apex-qr-code-scanner's Issues

Can't scan multiple code ?

Hi,

Thank you for your awesome plugin.

I'm trying to scan several codes , but the plugin scans only the first one. The other ones are detected in the video streaming but the scan trigger is not working.

After each scan I'm running the following commands :

alert(scannedValue); $("#scannerregion").trigger("scannerPause"); $("#scannerregion").trigger("scannerPlay"); $("#scannerregion").trigger("resetValue");

This code shows the scanned value only once. No JS error is raised.

Am I missing something please ?

thanks.
Cheerss,

Android Chrome - Uncaught (in promise) DOMException: Could not start video source

Again thank you so much for such a wonderful plugin. It works flawlessly on my desktop. I am however having an issue on mobile. The camera does not appear to start up. It simple spins the loading.

I was able to perform remote debugging and the error message in the remote chrome console reads:

Uncaught (in promise) DOMException: Could not start video source

Environment details
APEX-QR_Code-Scanner version: 1.5.1.0
Galaxy Note10+ 5G
Android 10 base
Android chrome browser: 89.0.4389.105

I have tested this on multiple APEX apps and your example site below and all give the same error.

Any help would be greatly appreciated!

Long number strange behavior

Amazing plugin thank you! I am experiencing strange behavior with longer numbers in sequential order I was hoping you could suggest a fix for?

When I scan the following QR codes in order everything works fine:
QR 1 - 542099931871011
QR 2 - 54209993187108
QR 3 - 542099931871010

Everything works as expected but when I scan QR 1 then QR 3 the page item does not update.
I suspect this could be a truncating issue because the QR 1 and QR 3 are in sequential order?

I am currently playing around with number conversation and triggering a value reset after every scan as work around but wondering if there is a more permanent solution?

Thank you again for your amazing contributions.

Read the same QRCode more than once

Hi !

First of all, I would like to say that your plugin is very good! You did a great job and I believe it will help a lot of people, especially the APEX community. 😄

Now, I need your help with my situation. I configured the plugin in my app and it is running 100%! But it has a behavior that I need to change.

When I read a QRCode the plugin returns its code and I can handle the code read in my app, however, it is not possible to re-read the same code ... How can I do this?

I need to be able to read the same code more than once, can you help me or tell me what I need to do for this?

Problem with scanning similar QR codes

I try to scan few QR Code one after another.
It works when the QR Code are completely different, but when i try to scan similar QR Code the APEX item connected with plugin no change.
The same when I use "Execute JavaScript" mode with "alert". There is no effect when QR codes are simmilar.

My similar QR codes lead to URL:

http://localhost/ords11/f?p=TEST:GET:::::ITEM:12345
http://localhost/ords11/f?p=TEST:GET:::::ITEM:12346

Library recognise both codes but only when I refresh page.
Have you any idea what is the problem?

QR code works well when I use library sample page: https://cozmo.github.io/jsQR/

QR Scanner stops scanning on Iphone (Safari/Chrome)

Hi Ronny,
Thanks for the plugin. We're using it to scan QR codes on mobile phones and this works great on Android.
We have one issue however: after some scans on an Iphone (6-10 scans often) it stops recognizing QR codes.

The situation:

1. QR scanner plugin sets an item when a QR code is scanned.
2. On change of this item, a message is shown and after some delay (setTimeout), $("#qr_scanner").trigger("resetValue"); is called.
3. Scanning the same code or a different one goes well for about 6-10 tries
4. The camera is still working but no red border appears around QR codes anymore. It doesn't seem to recognize any QR codes at this point.

Any idea what we can do about this?

Thanks!

The camera has extended beyond its designated region and is consistently using the wide-angle mode

I'm using version 22.12.15, and when I open the web on both my PC and mobile devices, I'm encountering a problem where the camera image spills outside the designated region, and the camera always stays in wide-angle mode. The aspect ratio of 1.4 is not causing overflow, but the camera remains in wide-angle mode. How can I fix the camera image to fit within the region and be able to set the camera zoom? I'm using an iPhone 14 and a Samsung 22

IOS can't run the camera to scan the QR_Code

This APEX-Plug you developed is so nice . I find that it works well in Android but in IOS by Wechat

Apex 22.2.0

Hello, I am new working with Apex, I have tried without success to implement barcode scanning with Apex, using the Plug-In for the region, however it has not been possible to open the camera on IOS or Android. I don't know if the problem is the version of Apex that I'm using (22.2.0) or I did something wrong in the installation process of the Plug-In for the region (I don't think so), if I have misconfigured the region or the execution of the buttons. I think I'm doing everything according to your instructions, but it's not working. I would appreciate your help and guidance. Thanks in advance
