Identify the attribute change event in KnockoutJS?

问题:

Is there any way to Identify the attribute change event in KnockoutJS?? I found solutions in jQuery: firing event on DOM attribute change firing event on DOM attribute change

But It would be good If I can do it with KO.

Thanks.

If the attribute change is bound to a property in your view model, then you can simply subscribe to that property to get notified of changes.

myViewModel.myProperty.subscribe(function(newValue) {
    alert("This property changed!!");
});
