Hello,
the text length is 0, becaus at this time, there is no linebrake in the
textfield.
The Key-Listener is faster than the textfield.
Try this:
_root.createTextField("txt", 1, 0, 0, 100, 100);
_root.txt.type = "input";
_root.txt.multiline = true;
_root.txt.wordWrap = true;
_root.clearText = function(id) {
clearInterval(_root.clearTextIntervalId);
_root.txt.text = "";
};
_root.keyListener = new Object();
_root.keyListener.onKeyDown = function() {
if (Key.getCode() == Key.ENTER) {
_root.clearTextIntervalId = setInterval(_root.clearText, 10);
}
};
Key.addListener(_root.keyListener);

God knows why this is such a hassle:
I have a chat app that sends messages when the user hits enter. The
input field is multiline (and needs to be, for the sake of elegance).
Hitting enter inserts a line break in the text regardless of what i do
right now. The method reads something like this:
function clearText() {
chat_input.text = "";
trace(chat_input.text.length);
}
kl = {};
Key.addListener(kl);
kl.onKeyDown = function() {
if (Key.isDown(Key.ENTER)) {
clearText();
}
};
After clearText, The input field has 2 blank lines and a text length of
0. I'm hugely confused here, and kind of freaked out.
If it's got a text length of 0 maybe it doesn't actually have two blank
lines, it's just not reset its height to where it was before clearing the
text. Try storing its _width and _height and resetting those as part of your
clearText function.
