Getting back to this question I had back on Aug 1, thanks for the ideas.
I've built a basic HTML text editor in Flash using the TextFormat class.
Since I need to save the resulting HTML string back to a database, it
works great.
However, now I need to insert images into the HTML - which isn't
supported by the TextFormat class. So I was thinking I could just
insert an img tag string into the textField using
TextField.replaceSel(), like this:
test_txt.replaceSel("<img src=\"mountains.jpg\" width=\"350\"
height=\"120\" />");
So that part works fine, but when I re-render the textField, the image
does not show (doesn't render as HTML), it shows the literal <img
scr=...etc. characters in the textField (even though it is an HTML
textfield). I thought maybe I needed to re-render the textfield, so I
left the frame and then jumped back to it, and it still shows the
literal HTML. So in testing the value of the html TextField, I found
the <> and \" characters I inserted have been changed to encoded
entities in the HTML string:
<img src="mountains.jpg" width="350"
height="120" />
Why is that and how can I fix this? It would be pretty messy to use
the XML object to decode those entities - why are they getting rendered
that way in the first place?
Thanks,
