Which of the following is NOT a way to execute client scripts?

1. OnChange

2. OnLoad

3. OnClick

4. OnSubmit

The correct answer is: OnClick

Client scripts in ServiceNow are designed to run in the user's browser and allow for dynamic interactions and validations. These scripts can be triggered by specific events within the user interface, which include various types of actions a user may take. OnChange, OnLoad, and OnSubmit are all valid ways to execute client scripts. An OnChange client script runs when the value of a specific field changes, enabling you to react to user input and modify other fields or provide feedback. OnLoad scripts run when a form is first displayed to the user, allowing for pre-population of data or setup of form elements. OnSubmit scripts are executed just before the form is submitted, often used for validation or to ensure that certain conditions are met before data is sent to the server. OnClick, however, is not a recognized event type for triggering client scripts in ServiceNow. While buttons can be configured to have client-side actions associated with them, this does not correspond to a native client script event like the others mentioned. This distinction clarifies why OnClick does not function as a trigger for client scripts in the context of the question. Therefore, it is identified correctly as the option that does not represent a method to execute client scripts.
