This video introduces the concept of client-side scripting in model-driven Power App forms using JavaScript. Developers can leverage the capabilities on offer here to put in place robust validation, presentation or automation behaviour to suit any scenario, and we’ll see how we can deploy a basic form function out and debug it using browser-based tools.
This video is part of my series focused on providing small, bite-size learning tools to prepare to sit Microsoft Exam PL-400: Microsoft Power Platform Developer. More details about the exam can be viewed below:

Thanks for the video, could you please go into more detail on how to add JavaScript to a specific field on the form to get it to update live? E.g. having a number/currency field sum up columns on a subgrid as they are added, similarly to a rollup but live

Hi Harry, based on your example, the broad steps I would follow to implement this would be as follows: - Create a JavaScript function that returns all rows from the grid (docs.microsoft.com/en-us/powerapps/developer/model-driven-apps/clientapi/reference/grids/grid/getrows?WT.mc_id=BA-MVP-5003861), iterates through the result sets and then updates the field on the parent row (docs.microsoft.com/en-us/powerapps/developer/model-driven-apps/clientapi/reference/attributes/setvalue?WT.mc_id=BA-MVP-5003861) - Attach the JavaScript to the parent form and trigger the function to run as part of the subgrids OnSave event (docs.microsoft.com/en-us/powerapps/developer/model-driven-apps/clientapi/reference/events/grid-onsave?WT.mc_id=BA-MVP-5003861) Hope this helps!

Hi Joe, loving the PL-400 videos. How much actual Java Script does one need to know for the PL-400 exam?

I would say you need to have foundational understanding of how the language works, but for PL-400, the focus is more on understanding what is possible via JavaScript and how to work with the various methods exposed out by the platform.
