| retrieve the index of the first selected character in the text field with keyboard focus | | Selection.getBeginIndex()
Returns The index of the first character in the current selection (highlighted block of text). If no text field has keyboard focus, it returns -1. If a text field has focus but no characters are selected, it returns the value of Selection.getCaretIndex( ). 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()); See Also Selection.getCaretIndex( ), Selection.getEndIndex( ), TextField.replaceSel( ) |
