Transform value from input to model using Pipe

Question

For instance, let's consider the following scenario:

• Angular 5.2
• there is a two way binding using (ngModel) between model and input field in the view.
• there is a Pipe used to show model's milliseconds value as seconds in the input field.
• The user then want to type the value in seconds

Can I have a Pipe ( or something similar ) that transforms back the seconds into milliseconds ? A Pipe or something similar meaning NOT writing manually " on value change " handler methods in the component for each inputs

Answer 1

Short answer, no.

If you want to convert your milliseconds to seconds from the model to the input, then yes, you can use a pipe. But if the user can change it, you will have to let go of the pipe, since pipes are used just to display values, and not to edit them.
