How to pass array dynamically to a variable in angular

Question

https://github.com/hsuanxyz/ion2-calendar/issues/241

Here it is written as

you can change the default date color by pushing the days to daysConfig and passing dayConfig: { marked: true} and then you can change the color with .marked class css and also you can pass with the 'cssClass' key

daysConfig.push({
date: new Date(item),
marked: true
});

DayConfig {
date: Date;
marked?: boolean;
disable?: boolean;
title?: string;
subTitle?: string;
cssClass?: string;
}

here's the interface of daysConfig

When i tried like this

 options: CalendarComponentOptions = {
    from: new Date(2000, 0, 1),
    pickMode: 'multi',

    daysConfig: [
      {
        date:new Date(this.absentdate[0]),
        marked:true,
        cssClass: 'my-cal'
      },
      {
        date:new Date(this.absentdate[1]),
        cssClass:'my-cal',
       marked:true
      },
      {
        date:new Date(this.absentdate[2]),
       cssClass:'my-cal',
        marked:true
      }
    ],

  };

it worked

But i have an array of absent_date as

 absentdate :string[]=['2020-01-03', '2020-01-04', '2020-01-28'];

which keeps on varying according to the month.How can i change the hardcoded value to the absent dates that i have given in the array.Please help me.

T Template ::

<ion-calendar [(ngModel)]="date"
                  (change)="onChange($event)"
                  [options]="options"
                  type="string"
                  format="YYYY-MM-DD"
                  readonly="true"

                  >
    </ion-calendar>

Initialize the following format for options

options: CalendarComponentOptions = {
    from: new Date(2000, 0, 1),
    pickMode: 'multi',
    daysConfig: []
};

Next, you can loop through the absentdate[] and push each data set into the options as shown below.

absentdate.forEach(element => {
    var data = {
        date:new Date(element), //can give custom data
        marked:true, //can give custom data
        cssClass: 'my-cal' //can give custom data
    }
    options.daysConfig.push(data)
})

Note: This might sort the data sometimes. if you do not want the sort, you can use the below line instead of push. It will insert the data at the end of the array every iteration

options.daysConfig.splice(options.daysConfig.length, 0, data)

This should provide following output. Let me know if this was what you were looking for :)

{ from: 1999-12-31T18:30:00.000Z,
  pickMode: 'multi',
  daysConfig:[ 
      { 
          date: 2020-01-03T00:00:00.000Z,
          marked: true,
          cssClass: 'my-cal' 
      },
      { 
          date: 2020-01-04T00:00:00.000Z,
          marked: true,
          cssClass: 'my-cal' 
      },
      { 
          date: 2020-01-28T00:00:00.000Z,
          marked: true,
          cssClass: 'my-cal' 
      } 
  ] 
}
