Access "Date Range" selection from the Schedule Board with JavaScript

Hello!

I’ve gotten a requirement and I’m not sure if this is even possible. Basically what I want to do is to be able to store/get the ”Date range” data that the user chooses from the Schedule Board inside a variable in JavaScript OnLoad.

See picture below:

Is there anyway of doing this, like using the ”getElementById” function?

I am aware that Microsoft does not want you to access the DOM. https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/developer/use-javascript?view=op-9-1. But this is the only way where I can see the values, see below.

I’ve researched and so far I haven’t found a solution that is up to date or that is working. Furthermore, I’ve also tried using Xpath without any success.

Thanks for any help!
