Here are some use cases and resources for practicing Client Scripts, Business Rules, Script Includes, and Glide Ajax in ServiceNow:
Use Cases
1. Client Script
- Auto-populate Fields: Write a client script to auto-populate fields based on user input. For example, automatically set a department based on the user's selected location.
- Field Validation: Implement field validation to ensure that a phone number follows a specific format or that a mandatory field is filled out before submission.
- Dynamic Form Behavior: Show or hide fields based on the value of a drop-down list or other field selections.
2. Business Rule
- Auto-Assign Records: Create a business rule that auto-assigns a record to a specific user or group based on the record's field values when it's created or updated.
- Change State and Notify: Implement a business rule to change the state of a record and send an email notification when the state changes to 'Resolved'.
- Data Validation: Write a business rule to validate data before a record is saved, such as ensuring that a change request has an associated change plan.
3. Script Include
- Reusable Functions: Create a script include with reusable functions for common tasks, such as calculating dates or processing text.
- Custom API: Build a script include to provide custom API endpoints that can be called from other server-side scripts or client scripts.
- Data Transformation: Develop a script include to transform or format data in a specific way before saving it to a record.
4. Glide Ajax
- Dynamic Data Retrieval: Use Glide Ajax to fetch and display additional data in a form based on user input, such as retrieving related records or additional details from a server-side script.
- Server-side Processing: Implement server-side logic to process data and return results to the client, such as calculating and returning a result based on user input.
- Real-time Data Updates: Use Glide Ajax to update fields or UI elements dynamically without reloading the form.
