p.addTextField("textFieldName", "Label", "")
p.addDatePicker("myDate", "Start date", new Date(), {
"mode": "date"
})
p.addButton("First")
p.addButton("Second")

// if `show` returns false, user hit
// cancel button
if (p.show()) {
let textFieldContents = p.fieldValues["textFieldName"]
let startDate = p.fieldValues["myDate"]

if (p.buttonPressed == "First") {
// do something
}
}
