Angularjs: Prevent dirty check on mouseenter/mouseleave event

Question

In Angular, is there a way to prevent dirty check on such event?

Actually, my code in these handlers do not change the model so I don't want Angular to perform dirty check on these very often triggered event.

You can keep track of your inputs using Angular FormController ( documentation here ).

You have these properties:

• $pristine - True if user has not interacted with the form yet.
• $dirty - True if user has already interacted with the form.

which means you don't need to worry about mouseenter / mouseleave .

Also, you can find this detailed tutorial on the matter:
