Angular directive for handling input events. Useful for determine input using a barcode-scanner.
Like binding to a regular type
event in a template, you can do something like this:
<input ngxBarCodePut
(detected)="onDetected($event)">
npm install --save ngx-scan-detect
You can then use the directive in your templates:
@Component({
selector: 'app-ngx-scan-detect',
templateUrl: './ngx-scan-detect.component.html',
styleUrls: ['./ngx-scan-detect.component.scss'],
standalone: true,
imports: [CommonModule, NgxBarCodePutDirective],
})
export class AppComponent {
public onDetected(event: IDetect) {
console.info(event);
/* {event: KeyboardEvent, value: "sezmars", time: 0.07083499999716878, type: "scanner"} */
/* {event: KeyboardEvent, value: "3333333", time: 0.17083499999716878, type: "keyboard"} */
}
public onDelete(event: IDelete) {
console.info(event);
/* {event: KeyboardEvent, value: "3333333", type: "delete"} */
}
}
