Description

The getBeginIndex() method identifies the beginning of a selection. To determine the span

of characters currently selected, use both getBeginIndex() and getEndIndex().

Example

The following example creates a string representing the currently selected characters and

then displays that string in the Output window:

var firstChar = Selection.getBeginIndex();

var lastChar = Selection.getEndIndex();

// eval() is required because Selection.getFocus() returns a string

var currentSelection =

eval(Selection.getFocus()).text.substring(firstChar, lastChar);

trace(currentSelection);

The following code extends the current selection by one character to the left:

Selection.setSelection(Selection.getBeginIndex()-1, Selection.getEndIndex());
