barcode | computer list , check the computers and in massive action | Barcode Processing library

I have a table:

What i want to achieve looks like this:

I have looked through mulitple sources online and on stackoverflow and many show that we can display the value in a textfield by using a raisedbutton.

So far i managed to use the barcode scanner to scan but the scanned barcode doesnt appear in the textfield like i want it to.

My Code:

I'm working on a feature where client get's discount when buying a package.

The item on the left is fixed and doesn't change. It comes in package with the item on the right where client can choose a snowboard:

All I need is that when client chooses a size, but then swipes to the next snowboard the size chosen from the previous snowboard would be set back to default 'CHOOSE SIZE OPTION'.

Here is the code of the Parent Component:

I am trying to make an inventory management app and I created a schema for mongoDB through mongoose that looks like this

I've created a multi-sheet workbook that has Manifest Data (Sheet1), Sammy (Sheet2), Trev (sheet3), Scan Data In (Sheet4). On each of the worksheets is a column labeled Connote and the data within cells of the column relates to a barcode on the paperwork we use. When I open a drivers worksheet i will scan the barcode from the paperwork and information will be pulled from the Manifest Sheet as well Time/Date Stamping using VBA. But what I'm trying to do is pull the drivers name which is in a cell on their worksheet back to the Manifest Data sheet which relates to the connote they have just scanned. I'm happy to upload the working sheet if required. Manifest Data Sheet Drivers Sheet https://1drv.ms/x/s!AiXQNwMzQ3OrnCxn4D54gpnBH9V0?e=fxsTnz

I'm trying to write some vanilla javascript code to do barcode scanning from my website, however I can't even get past the first step using the Quagga javascript library. My code is currently this:

I have a file name: PPETRD424_279121_2.pdf that I would like to extract only the 279121 and use it to insert a barcode into the file itself. I need to do this to multiple files but each number is different. Every number is separated by the underscores. Im not sure where to start.

I have a table layout that gets dynamically filled with data the table contains 4 columns, 3 are text views and 1 is and image button

Im pretty much using the Nintendo Switch Joy-Con controllers demo which I've modified a little to make it work with my barcode scanner. And it just wont work and if it does work it works once in 100 site refreshes.
