jquery: keypress, ctrl+c (or some combo like that)

会有一股神秘感。 提交于 2019-11-26 12:20:32
I'm trying to create shortcuts on the website i'm making. I know I can do it this way: if(e.which == 17) isCtrl=true; if(e.which == 83 && isCtrl == true) { alert('CTRL+S COMBO WAS PRESSED!') //run code for CTRL+S -- ie, save! e.preventDefault(); } But the example below is easier and less code, but it's not a combo keypress event: $(document).keypress("c",function() { alert("Just C was pressed.."); }); So I wanna know if by using this second example, I could do something like: $(document).keypress("ctrl+c",function() { alert("Ctrl+C was pressed!!"); }); is this possible? I've tried it and it

Removing the delay after KeyDown event?

≯℡__Kan透↙ 提交于 2019-11-26 11:40:54
问题 When I hold a key in my game to move my player: public void MainForm_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Up) { Player.MoveUp(); } } The player instantly moves one step as soon as I press the down arrow, and then pauses for a short duration before starting to smoothly move again. Why\'s this? How can I prevent it? 回答1: The answer in the proposed duplicate is incorrect, unfortunately. It doesn't ignore repeated KeyDown events, and so will gradually increase the "delta

How to use pygame.KEYDOWN?

问题 So, my question was most likely already asked, but I didn\'t know what to search for, and didnt find much. So, my problem is, I made 2 functions, which would check for an event def get_pygame_events(): pygame_events = pygame.event.get() return pygame_events and def get_keys_pressed(self): keys_pressed = get_pygame_events() #pygame.event.get(pygame.KEYDOWN) # print(keys_pressed) keys_pressed_list = [] for event in keys_pressed: if event.type == pygame.KEYDOWN: if event.key == K_LEFT: keys

jQuery key code for command key

主宰稳场 提交于 2019-11-26 10:33:30
问题 I have read jQuery Event Keypress: Which key was pressed? and How can i check if key is pressed during click event with jquery? However my question is if you can get the same key event for all browsers? Currently I know that Firefox gives the command button (Mac) the code 224 while Chrome and Safari give it the value 91. Is the best approach to simply check what browser the user is using and base the key pressed on that or is there a way so that I can get 1 key code across all browsers? Note

OSX: Detect system-wide keyDown events?

[亡魂溺海] 提交于 2019-11-26 07:56:34
问题 I\'m working on an typing-tutor application for Mac OSX that needs to have keystrokes forwarded to it, even when the application is not in focus. Is there a way to have the system forward keystrokes to the app, possibly through NSDistributedNotificationCenter? I\'ve googled myself silly, and haven\'t been able to find an answer... EDIT: Sample code below . Thanks @NSGod for pointing me in the right direction -- I ended up adding a global events monitor using the method

Changing the keypress

问题 In an input box or contenteditable=true div, how can I modify a keypress for the letter \"a\" to return a keybress for the letter \"b\"? I.e., every time you type the letter \"a\" in the div, the output is actually the letter \"b\". I\'m not that concerned with a solution that works in IE--just one that works in Safari, Chrome, & FF. In Chrome, I can see that a keypress event has the properties \"charCode\", \"keyCode\", and \"which\", all of which get assigned the keypress event number. If I

How can I capture KeyDown event on a WPF Page or UserControl object?

梦想与她 提交于 2019-11-26 06:40:48
问题 I have a Page with a UserControl on it. If the user presses Esc while anywhere on Page I want to handle. I thought this would be as easy as hooking up the PreviewKeyDown event, testing for the Esc key, and then handling it. However, when I placed I breakpoint in the event handler I found it was never getting called. I thought perhaps the UserControl might be getting hit, so I tried PreviewKeyDown there... same result. Does anyone know the proper place to test for a KeyDown or PreviewKeyDown

Up, Down, Left and Right arrow keys do not trigger KeyDown event

依然范特西╮ 提交于 2019-11-26 00:55:04
问题 I am building an application where all the key input must be handled by the windows itself. I set tabstop to false for each control witch could grab the focus except a panel (but I don\'t know if it has effect). I set KeyPreview to true and I am handling the KeyDown event on this form. My problem is that sometimes the arrow key aren\'t responsive anymore: The keydown event is not fired when I pressed only an arrow key. The keydown event is fired if I press an arrow key with the control

Python simulate keydown

断了今生、忘了曾经 提交于 2019-11-26 00:47:19
问题 After searching for several hours i´m wondering if its possible to simulate a keydown press on the keyboard. For example I want my program to hold the x key down for five seconds so when I run it in notepad it would look like to see something like this: xxxxxxxxxxxxx . I tried around with different pieces of code on the internet, the best thing I could find so far is this: import ctypes import time user32 = ctypes.windll.user32 inputhex = raw_input(\"Please enter your desired key\'s code (HEX
