Things You Must Know Before Writing a NetSuite Client Script
NetSuite client scripts are powerful for enhancing user interactions, validating fields, and automating actions directly in the browser. However, they come with certain constraints and best practices that every developer should understand before diving in. Here are the key things you must know:
1) Client Scripts Work Only in UI Context
Client scripts do not run during non-UI contexts such as CSV imports, Web Services (SuiteTalk), or Map/Reduce scripts. If you need similar logic to run in those contexts, consider using User Event (UE) scripts
2) Runs Under the Current User’s Role
Unlike User Event scripts that can run with administrator privileges, client scripts execute under the permissions of the currently logged-in user. If your logic requires elevated permissions, combine with a backend Suitelet.
3) Execution Mode
Client scripts only execute in edit mode. If you have a deployed client script with a pageInit entry point, that script does not execute when you view the form. It executes when you click Edit.
4) No Post-Submit Logic
Client scripts cannot execute logic after a record is saved. For any post-save processes, you must use User Event scripts (afterSubmit) or scheduled scripts.
5) Deployment Options
Client scripts can be deployed on:
- Specific record types (e.g., Sales Order, Customer)
- Specific custom forms
6) Supported Events & Execution Order
Common entry points in client scripts include:
pageInitsaveRecordvalidateFieldfieldChangedpostSourcinglineInitvalidateLinerecalc
Plan your logic flow carefully based on the sequence of these events.
7) Avoid Heavy Logic
Client scripts run in the user’s browser. Any heavy computation, large loops, or unnecessary API calls will freeze the UI. Offload heavy logic to Suitelets or server-side scripts whenever possible.
8) Test Across Roles and Browser
Since client scripts execute with the logged-in user’s permissions, test the script under all roles that will access the form. Also, verify compatibility with supported browsers.
Conclusion
Client scripts are excellent for improving the user experience, but they’re best when combined with other script types for backend logic and data integrity. By understanding these limitations and best practices, you can write robust, user-friendly scripts that improve NetSuite workflows.
