Save the file as scriptEditor.htm in the Configuration/Floaters folder.
Both
div
tags use the
style
attribute to specify the position (
absolute
), size (
width:422px
and
height:181px
),
and default
visibility
setting (
visible
) of the floating panels. The
blanklayer
panel uses the
center
attribute
and a series of break (
br
) tags to position the text in the center of the panel. The
scriptlayer
panel creates a form
with a single
textarea
to display the selected JavaScript code. The
textarea
tag also specifies that when an
onBlur
event occurs, indicating that the selected code has changed, the
updateScript()
function is called to write the
changed text back to the document.
Writing the JavaScript code
The JavaScript code for the Script Editor consists of one floating panel function that Dreamweaver calls,
selection-
changed()
, and one user-defined function,
updateScript().
selectionChanged(): is a script marker selected?

selectionChanged()
function determines whether a script marker has been selected in Design view. A script
marker appears in Design view if there is a JavaScript routine in the body section of a document and if Scripts is
selected on the Invisible Elements section of the Preferences dialog box. The following figure shows a script marker
