Question

I'm making simple editor. And I want that, let write replacing colorless text to color text from RichEditableText when I will write any text.
For example:
PHP --> <s:span color="#FF0000">PHP<s:span>
This codes not work:
editorum.text = editorum.text.replace('PHP','<s:span color="#FF0000">php<s:span>');
Editorum is: <s:RichEditableText id="editorum" ></s:RichEditableText>

Answer 1

Instead of this line:
editorum.text = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>');
Try something like this:
var text : String = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>')
editorum.textFlow = TextConverter.importToFlow(text, TextConverter.TEXT_FIELD_HTML_FORMAT);
Basically, you need to convert the HTML into something that the TLF Framework will understand. Read some docs on textFlow and the TextConverter
