Hello @mshiraz826 ,

Below are the Types of client script with detailed explanation :

Client Script Type	When It Runs	Purpose
onLoad	Executes when the form is loaded/opened	Used to initialize the form, set default values, hide/show fields, make fields mandatory or read-only, and display messages.
onChange	Executes whenever the value of a specified field changes	Used to validate input, populate fields automatically, show/hide fields, and implement dynamic form behavior based on field values.
onSubmit	Executes when the user submits, saves, updates, or orders the form	Used to validate data before submission and prevent form submission if required conditions are not met.
onCellEdit	Executes when a field is edited directly in a list view	Used to validate or control inline list edits before the change is saved.

Also If you want examples for each let me know !

If my response helped mark as helpful and accept the solution.
