You are editing the scripting properties of a file that is compiled in a publication with HTML Executable.
The publication or ebook can be extended via scripting functionality. HTML Executable has its own script language called “HEScript”: you can write your own scripts in order to control the behavior of your ebook and actually do what you want.
Several reasons why you can use scripting:
Some scripts contain several functions that actually play the role of “events”: when an event is triggered, the publication will execute the associated function.
Script for HTML pages contains events as:
You can therefore associate a script to an HTML page: when this HTML page is viewed, the associated script is loaded by the publication. Then when an event occurs, the related function is executed. Thus, you may respond to a specific event with your own actions.
In the Associated Script tab of the File Properties window, you can choose which script should be associated to the selected HTML page(s). All existing scripts are available in the list: just select the one you wish.
To manage HEScript scripts, please go to the Application Behavior tab ⇒ User Scripts page.
