描述

[x] Feature request

It would be nice to add support for multiple updateOn: events. e.g updateOn: "blur submit".

There is scenario where single "blur" is not enough.

For example:

  1. we have simple form with 2 fields and one submit button
  2. user enters value for the first field and navigates to the second one
  3. user enters value for the second field and submit form by pressing enter key

In my example, the form will be submitted with empty value in the second filed.

研究方向
Investigate how updateOn is currently implemented in Angular forms, likely in the ReactiveFormsModule or TemplateDrivenFormsModule. Review the existing issue comments for community input on desired behavior. Design a solution to accept multiple events (e.g., 'blur submit') and update the AbstractControl class to handle combined events. Consider backward compatibility with the current one event string.
