I'm trying to use the onClick function to make a button play an audio file and then disable after a specified length of time (to line up with the end of the audio file). Basically I'm trying to set up a Mission Impossible-esque thing where, when the button is clicked, the audio file plays and at the end of the recording the button disables (the message "self-destructing"). I can get the file to play but I can't figure out how to get the button to disable using the script code. This is what I've got so far. I tried both document.getElementById("briefingButton").this.disabled="true" and document.getElementById("briefingButton").style.display="none" and neither works.

I am working on a react project and i am using Formik for forms. For some reason, the onSubmit method doesnt get triggered. I have been trying to figure out where the error is but i have couldnt.

I have an almost similar setup on another component and that works fine. Any help is appreciated.

There are no issues with validation, because the button becomes enabled only if it satisfies the validation parameters. I click the submit button and nothing happens. I have tried debugging but its not even hitting the onSubmit method.

Below is the implementation.
