This hook is triggered after the main object field value changes on the form and before UI events/calculations are executed. It allows extra business actions after editing main-object fields, including but not limited to the following capabilities:

Using this hook for data updates is not recommended. Prefer the form.change.end hook instead.

• Listen for main object field value changes
• Modify main object data

Parameters

Parameter	Description	Type
Common parameters	See details	--
changeData	New data after the change	Object
oldData	Previous data before the change	Object

Return Value

None

Basic Example

Change other field values after the main field value changes

export default class Plugin {
    apply() {
        return [{
            event: 'form.dataChange.after',
            functional: this.formDataChange.bind(this)
        }]
    }
  	formDataChange(context, plugin) {
      if(context.changeData.name) { // detect that the main property field has changed
         context.dataUpdater.updateMaster({
          owner: ['1000']
         });
       }
    }
}

Notes

1. Field values changed in this hook will also participate in subsequent calculation/UI-event logic

After data is modified in this hook, subsequent calculations and UI events will be processed based on the updated values.
