menu

问题 I use a context menu in an android App to prompt the user to select a Filter. The relevant code is: TextView someView = (TextView) findViewById(id.some_view); registerForContextMenu(someView); ... @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.setHeaderTitle("Select a Filter"); menu.add(0, 0, 0, "Filter1"); menu.add(0, 1, 1, "Filter2"); menu.add(0, 2, 2, "Filter3"); } @Override

问题 I am building a mobile website, and the client wants a menu bar at the top. The menu is very wide, so he wants it to be horizontally scrolled by dragging it left and right. app.ft.com has similar functionality (although you must view this on on an iPhone to see it working) Does anyone know of a jQuery / jqTouch script that can achieve this? I have tried scrollTouch, but that only scrolls the whole page, not just a menu. 回答1: Take a look at this http://plugins.jquery.com/project/Touchwipe
