All the client scripting concepts and APIs explained in this documentation also apply to Dynamics 365 Customer Engagement (on-premises) users.
However, if your business requirement can't be achieved using a business rule, you will find that client-scripting using the client API object model provides a powerful way to extend the behavior of the application and enable automation in the client.
Use client scripting in model-driven apps
Forms in model-driven apps help display data to the user. A form in model-driven apps can contain items such as columns, a quick form, or a grid. An event occurs in model-driven apps forms whenever:
- A form loads.
- Data is changed in a column or an item within the form.
- Data is saved in a form.
Model-driven apps provides you a rich set of client APIs to interact with form objects and events to control what and when to display on a form.
Some client APIs are deprecated in the current release of model-driven apps. Ensure that you are aware of these APIs as you write your client-side code for model-driven apps. More information: Deprecated client APIs
