Scanner detection event not firing
I have tried the plugin according to the documentation but the event is not firing.
Here's the reproduction link
Cannot set barcodeType or Max Length
Hello Everybody... I am trying to integrate the barcode scanner but somehow it is stuck with 'ean12' type. I have tried to do everything I could understand but no luck. I will describe the issue below and what I have tried and let me know what I am missing.
Modal which is having the scanning component
<div class="modal-body">
<ngx-sw-scanner-detection
(scan)="barcodeScanned($event)"
[config]="{scannerEndsWith: 'Enter'}"
>
</ngx-sw-scanner-detection>
<!-- <input type="text" #barcode ngbAutofocus (keydown)="barcodeScanned($event)"> -->
<img src="assets/media/modals/scanner.png" class="img-fluid mx-auto d-block" />
</div>
This configuration results in the following response in my handler:
barcode: "295642975221"
length: 12
valid: false
__proto__: Object
If I change the configuration to:
<div class="modal-body">
<ngx-sw-scanner-detection
(scan)="barcodeScanned($event)"
[config]="{scannerEndsWith: 'Enter', barcodeType: 'ean14', maxLength: 14}"
>
</ngx-sw-scanner-detection>
<!-- <input type="text" #barcode ngbAutofocus (keydown)="barcodeScanned($event)"> -->
<img src="assets/media/modals/scanner.png" class="img-fluid mx-auto d-block" />
</div>
Nothing happens....
I even went and hardcoded the type in the library's config model instead of 'ean13' but still it doesn't pick 14 characters. It will always pick 12 characters.
Please let me know what wrong I am doing. I am badly stuck right now. Thank you.
