Which type of scripts run in the browser?

Scripts that run in the browser (client-side) help control UI behavior, form validation, and field

interactions in real-time without needing a server request.

Types of Client-Side Scripts in ServiceNow:

✅ Client Scripts

Run directly in the user's browser.

Used for form validation, auto-populating fields, or UI interactions.

Example:

javascript

CopyEdit

function onLoad() {

g_form.setValue('priority', '2');

}

✅ UI Policies

Control field visibility, mandatory status, and read-only state dynamically.

Example: If category = Hardware, make Serial Number field mandatory.
