Hey there!
When you’re creating the field, try using these settings (and update the date formats to your linking):
const field = new Annotations.Forms.Field(
'DatePicker',
{
type: 'Tx',
value: '1.1.2004',
// Actions need to be added for DatePickerWidgetAnnotation to recognize this field.
actions: {
F: [
{
name: 'JavaScript',
// You can customize the date format here between the two double-quotation marks
// or leave this blank to use the default format
javascript: 'AFDate_KeystrokeEx("mmm d, yyyy");',
},
],
K: [
{
name: 'JavaScript',
// You can customize the date format here between the two double-quotation marks
// or leave this blank to use the default format
javascript: 'AFDate_KeystrokeEx("mmm d, yyyy");',
},
],
},
},
);
Let me know if this doesn’t work for you.
