DatePicker Usage

Basic Usage

// app.module.ts
import { QeydarDatepickerModule } from '@qeydar/datepicker';

@NgModule({
  imports: [QeydarDatepickerModule]
})
export class AppModule { }

// component.ts
@Component({
  template: `
    <qeydar-date-picker 
      [(ngModel)]="selectedDate"
      [calendarType]="'jalali'"
    ></qeydar-date-picker>
  `
})
export class AppComponent {
  selectedDate: Date | string = '1403/01/01'; // Can accept both Date object and string
}

Range Selection

The DatePicker supports flexible range selection with multiple ways to handle values:

@Component({
  template: `
    <qeydar-date-picker
      [(ngModel)]="dateRange"
      [isRange]="true"
      [rangeInputLabels]="{ start: 'From', end: 'To' }"
      [emitInDateFormat]="false"
      [calendarType]="'jalali'"
    ></qeydar-date-picker>
  `
})
export class AppComponent {
  // Using string values
  dateRange = {
    start: '1403/08/12',
    end: '1403/08/15'
  };

  // Using mixed values (string and Date)
  dateRange2 = {
    start: '1403/08/12',
    end: new Date()
  };

  // Using Date objects
  dateRange3 = {
    start: new Date('2024-01-01'),
    end: new Date('2024-01-07')
  };

  // With emitInDateFormat=true, values will be emitted as Date objects
  onRangeChange(range: { start: Date, end: Date }) {
    console.log('Start:', range.start);
    console.log('End:', range.end);
  }
}

Range Selection with Predefined Periods

// Define custom period labels
const customLabels: CustomLabels[] = [
  {
    label: 'This Week',
    value: [new Date('2024-01-01'), new Date('2024-01-07')]
  },
  {
    label: 'Last 7 Days',
    value: ['1403/08/05', '1403/08/12'] // Can use strings for Jalali dates
  },
  {
    label: 'Custom Range',
    value: 'custom'
  }
];

@Component({
  template: `
    <qeydar-date-picker
      [(ngModel)]="dateRange"
      [isRange]="true"
      [customLabels]="customLabels"
      (onChangeValue)="onRangeChange($event)"
    ></qeydar-date-picker>
  `
})

Date and Time Selection

@Component({
  template: `
    <qeydar-date-picker 
      [(ngModel)]="selectedDateTime"
      [format]="'yyyy/MM/dd HH:mm:ss'"
      [showTimePicker]="true"
      [timeDisplayFormat]="'HH:mm'"
      [showToday]="true"
    ></qeydar-date-picker>
  `
})
export class AppComponent {
  selectedDateTime: Date | string = new Date();
}

Value Format Options

@Component({
  template: `
    <qeydar-date-picker
      [(ngModel)]="selectedDate"
      [valueFormat]="'gregorian'"  // 'gregorian' | 'jalali' | 'date'
      [calendarType]="'jalali'"
    ></qeydar-date-picker>
  `
})

TimePicker Usage

The TimePicker is a separate component for time selection:

@Component({
  template: `
    <qeydar-time-picker
      [(ngModel)]="selectedTime"
      [timeFormat]="'24'"
      [showSeconds]="true"
      [minTime]="'09:00'"
      [maxTime]="'17:00'"
    ></qeydar-time-picker>
  `
})
export class AppComponent {
  selectedTime = '14:30:00';

  // Or using Date object with valueType="date"
  selectedDateTime = new Date();
}

TimePicker with Custom Format

<qeydar-time-picker
  [(ngModel)]="time"
  [timeFormat]="'12'"
  [displayFormat]="'hh:mm a'"
  [rtl]="true"
  (timeChange)="onTimeChange($event)"
></qeydar-time-picker>

Inline Mode with Date Adapter

@Component({
  template: `
    <qeydar-time-picker
      [(ngModel)]="time"
      [inline]="true"
      [dateAdapter]="dateAdapter"
      [timeDisplayFormat]="'HH:mm:ss'"
      (timeChange)="onTimeChange($event)"
    ></qeydar-time-picker>
  `,
})
export class AppComponent {
  constructor(public dateAdapter: GregorianDateAdapter) {}
}

Form Integration Examples

Reactive Forms with Both Components

@Component({
  template: `
    <form [formGroup]="form">
      <!-- Date Range -->
      <qeydar-date-picker
        formControlName="dateRange"
        [isRange]="true"
        [calendarType]="'jalali'"
      ></qeydar-date-picker>

      <!-- Time -->
      <qeydar-time-picker
        formControlName="time"
        [timeFormat]="'24'"
      ></qeydar-time-picker>
    </form>
  `
})
export class AppComponent {
  form = this.fb.group({
    dateRange: [{
      start: '1403/08/12',
      end: new Date()
    }],
    time: ['14:30']

    name="dateRange"
    [isRange]="true"
    required
  ></qeydar-date-picker>

  <qeydar-time-picker
    [(ngModel)]="time"
    name="time"
    required
  ></qeydar-time-picker>
</form>
