, if it's possible to detect whenever a change occur inside observableArray while using ko mapping, this mean without having to create the model by hand?

self.items = ko.observableArray([])
var data = ko.mapping.fromJS(result)
self.items.push(data);

我想记录对象数组内任何属性中发生的任何更改.

I would like to log any changes occurred in any property inside my array of objects.

谢谢

推荐答案

如果我没记错的话，您应该可以在可观察对象上使用subscribe来获取该信息.

If I'm not mistaken, you should be able to use subscribe on the observable to get that information.
