Struct FieldActions

Available on crate feature javascript only.

The ten /AA entries a field can carry, as their JavaScript source.

None is the ordinary case and is not an absence to be filled in later: nearly every field in nearly every document has no script at all, and a hook with no script takes the permissive answer — which is NoScripts’s answer, and is correct rather than a fallback.

Four value hooks and six event ones

The first four intervene in a value: they can rewrite what is typed, refuse a commit, compute another field or produce a display string. The six below them intervene in nothing — a pointer or focus script can talk to the host and read the form, and event.value throws for it — which is why they are fired rather than consulted.
