keydown

I'm pretty new when it comes to getting my head around JS functions. Everything I've used before, I've tended to use as-is, but I've been trying to combine and modify a function to get a Div to toggle (height & opacity) on a specific keypress. I have the first part (can get the div to show on a 'ctrl + o' combo), but can't combine it with an if statement to show or hide, based on current display status. Current working 'show only' JS: $(document).keydown(function (e) { if (e.keyCode == 79 && e.ctrlKey) { document.getElementById('thediv').style.height = 'auto'; document.getElementById('thediv')

I have many NSTextFields and I want to know, if the user has pressed one of the arrow keys while editing one of them. The function override func keyDown(theEvent: NSEvent) { switch theEvent.character { case NSRightArrowFunctionKey: println(1) moveGor(NSRightArrowFunctionKey) case NSLeftArrowFunctionKey: moveGor(NSLeftArrowFunctionKey) case NSUpArrowFunctionKey: moveVert(NSUpArrowFunctionKey) case NSDownArrowFunctionKey: moveVert(NSDownArrowFunctionKey) default: super.keyDown(theEvent) } } doesn't seem to work. Is there any other way to do that in swift? EDIT: I have the extension for NSEvent :

(My first question here!) Hi, I am kind of beginner in c#. I tried to build a simple timer (in Windows.Forms). I made a label which indicates the time, and used the StopWatch class (from system.diagnostics). The trigger event for starting / stopping the stopwatch is the spacebar KeyDown event. After the second tap the stopwatch stops and Label.text is assigned to the Stopwatch.Elapsed value. I want to continuously update the label, but I don't know how. If I make while(StopWatchName.IsRunning) in the event itself, the event will indefinitely continue and won't respond for the second tap.

I have this piece of code which allows a user to leave comments on a list of items. I created a directive and listen to keydown in order to let the user submit a comment if keyCode == 13 . Not sure if I should include the code to post a comment within the directive. What is the best way to communicate between controllers and directives? I also check whether or not the input is empty before submitting the comment. It works but not sure this is Angular best practice? Here is my plunker . You generally don't want your directives knowing anything about your controller, so the best(Angular) way of

I need to only allow one character to be entered into the editable datagridview cells (every other column, the odd-numbered ones, are editable); if the user adds a second character while in one of these cells, the cursor should move to the next cell down and put that second value there (pressing again on that key moves down again, and so forth). If at the bottom of the grid (the 12th row), it should move to row 0 and also move two columns to the right. I tried doing this: private void dataGridViewPlatypus_KeyDown(object sender, KeyEventArgs e) { var currentCell = dataGridViewPlatypus

I have the following code which does not show the MessageBox when enter/return is pressed. For any other key(i.e. letters/numbers) the MessageBox shows False. private void cbServer_TextChanged(object sender, EventArgs e) { if (enterPressed) { MessageBox.Show("Enter pressed"); } else MessageBox.Show("False"); } private void cbServer_Keydown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return) { enterPressed = true; MessageBox.Show("Enter presssed: " + enterPressed); } else enterPressed = false; } Any ideas? EDIT: Above code, I thought the issue was with the

I need to set up an <input type="text" /> so that it will accept only numeric chars, backspace, delete, enter, tabs and arrows. There's a lot of exemple around there, i started with something similar to this: function isNumericKeyCode (keyCode){ return ( (keyCode >= 48 && keyCode <= 57) //standard keyboard ||(keyCode >= 96 && keyCode <= 105)) //Numpad } $('#myTextBox').keydown(function(e){ var handled = true; var keyCode = e.keyCode; switch(keyCode){ //Enter and arrows case 13: case 37: case 38: case 39: case 40: doSomethingSpecialsWithThesesKeys(); break; default: handled = false; break; } if
