问题 I have a list with items. When I click any of these items, I copy its id -value into a form text -field. Everytime I click, it replaces the value, which is correct by default. But what I would like to add, is a way for the user to hold down a key on their keyboard, and when they then click, they just .append whatever they just clicked into the same form field. Here's my jQuery-code I'm using for the first/default scenario: $(function(){ $('ul#filter-results li').click(function(){ var from = $

问题 How do I know whether a certain key on the keyboard is pressed/down or unpressed/up on Mac? Right now I need it for the spacebar, but an answer that would work for any key would be perfect. I don't want to detect the events: -(void)keyDown:(NSEvent*)event; -(void)keyUp:(NSEvent*)event; I want the state of a key (spacebar) at a certain moment. On Windows this seems possible (although I haven't tried it out) with the following code: GetAsyncKeyState(VK_SPACE); But I haven't found a solution for

问题 Why after I press the directional arrow ON, the function GetKeyState continues to give me a value greater than 0? #include <iostream> #include <windows.h> using namespace std; int main() { for(int i = 0; i < 1000; ++i) { if(GetKeyState(VK_UP)) { cout << "UP pressed" << endl; } else cout << "UP not pressed" << endl; Sleep(150); } return 0; } 回答1: From the documentation: The key status returned from this function changes as a thread reads key messages from its message queue. The status does not

问题 I'd like to find out the easiest way how to read Fn key from my keyboard in Python (Windows).I've tried to use Pygame library, but it didn't work for Fn key. 回答1: The "Fn" key is usually a proprietary, device-specific modifier that is handled by the device driver (or the hardware itself). It's not a normal button, and you can't catch it in your code. To be honest, I can't imagine why you'd ever possibly want to. 来源： https://stackoverflow.com/questions/7713539/reading-fn-key
