A. g_form.addInfoMsg()
B. g_form.showFieldMessage()
C. g_form.showFieldMsg()
D. g_form.addInfoMessage()
Explanation:
ServiceNow provides multiple ways to show messages to users in the UI, and the correct method depends on whether the message is meant for the top of the form or next to a specific field. In the GlideForm client API, ServiceNow documents g_form.addInfoMessage(String message) as the method that adds an informational message to the top of the form. This is the standard client-side approach for showing an info banner at the top area of the current form and is commonly used in Client Scripts and UI Policies to inform users about guidance, rules, or results of client-side logic. ServiceNow’s GlideForm documentation specifically names this method and provides examples of its usage via g_form. By contrast, g_form.showFieldMsg() (and similarly named field-message functions) are used to display messages associated with a particular field location, not as a general blue banner at the top of the form. The option g_form.addInfoMsg() is not the documented default method name. Therefore, the correct answer is g_form.addInfoMessage().
