I am using this javascript: setTimeout("Appery.navigateTo('ScanScreen',{})" , 2000); within an error popup to automatically go back to a page (ScanScreen) that runs the barcode scanning service on Load. However, if I click cancel on the scanning, it keeps popping up this error popup, closes, I hit cancel, and it pops up again, so I can never get out of the scanning. Is there a better way to close a popup automatically after 2 seconds? Is there a way to control what the cancel button on the barcode scanner does?

Hello,

Please clarify what event do you use to invoke your JavaScript?

The page "ScanScreen" has a Load event that invokes the barcodescanner service. On success, the barcodescanner invokes a rest service that updates a database. On fail, it loads the error popup. So, I guess clicking cancel on the barcode scanning windows sends a fail instead of just closing. I guess I'll have to change how I have this working.

Hi Angela,

Can you post code you using to make transition to specific page?

I resolved the issue by mapping the 'cancelled' response from the barcodeservice to a local storage variable, then used the following javascript:

if (localStorage.getItem('scancancelled')=="true"){
Appery.navigateTo('startScreen');
}
else {
myrestservice.execute({});
}

Apparently when you click "Cancel" on the barcode scanning it still fires the Success event. This code did the trick for me. Maybe it will help someone else.

Hi Angela,

Thank you for sharing this!
