Understanding Client-Side APIs

Usama — Fri, 28 Feb 2025 12:46:25 GMT

Client-Side APIs run in the user's browser and help interact with forms, fields, and UI elements without making unnecessary server calls. They are commonly used in:

GlideList (g_list) – List Customization API

Used to manipulate list views dynamically.

✔ Example: Refresh a list

g_list.refresh();

Example: Add a filter to a list

g_list.setFilter('priority=1');

Best Practices for Using Client-Side APIs

Optimize Performance – Minimize GlideAjax calls to avoid excessive server requests.
Use Conditions – Only execute scripts when necessary (if (g_form.getValue('state') == 'New')).
Test on Different Forms – Ensure scripts work across different scenarios.

Conclusion

Client-Side APIs are essential for enhancing ServiceNow's UI/UX by making forms dynamic and interactive. Mastering these APIs helps in building efficient, user-friendly applications that improve productivity.
