on mouseDown (event handler) 181
When the movie plays back as an applet, an on keyUp handler always traps key presses, even if the
handler is empty. If the user is typing in an editable field, an
on keyUp handler attached to the
field must include the
pass command for the key to appear in the field.
Where you place an
on keyUp handler can affect when it runs, as follows:
• To apply the handler to a specific editable field sprite, put it in a behavior.
• To apply the handler to an editable field cast member in general, put it in a cast member script.
• To apply the handler to an entire frame, put it in a frame script.
• To apply the handler throughout the entire movie, put it in a movie script.
You can override an
on keyUp handler by placing an alternative on keyUp handler in a location
that Lingo checks before it gets to the handler you want to override. For example, you can
override an
on keyUp handler assigned to a cast member by placing an on keyUp handler in a
sprite script.
Example
This handler checks whether the Return key was released and if it was, sends the playhead to
another frame:
-- Lingo syntax
on keyUp
if (_key.key = RETURN) then _movie.go("AddSum")
end keyUp
// JavaScript syntax
function keyUp() {
if (_key.keyCode == 36) {
_movie.go("AddSum");
}
}
