The confirm() method displays a pre-configured modal dialog with custom HTML content and OK and Cancel buttons.
DayPilot.Modal.confirm(message[, options])message (string) - HTML message
options (object) - an object that specifies custom DayPilot.Modal properties
Returns a Promise. The promise resolves when the modal dialog is closed using either button or by clicking the background, and it receives the args object from DayPilot.Modal.onClosed. The promise never rejects.
In addition to the standard DayPilot.Modal properties, the options object can define custom button text using options.okText and options.cancelText.
By default, the pre-configured dialog uses DayPilot.Modal.height = 40 and DayPilot.Modal.useIframe = false.
const modal = await DayPilot.Modal.confirm("Delete this item?", {
okText: "Delete",
cancelText: "Keep"
});
console.log("Dialog closed", modal.result);JavaScript confirm() Replacement [code.daypilot.org]
