Declaration
@MainActor mutating func willSubmit(formInfo: WebPage.FormInfo) asyncParameters
- formInfo:
The form values that will be submitted for this navigation
Discussion
This is an informative callback only. The form values cannot be changed, nor can the navigation be changed to not submit a form.
The form submission will not actually proceed until after this callback asynchronously resolves.
