Form Element Functions

Many user interface events occur when a user interacts with a form. Events such as changing a field value (onChange) or positioning the mouse pointer over a table (onMouseOver) can initiate JavaScript functions. As a designer of a form, you can use form element functions to achieve the following and other goals:

• Dynamically control form elements based on events.
• Get data from a field or table.
• Set the data in a field or table.
• Use logic to assist users with navigating potentially complex options. For example, you can use functions to update a list of cities according to the Country a user selects.
• Assist users with minimizing data-entry errors.

This section lists predefined JavaScript functions that you can use in fields on start request and interaction request forms.
