Whenever you want to out put the array you wipe the htmlText before you run
the output loop:
mainText.htmlText = "";
for(var i:uint = 0; i < cueArray.length; ++i) {
mainText.htmlText += "<b>" + cueArray[i] + "</b>";
}
This might be a bit inefficient, setting the .htmlText repeatedly would, I
suspect, fire a lot of HTML class events. So it might be better to have a
separate String variable that you set first and then fire at the HTML
instance:
// init the string
var html2render:String;
// displaying the cueArray
html2render = "";
for(var i:uint = 0; i < cueArray.length; ++i) {
html2render += "<b>" + cueArray[i] + "</b>";
}
mainText.htmlText = html2render;

Subject: Re: [Flashcoders] Basic loop problem (with end of message)
Thanks to everyone for your help. This gets me closer to what I'm looking
for.
Unfortunately, there's a complicating factor: if the user scrubs across the
same point in the video again, they end up with duplicates/triplicates of
the list.
Since we actually want people to do this, I'm looking for a solution that
will replace the existing text with the full array on each cuePoint event.
I thought that my original code would do this - unless there's a better way
of achieving this?
Hope this makes sense and thanks again.
