InServiceNow,Client Scriptsare used to execute JavaScript codeon the client-side (browser)to control form behavior, validate data, or enhance user interaction.
Types of Client Scripts in ServiceNow:There arefourtypes of Client Scripts supported in ServiceNow:
onLoad (Option D)
Runswhen a form loads.
Used to pre-fill fields, hide/show elements, or set default values.
Example: Automatically setting the "Priority" field toHighwhen a new incident is created.
onChange (Option F)
Runswhen a specific field value changes.
Used for dynamic form behavior, such as making fields mandatory based on another field's value.
Example: If "Category" is changed to "Hardware," then show the "Hardware Type" field.
onSubmit (Option A)
Runswhen the form is submitted.
Used for final validation before allowing submission.
Example: Preventing submission if a mandatory field is left empty.
onCellEdit (Option C)
Runswhen a cell value is edited inline in a list view.
Used to trigger immediate validation or updates without opening the full form.
Example: Displaying an alert when a user directly changes an incident's priority from a list view.
Why Are the Other Options Incorrect?B. onUpdate
No "onUpdate" client script type exists in ServiceNow.
"onUpdate" is relevant inBusiness Rules, not Client Scripts.
E. onEdit
No "onEdit" client script type exists.
Similar functionality can be achieved with "onChange" or "onCellEdit" scripts.
G. onSave
No "onSave" client script type exists.
"onSubmit" handles validation before saving a record.
