An Angular Material UI numeric range input form field. It is based on custom form field control and control value accessor which allows inserting range numbers, minimum and maximum.
- Two inputs as one field.
- Auto range validation.
- Supports reactive forms.
npm install ngx-custom-numeric-range-form-field
In component HTML:
<ngx-numeric-range-form-field
[formControl]="rangeControl"
label="Numeric range"
(blurred)="onBlur()"
(enterPressed)="onEnter()"
(numericRangeChanged)="onValueChange($event)"
></ngx-numeric-range-form-field>
In component.ts:
form: FormGroup;
constructor() {
this.form = new FormGroup({
range: new FormControl({
minimum: 10,
maximum: 100,
}, [
Validators.required, //optional
Validators.min(10), //optional
Validators.max(100), //optional
]),
});
}
get rangeControl(): FormControl {
return this.form.get('range') as FormControl;
}
onBlur(): void {
console.log('Value', this.rangeControl.value);
}
onEnter(): void {
console.log('Enter pressed!');
}
onValueChange(value: any): void {
console.log('Changed value: ', value);
}
Customizable input and output decorators:
@Input() label: string; // Label of the control
@Input() appearance: 'legacy' | 'standard' | 'fill' | 'outline' = 'outline';
@Input() floatLabel: 'always' | 'never' | 'auto' = 'always';
@Input() minPlaceholder = 'From'; // Placeholder of the minimum value control
@Input() maxPlaceholder = 'To'; // Placeholder of the maximum value control
@Input() readonly = false; // Indicator wether the both controls are readonly
@Input() minReadonly = false; // Indicator wether the minimum control is readonly
@Input() maxReadonly = false; // Indicator wether the maximum control is readonly
@Input() resettable = true; // Indicator wether the both controls are resettable
@Input() required: boolean; // Required validation
@Input() requiredErrorMessage = 'Field is required!'; // Customizable error message when field is required
@Input() minimumErrorMessage = 'Minimum has been reached!'; // Customizable error message when field has min validation
@Input() maximumErrorMessage = 'Maximum has exceeded!'; // Customizable error message when field has max validation
@Input() invalidRangeErrorMessage = 'Inserted range is not valid!'; // Customizable error message when field has invalid numeric range
@Input() minimumControlName = 'minimum'; // Customizable minimum control name
@Input() maximumControlName = 'maximum'; // Customizable maximum control name
@Input() updateOn: 'change' | 'blur' | 'submit' = 'change'; // The event name for control to update upon
@Input() controlStyle = ''; // Custom control style
@Output() blurred = new EventEmitter<void>(); // Event which emits where user leaves control (focus out)
@Output() enterPressed = new EventEmitter<void>(); // Event which emits when enter is pressed
@Output() numericRangeChanged = new EventEmitter<any>(); // Event which emits when one of range value is changed
