Standalone Calendar

Use this if you want a standalone calendar that comes with an input filled and a Today button.

• element: Sets where to insert the calendar to. Can be either a CSS selector string or an HTMLElement object.

• selectedDate: Sets the starting date for the calendar. Can be set to a date string, Date object, or null. If null, todays date will be selected by default. If a string is passed, the format option should also be passed in order for the calendar to know the format of the selectedDate that you are passing.

• format: Use this to specify the input AND output format of the date. Please see the available formats from DayJS.
  Example: 'DD/MM/YYYY'

• iconNext: Sets the next arrow icon. You can pass it either text or an svg.

• iconPrev: Sets the previous arrow icon. You can pass it either text or an svg.

• inputLabel: Sets the label of the date input element.

• inputPlaceholder: Sets the placeholder of the date input element.

• hideInputs: Hides the input and today button from the UI.

• onChange: Use this to provide a callback function that the calendar will call when the date is changed. The callback function will receive a CustomEvent argument that will include the chosen date inside the detail property.

  new datedreamer.calendar({
      ...,
      onChange: (e) => {
          // Get Date object from event
          console.log(e.detail);
      }
  })

• onRender: Use this to provide a callback function that the calendar will call when the calendar is rendered. The callback function will receive a CustomEvent argument that will include a calendar property inside of the event detail property.

      new datedreamer.calendar({
          ...,
          onRender: (e) => {
              // Calendar has rendered
              console.log(e.detail.calendar);
          }
      })

• theme: Sets the style template to use. Options are unstyled and lite-purple.

  • unstyled:

    

  • lite-purple:

    

• darkMode: Enable dark mode styling for the calendar. Works with both unstyled and lite-purple themes.

      new datedreamer.calendar({
          ...,
          darkMode: true
      })

• darkModeAuto: Automatically detect and follow the user's system preference for dark mode. When enabled, the calendar will automatically switch between light and dark mode based on the user's system settings. This takes precedence over the darkMode setting when enabled.

      new datedreamer.calendar({
          ...,
          darkModeAuto: true
      })

  Note: The calendar will listen for system preference changes and update automatically when the user changes their system's dark mode setting.

• styles: Use this property to pass css styles that will be passed into the components style tag.

      new datedreamer.calendar({
          ...,
          styles: `
              button {
                  color: blue
              }
          `
      })

Toggle Calendar

The toggle calendar has the same options as the Standalone Calendar, however the input is a standalone input element which when clicked, triggers the calendar to show.

new datedreamer.calendarToggle({
    ...options
});
