How to disable default browser navigation with Space in Flex

问题

I have defined a keyboard shortcut that uses space. After I have pressed the shortcut two things happen: some random navigation in my app and also the code in my eventHandler from the keyboard shortcut.

I found THIS table with browser keyboard shortcuts and obviously space sometimes is used for navigation. So is there a way to stop the navigation with space in Flex, because eating the spacebar button doesn't seem to work:

  FlexGlobals.topLevelApplication.addEventListener(KeyboardEvent.KEY_DOWN,
                                                     ignoreSpaceNavigation);

  private static function ignoreSpaceNavigation(event:KeyboardEvent):
     event.preventDefault();
     event.stopImmediatePropagation();
  }

So any ideas how to stop the navigation? (I really want to use space for that keyboard shortcut!)

回答1:

Try to set event listener on a stage and use capture

stage.addEventListener(KeyboardEvent.KEY_DOWN, ignoreSpaceNavigation, true);
