Docs

Layout

• Show/hide the topstrip, defaults to true. If false will also hide the navigationbuttons in this strip.

<mg-calendar [show_topstrip]="true|false"></mg-calendar>

• Show/hide the 2 navigationbuttons at the top, defaults to true.

<mg-calendar [show_navigator]="true|false"></mg-calendar>

Colors

• Color for topstrip, defaults to transparent.

<mg-calendar color_topstrip="red|#FF0000|.."></mg-calendar>

• Color for the strip displaying the days of a week, defaults to transparent.

<mg-calendar color_weekstrip="green|#00FF00|.."></mg-calendar>

• Color for the view containing the days of a month, defaults to transparent.

<mg-calendar color_monthview="blue|#0000FF|.."></mg-calendar>

Templating

Days of year

You can template the way content looks, just pass the template with its content. You can get information about a day using the moment object returned. moment is a Moment-object from the MomentJS-library. The state of a day (isselected, ismultiselected, istoday, ispast) are returned as a string of the states seperated by a space.

• Change the apearance/content of a displayed day in the month, defaults to a default style.

Component.html

<mg-calendar [template_monthcurrent]="currentdaystyle"></mg-calendar>

<ng-template let-day="moment" let-daystates="states" #currentdaystyle>
  <!-- states printed as classes: class="isselected .."-->  
  <div class="{{ states }}">
      <p>
          {{ getMonth(day) }}
      </p>
      <p>
          {{ getDate(day) }}
      </p>
    </div>
</ng-template>

Where getMonth() and getDate() are own functions:

Component.ts

getMonth(moment: moment.Moment) : string {
  return moment.clone().format('MMMM');
}

getDate(moment: moment.Moment) {
  return moment.clone().date();
}

This approach can also be used when templating the days for next month and the previous month:

<mg-calendar [template_monthnext]="nextdaystyle" [template_monthprev]="prevdaystyle"></mg-calendar>

Topstrip

Template the top strip, this section is divided into 2 parts: the title and the navigation. Template can access year and month vars of the current view. month is a number from 0 - 11, year represents the year of the displayed view.

Component.html

<mg-calendar [template_title]="titlestyle"></mg-calendar>

<ng-template let-year="year" let-month="month" #titlestyle>
    <p>
        {{ year }} {{ getMonth(month) }}
    </p>
</ng-template>

Component.ts

getMonth(month : number) : string {
  return moment().clone().month(month).format('MMMM');
}

Handlers

onSelectionChanged()

Triggered when a new selection of days has made on the calendar. It returns an array of Moment-objects of the new selection.

Component.html

<mg-calendar (onSelectionChanged)="onSelectionChanged($event)"></mg-calendar>

Component.ts

onSelectionChanged(event: any[]) {
  console.log(event.length);
}

onNavigated()

Triggered when a navigation in month occured, returns a month and year navigated to.

Component.html

<mg-calendar (onNavigated)="onNavigated($event)"></mg-calendar>

Component.ts

onNavigated(event: any) {
  console.log(event.month);
}
