How to check for changes in form in Angular 2 using

Question

I have a form with few data fields and two buttons.I want to enable the buttons only if the user makes some changes to the form. I have tried using:

this.for         


        

Answer 1

I guess you can just ignore the first change

this.form.valueChanges
.skip(1)
.subscribe(data => console.log('form changes', data));

Hint: import the skip operator
