I have : <p ><a href="http://www.example.com" target="_blank"><span>link example</span></a></p> into TextFlow

I need  collect the href data to an textInput when select  'link example' words.

I add a Listener:

TextFlow.addEventListener(SelectionEvent.SELECTION_CHANGE,selectionChangeListener,false,0,true);

and :

private function selectionChangeListener(evt:SelectionEvent):void
             {

                 /// how can I read href tag  ?

                        myTxt.text = evt ???????

              }

thanks

Hi!

... it is big sh*t reading the href proprerty... but it works for me...=)

... the basic is that you have to find in the textFlow the LinkElement, check is it in the selection range, and if yes, that it is very easy to read the href property of it ... =)

        private function getLinkPropertyInTheSelectionRange():String
        {
                    if (selectedElementRange.firstParagraph == selectedElementRange.lastParagraph)
                        if (selectedElementRange.firstParagraph.numChildren == 1)
                            return selectedElementRange.firstParagraph.getChildAtIndex(0) is LinkElement ?
                                LinkElement(selectedElementRange.firstParagraph.getChildAtIndex(0)).href :
                                null;
                        else
                            for (var i:int = selectedElementRange.firstParagraph.numChildren; i-- > 0;)
                            {
                                if (selectedElementRange.firstParagraph.getChildAtIndex(i) is LinkElement &&
                                    elementIsInTheSelection(selectedElementRange.firstParagraph.getChildAtIndex(i)))
                                        return LinkElement(selectedElementRange.firstParagraph.getChildAtIndex(i)).href;
                            }
                    return null;

        }


        private function elementIsInTheSelection(flowElement:FlowElement):Boolean
        {
            var absoluteStart:int = flowElement.getAbsoluteStart();

            var isIn:Boolean =
                    selectedElementRange.absoluteStart == selectedElementRange.absoluteEnd ?
                        absoluteStart < selectedElementRange.absoluteStart &&
                        absoluteStart - flowElement.parentRelativeStart + flowElement.parentRelativeEnd > selectedElementRange.absoluteEnd:
                        absoluteStart <= selectedElementRange.absoluteStart &&
                        absoluteStart - flowElement.parentRelativeStart + flowElement.parentRelativeEnd >= selectedElementRange.absoluteEnd;

//            trace('        TextEditor.elementIsInTheSelection    ',
//                flowElement,'\t',isIn,absoluteStart,'\t',
//                absoluteStart + flowElement.parentRelativeStart,    selectedElementRange.absoluteStart,        '\t',
//                selectedElementRange.absoluteEnd,                    absoluteStart + flowElement.parentRelativeEnd);

            return isIn;
        }
