If a modal dialog box is displayed as a result of pressing or sending a key, the KeyDown and KeyPress events occur, but the KeyUp event doesn't occur. To find out the ANSI character corresponding to the key pressed, use the KeyPress event. If a keystroke causes the focus to move from one control to another control, the KeyDown event occurs for the first control, while the KeyPress and KeyUp events occur for the second control. The KeyUp event occurs after any event for a control caused by pressing or sending the key. The Esc key if the form has a command button for which the Cancel property is set to Yes. The Enter key if the form has a command button for which the Default property is set to Yes. The KeyUp event does not occur when you press: The numeric keypad and keyboard number keys. Navigation keys, such as Home, End, PgUp, PgDn, Up arrow, Down arrow, Right arrow, Left arrow, and Tab.Ĭombinations of keys and standard keyboard modifiers (Shift, Ctrl, or Alt keys). If you press and hold down a key, the KeyDown and KeyPress events alternate repeatedly ( KeyDown, KeyPress, KeyDown, KeyPress, and so on) until you release the key, then the KeyUp event occurs.Īlthough the KeyUp event occurs when most keys are pressed, it is typically used to recognize or distinguish between:Įxtended character keys, such as function keys. Other DOM events are available as well, but for the events above, Meteor has taken some care to ensure that they work uniformly in all browsers. For example, you may want the key combination Ctrl+X to always perform the same action on a form. keypress is most useful for catching typing in text fields, while keydown and keyup can be used for arrow keys or modifier keys. You can respond to specific keys pressed in the form, regardless of which control has the focus. With this property setting, all keyboard events occur first for the form, and then for the control that has the focus. A form can have the focus only if it has no controls or all its visible controls are disabled.Ī form will also receive all keyboard events, even those that occur for controls, if you set the KeyPreview property of the form to Yes. įor both events, the object with the focus receives all keystrokes. To run a macro or event procedure when these events occur, set the OnKeyUp property to the name of the macro or to. If you need to test for the Shift argument, you can use one of the following intrinsic constants as bit masks:ĪcShiftMask The bit mask for the Shift key.ĪcCtrlMask The bit mask for the Ctrl key. The state of the Shift, Ctrl, and Alt keys at the time of the event. You can prevent an object from receiving a keystroke by setting Ke圜ode to 0. To specify key codes, use the intrinsic constants shown in the Object Browser. Parameters NameĪ key code, such as vbKeyF1 (the F1 key) or vbKeyHome (the Home key). SyntaxĮxpression A variable that represents a TextBox object. This event also occurs if you send a keystroke to a form or control by using the SendKeys action in a macro or the SendKeys statement in Visual Basic. The KeyUp event occurs when the user releases a key while a form or control has the focus. To restore the user’s ability to add tasks to their lists, find the following code inside the “submit form” event for the “addTodo” template: 'submit form' : function ( event ) Todos. Then, back in the submit form event, add a callback function to the Meteor.call statement. You don’t have to do anything too complex – for these methods, I’ve mostly opted for simplicity – but it nevertheless helps to practice writing code on your own, without the hand-holding of a book. But I haven't found a way to intercept those events outside of something like the keyup and keydown events you can process as part of an input field, which doesn't help me. ![]() “removeListItem”, for deleting to-do list items.“changeItemStatus”, for marking tasks as complete or incomplete. ![]() “updateListItem”, for saving changes to to-do list items.“createListItem”, for adding to-do list items to lists.There are four methods we need to create: With that in mind, try implementing the remaining methods without reading this chapter. This will allow us to cover a couple of new details, but it’s mostly a matter of repeating stuff that we’ve already talked about in this past. The only thing left is to create some methods that will restore the functionality our application’s features.
