๐ Avoid losing form data
Challenge #48
Context
As a member of the development team, you need to address a specific request from the product owner, ๐งโโ๏ธ Bob. He wants to develop a new feature in response to customer complaints about losing form input information.
User Story
Hereโs the feature expressed as a user story with a functional expectation:
As a user, I would like to have an alert dialog box that appears when I attempt to navigate away from the page, after I have started entering information into the form.
Acceptance Criteria
- If one of the form fields is not empty and the user tries to navigate to a different route or page, or wants to reload the page, show an alert dialog to avoid losing form data.
- The content of
dialog.component.ts
must be used for your alert. - The appearance and behavior of the alert dialog box must comply with W3C conventions, see alert dialog pattern.
- Maximize the use of the new concepts and syntax in the latest version of Angular.
Tips ๐คซ (if you really need it and after careful consideration)
- Use the Material CDK Dialog or Overlay - don't forget to add
@import '@angular/cdk/overlay-prebuilt.css'
instyles.scss
- Use the CanDeactivate guard in the new functional approach.
