ngx-barcodeput
Demo
Formerly called ngx-barcodeput
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
(onDetected)="onDetected($event)">
Installation
npm install --save ngx-barcodeput
Usage
Add NgxBarCodePutModule
to your list of module imports:
import { NgxBarCodePutModule } from 'ngx-barcodeput';
@NgModule({
declarations: [AppComponent],
imports: [BrowserModule, FormsModule, NgxBarCodePutModule],
bootstrap: [AppComponent]
})
class AppModule {}
You can then use the directive in your templates:
@Component({
selector: 'app',
template: `
<input type="text"
ngxBarCodePut
maxlength="14"
[debounce]="300"
autocomplete="off"
[skipStartLength]="5"
(onDetected)="onDetected($event)"
(onBackspace)="onBackspace($event)">
`
})
export class AppComponent {
public onDetected(event: IDetect) {
console.log(event.type, event.time, event.value);
}
public onBackspace(event: IBackspace) {
console.log(event.code, event.keyName, event.value);
}
}
