timer

问题 A timer to fire an AJAX call if no key is pressed. If a key is pressed, then abort the last timer and add a new timer. That is what I want to do but failed to success. Here is my code: var t; input.onkeyup = function(){ $('.confirmText').html('Checking...'); var timeStampObj = new Date() var timeStamp = timeStampObj.getTime(); var oldTimeStamp = $(this).attr('timeStamp');//I store a timeStamp in the element if(timeStamp < 500 + oldTimeStamp){ $(this).attr('timeStamp', timeStamp); clearTimeout

问题 I tried making a game loop in Java using the Timer from java.util.Timer. I am unable to get my game loop to execute during the timer tick. Here is an example of this issue. I am trying to move the button during the game loop, but it is not moving on the timer tick event. import java.util.Timer; import java.util.TimerTask; import javax.swing.JFrame; import javax.swing.JButton; public class Window extends JFrame { private static final long serialVersionUID = -2545695383117923190L; private

问题 I need a function(eg signal handler) in C/C++ linux that gets activated every 'n' milliseconds. How do I setup signals etc...to register to timer events at the millisecond resolution. Accuracy is not super critical, but need within hundred ms or so. I am new to linux and I really don't know where to start. 回答1: setitimer(2) is a good start, but do you really want to go asynchronous with signals? Otherwise, you could have a main loop with select(2) or poll(2) and an appropiate timeout. 回答2: A

问题 Original post: How to access a timer from another class in C# I tried everything. -Event -Invoke can't be done,because Timers don't have InvokeRequired property. -Public/internal property Nothing worked,the code is being executed,the timer.Enabled property is being set to "true" ,but it doesn't Tick.If I call the event or just change the property from the form class in a NON-static method - it does tick and works. I never knew it would take me a day and probably more to acquire how to use a

问题 I'm new to swing, any help appreciated. In this piece of code I'm turning a card over face up, if it turns out that they don't match I want them to turn back face down again. At the moment what is happening: 1. when clicked the first card turns over 2. when a second card is clicked either of two things happen (a) if they are the same they both stay up which is what I want (b) if they are not the same I never see the 2nd card at all as it immediately re-displays the back of the card (and the

问题 I need an actor to send a message every minute. How do I best achieve this behaviour? I am afraid of using java.lang.Thread.sleep(long millis) as a thread can be shared among many actors in Scala, as far as I understand. 回答1: Create an actor with receiveWithin to act as the timer. 回答2: Or as @Daniel mentioned, here a running example: import scala.actors._ import scala.actors.Actor._ class TimerActor(val timeout: Long,val who: Actor,val reply: Any) extends Actor { def act { loop { reactWithin

问题 We're getting following problem while using System.Threading.Timer (.NET 2.0) from a Windows service. There are around 12 different timer objects.. Each timer has due time and interval. This is set correctly. It is observed that after 3 to 4 hours, the timers start signaling before their interval elapses. For example if the timer is supposed to signal at 4:59:59, it gets signaled at 4:59:52, 7 seconds earlier. Can someone tell me what is the cause for this behavior and what is the solution

问题 I need to make a page that has a timer counting down. I want the timer to be server side, meaning that when ever a user opens the page the counter will always be at the same time for all users. When the timer hits zero I need to be able to run another script, that does some stuff along with resetting the timer. How would I be able to make something like this with php? 回答1: Judging from "when ever a user opens the page" there should not be an auto-update mechanism of the page? If this is not

问题 Im trying to animate 2 boxes to go from the top right to the bottom left of a JPanel. For the animation I'm using a Swing Timer and SwingUtilities.invokeLater() . The problem is that when I click the start button. It only animates and moves the blue box, but not the red one. Heres the code: //import neccessary stuff public class Example extends JFrame { public static void main(String[] args) { Example e = new Example(); e.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); e.setSize(600, 565); e
