问题 Firstly, I'm a complete beginner, so I do not have any experience, I have however searched all the possible places these last 2 days for a resolve, and could not find it. I'm using this on a Raspberry PI 3 with Raspbian. I'm trying to build a simple code in Python 3.6 that will do the following: When pressing a keyboard key: 1.it should print 'press' if the key was pressed, without repeating. (if the key is being held down, it should print 'press' only once and stop). 2.it should print

JQuery - Android - The 'Keyup' Event Does Not Work On Backspace In Chrome

由 心已入冬 提交于 2019-12-10 17:15:17
问题 I am wondering why the backspace/ delete button does not detect a keyup event in jQuery. I find this odd as it is useful and should be supported. Are there any alternatives to this? This is only happening in Android - Chrome. 回答1: You can actually fix this by attaching an event listener to the input. var inputBox = document.getElementById('inputId'); inputBox.addEventListener(‘input’, function() { exampleFunc(); }, false); Cheers 来源： https://stackoverflow.com/questions/24557402/jquery-android

Weird KeyUp behaviour (main form handles events from child?!)

由 ￣綄美尐妖づ 提交于 2019-12-10 16:05:49
问题 The problem: KeyUp is handled by the grid in main window ( Grid_KeyUp ) Main window shows a child window (e.g. MessageBox.Show(...) ) User presses [Return] ( Keys.Return ) to close the MessageBox Main window actually GETS the KeyUp event from that keypress in MessageBox I have a very simple isolated sample that shows the problem I am having. Just create an empty WPF project and use this XAML: <Grid KeyUp="Grid_KeyUp"> <Button Click="Button_Click"></Button> </Grid> And the code-behind: public

I am making a simple game and I use the following code to detect cursor keys: protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if (Connection == null || Connection.IsOpen == false) return true; Thread.Sleep(SleepTime); switch (keyData) { case Keys.Up: GoForward(); return true; case Keys.Right: GoRight(); return true; case Keys.Left: GoLeft(); return true; case Keys.Down: GoBackward(); return true; case Keys.Space: Beep(); return true; } return base.ProcessCmdKey(ref msg, keyData); } I also use this code to figure out if the user has released perviously presed key: private

How to catch keyboard input with jQuery .keyup() function

问题 Working on a simple hangman game, and I'm trying to catch the user input with the keyup() , but when I log it to the console I'm realizing something isn't working right... this is my code: $(document).keyup(function(e) { userInput = e.value; console.log(userInput); }); I also tried doing this, but it isn't working either. $(document).keyup(function(e) { userInput = $(this).val(); console.log(userInput); }); oh, by the way, userInput is a global variable. 回答1: You have to get the value from

Why is tab keypress causing focus change also triggering keyup event?

由 跟風遠走 提交于 2019-12-08 09:35:16
问题 Pressing the tab key which triggers a focus change is also received by the input receiving the focus as a keyup. a: <input type='text'/><br/> b: <input type='text' onkeyup='alert("wtf?")'/><br/> http://jsfiddle.net/59SnP/ As my control also uses tab (not in the example), I would want the focus related keyup event being consumed ( but I want to receive other non-focus-change related tab events) . I tried to research the rationale behind the current behavior but found nothing. The question:

How to get the key TAB event on an input element?

由 末鹿安然 提交于 2019-12-07 19:09:17
问题 I try to trigger a button when in an input field the return key has been hit. This works. But if I hit the tab key nothing is triggered because the TAB key event isn't captured. Fiddle example Here is my JQ code snippet for example: $("input[name=input]").on("keypress, keydown, keyup", function(e) { var code = e.keyCode || e.which; if ( code == 13 || code == 9 ) { $("input[name=btn]").trigger("click"); } }); I can't figure out how to get the tab key stroke working like a return key stroke.
