Close popup automatically and cancelling barcode scanner

[Angela Rogers]

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?

[Angela Rogers]

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?

[Angela Rogers]

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.
