ServiceNow Client Script Tutorial | ServiceNow client script examples
Client scripts allow the system to run JavaScript on the client (web browser) when client-based events occur, such as when a form loads, after form submission, or when a field changes value.
Use client scripts to configure forms, form fields, and field values while the user is using the form. Client scripts can:
– make fields hidden or visible
– make fields read-only or writable
– make fields optional or mandatory based on the user’s role
– set the value in one field based on the value in other fields
– modify the options in a choice list based on a user’s role
– display messages based on a value in a field
