example

Constructing a custom dialog instance

let d = new Dialog({
 title: "Test Dialog",
 content: "<p>You must choose either Option 1, or Option 2</p>",
 buttons: {
  one: {
   icon: '<i class="fas fa-check"></i>',
   label: "Option One",
   callback: () => console.log("Chose One")
  },
  two: {
   icon: '<i class="fas fa-times"></i>',

   callback: () => console.log("Chose Two")
  }
 },
 default: "two",

Static defaultOptions

Methods

getData

  • getData(options?: {}): { content: any; buttons: {} }
