dom.getSelection()
Availability
Dreamweaver 3.
Description
Gets the selection, which is expressed as character offsets into the document’s source code.
Arguments
{bAllowMultiple}
• The bAllowMultiple argument, which is optional, is a Boolean value that indicates whether
the function should return multiple offsets if more than one table cell, image map hotspot, or
layer is selected.
If this argument is omitted, it defaults to
false.
Returns
For simple selections, an array that contains two integers. The first integer is the character offset
of the opening of the selection. The second integer is the character offset at the closing of the
selection. If the two numbers are the same, the current selection is an insertion point.
For complex selections (multiple table cells, multiple layers, or multiple image map hotspots), an
array that contains 2
n integers, where n is the number of selected items. The first integer in each
pair is the character offset of the opening of the selection (including the opening
TD, DIV, SPAN,
LAYER, ILAYER, or MAP tag); the second integer in each pair is the character offset of the closing of
the selection (including the closing
TD, DIV, SPAN, LAYER, ILAYER, or MAP tag). If multiple table
rows are selected, the offsets of each cell in each row return. The selection never includes the
TR
tags.

Availability
Dreamweaver 3.
Description

dreamweaver.getDocumentDOM() function returns.
Returns
An array that contains two integers. The first integer is the character offset of the beginning of the
tag, text, or comment. The second integer is the character offset of the end of the node, from the
beginning of the HTML document.
