A text page can contain one or more calls to JavaScript™ functions, which can be embedded in the text page or in external JavaScript files that are called by the text page. JavaScript can do many things to the page while it is being rendered.

JavaScript functions are typically called by:

• Visitor interactions, such as clicking a button.
• The page's onLoad and onUnload rendering events.

RTV has a number of options to control how it renders JavaScript. You can decide how you would like to see the visitor impression by using these options.

To disable all JavaScript playback, set the allow Javascript to run option to disabled. If the page is designed with a significant use of JavaScript and this option is disabled, the user impression that is rendered by RTV differs significantly from what the visitor saw.
