sono | simple yet powerful JavaScript library for working with Web | Audio Utils library

I'm trying to add a validation function in my form, but when I test it I get "Uncaught TypeError: Cannot read property 'handleValidation' of undefined". Since I'm new to reactjs (this is my first webapp made with react) I don't seem to be able to find where the error is. The behavior of this form is: when a user clicks on submit, it first performs the validation, then if valid submit the form via email (to do this I'm using emailjs). Like I said, it fails on the validation step (while everything else works fine, even the email). I hope you can help me, here is my form component:

I would like to use more detailed db for geoparsing.

when I run the script:

I followed the Sonos docs for adding app authentication and the page for using authentication tokens and the result is that the SMAPI server correctly returns an authToken together with a privateKey back to the controller. I can see the authToken being present in the credentials header inside the SOAP messages sent to my SMAPI server.

However, despite the many mentions of this inside the Sonos docs pages related to HTTP requests (I will list the resources links down below), the same authToken is not being sent inside the HTTP header Authorization, this making my CQ server unable to validate requester identity.

I tried the following, without success:

• checking "Requires authorization header" capability in the customsd page of my Sonos device (I tried this because the docs page about capabilities precisely indicates that checking this "Sends OAuth token in the HTTP Authorization header.")

• identifying some correlation between the "X-Sonos-" prefix HTTP headers used when the controller sends SOAP messages to my SMAPI server and the "X-Sonos-" prefix HTTP headers used when the device sends HTTP requests to my CQ server (eventually, I could not find any information that would identify the user based on this)

From Sonos device:

X-Sonos-Playback-Id: RINCON_48??????D201400:3165321802 <= deviceId inserted after RINCON_

X-Sonos-Device-Id: Sonos_U????????????????????????6 <= householdId

X-Sonos-Corr-Id: 267e3e0c-75ca-4b9d-8be4-b8a795a462a3 <= unique each time

From macOS Controller:

X-Sonos-Controller-ID: 68:??:??:??:??:07 <= the same each time

X-Sonos-Api-Key: 8??????e-7??7-4??f-b??6-7??????????0 <= the same each time

X-Sonos-Corr-Id: 648ec896-e043-44f8-bfba-cd0a80c9d857 <= unique each time

• checking both "Include SMAPI context headers with all requests" and "Include Zone Player IDs in credentials header" capabilities in the customsd page of my Sonos device (I tried this following the answer to this sonos tagged stackoverflow question Now that device ID is deprecated, is there another way to identify the client?)

The docs links I mentioned above that refer the presence of the auth token inside the HTTP Authorization header are the following:

• the GET /context CQ API method page says to return 401 Unauthorized when "The access token has expired or is invalid."

• the GET /itemWindows CQ API method page says "the player can use this API to obtain a new access token in the response from your cloud queue server" and "The request contains the access token in the authorization header" and "If the access token is set to expire soon, an updated one is included in the X-Updated-Authorization header of the response"

• the POST /timePlayed CQ API method page says "The request header contains the access token in the authorization header" and that the method returns ERROR_SONOS_TOKEN_EXPIRED when "SMAPI OAuth token is expired, and user must re-authorize the account"

• the GET /version CQ API method page says again that "The request contains the access token in the authorization header" and talks about a now deprecated updateToken parameter and also says that "If the access token is set to expire soon, you should include an updated token in the X-Updated-Authorization header."

But the most clear mention is in the page about HTTP requests, because it's not particular just for the CQ API endpoints but for all HTTP endpoints, even those hosted by the SMAPI server itself. The page reads the following 2 excerpts:

and

To conclude, with so many mentions of it in the official Sonos docs, why isn't this essential header being transmitted in the HTTP Authorization header? And how should a CQ verify the identity of the requester without the presence of this authToken on each API method request?

i must validate a form before submit, in this code I use routes, so i can't use $_SERVER["PHP_SELF"] (maybe) someone can help me please?

I need to calculate and get inventory available date for each Sales Order(SO). Each SO fulfillment is based on first-in-first-fulfill. Fulfillment is based on currently available inventory with purchase (PO) quantity and PO arrival date. For example:

Current inventory quantity: 100 ea

PO quantity and available date is:

I have this part of code that work but strangely the latest step of outputting the result doesn't work.. When i try to log the first element of array it returns undefined bacause the execution is asynchronous. I thought to build a series of nested callbacks but I think that is a bad practice. Is there any other way to makes it work without create nested promise callbacks?

CODE:

I know there are a lot of question similar but none have helped me so I'm here. I have a 9 button grid, if i click one it change color (orange) but if i click another one they both stay orange. i don't want it. i want that if a button is already orange, the new one get colored but the first one return to normal color. I tried in a lot of ways but i'm not so good at js and HTML so i'm not understanding where the problem is

I'd like to have the 9 button (3x3) to get a color change after getting clicked, so i used a .btn:focus class where I set a bg-color and a text color. the problem is the fact that if I click somewhere else (in the blank spot of the page or in the radio type input below) this color change disappears, but I need it to be there. It should disappear only if I click a different button of the same group of 9 but I don't know how to do it.

I tried with a JS function in the lower part of the HTML code that should add to my 9 buttons a class that should color them but that doesn't work. (I've just realised that even if this last JS function would work, my problem would be the fact that if I click a button that is not the one already selected I'd have 2 different button colored. I don't know how to solve my problem.)

What is causing my program to fail while loading files? I'm posting the two function involved.

I'm using the libcomdlg32.a library to get the path using a user-friendly interface.
