Try using your original handler function even though the text field is
now HTML-enabled, because removing the last 'htmlText' character simply
pops off a (non-visible) closing tag's (likely </textformat>) final
angle bracket.
If this method destroys HTML formatting on your text, you can always use
the following code.
function getTextMinusOneCharacter(targetText:String,
presumeHTML:Boolean):String
{
var lastBracketIndex:Number = targetText.lastIndexOf('<');
while (lastBracketIndex > 0 && targetText.charAt(lastBracketIndex - 1)
== '>')
{
lastBracketIndex = targetText.lastIndexOf('<', lastBracketIndex -
1);
}
lastBracketIndex--;
if (lastBracketIndex > 0 && presumeHTML !== false)
{
targetText = targetText.slice(0, lastBracketIndex) +
targetText.slice(lastBracketIndex + 1);
}
else
{
targetText = targetText.slice(0, targetText.length - 1);
}
return targetText;
}
this.textBox.onChanged = function():Void
{
if (this.maxscroll > 1)
{
this.htmlText =
this._parent.getTextMinusOneCharacter(this.htmlText);
}
};
