The central JavaScript files can be viewed and edited under"JavaScript" in the layout/design area.
By clicking on the"JavaScript files" button, the design.js of the project opens directly for editing. Other JS files can also be opened for editing via the directory structure on the left.
All JS files of a project are stored in the scripts directory. You can open, display, copy, etc. these for editing using the usual file functions.
You can define the corresponding JavaScript functions by editing a JS file . This is done directly in the source code, which will not be discussed further here. The general rules for CSS apply (see e.g. SELFHTML article "JavaScript/DOM").
