timer

问题 Here is a jQuery slide function I have applied to a div on hover in order to slide a button down. It works fine except that now everytime someone moves in and out of it, it keeps bobbing up and down. I figured if I put a one or two second delay timer on it it would make more sense. How would I modify the function to run the slide down only if the user is on the div for over a second or two? <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js "></script> <script

问题 Consider the following code : class TestTimerGC : Form { public TestTimerGC() { Button btnGC = new Button(); btnGC.Text = "GC"; btnGC.Click += (sender, e) => GC.Collect(); this.Controls.Add(btnGC); System.Windows.Forms.Timer tmr = new System.Windows.Forms.Timer(); tmr.Interval = 1000; tmr.Tick += (sender, e) => this.Text = DateTime.Now.ToString(); tmr.Start(); } } If I'm not mistaken, after the tmr variable goes out of scope, the Timer isn't referenced anywhere, so it should be eligible for

问题 I'd like to have a java.utils.Timer with a resettable time in java.I need to set a once off event to occur in X seconds. If nothing happens in between the time the timer was created and X seconds, then the event occurs as normal. If, however, before X seconds has elapsed, I decide that the event should occur after Y seconds instead, then I want to be able to tell the timer to reset its time so that the event occurs in Y seconds. E.g. the timer should be able to do something like: Timer timer

问题 I have a jsfiddle here - http://jsfiddle.net/5z2vu47a/ It's a simple timer that should change text that taken from and array The timer only works once. Why does the timer not continue to work. var name_arr = ['learn', 'product', 'buying', 'selling', 'marketing', 'managing', ]; var counter = 0; function names(){ alert(counter); $('.text p').text(name_arr[counter]); counter++; alert(counter); } setTimeout(names, 1000); 回答1: You need to use setInterval setInterval(names, 1000); In the names

问题 I have an application with the following code in my main function: var timer = new System.Threading.Timer(Callback_f, null, TimeSpan.Zero, TimeSpan.FromMinutes(srcInterval)); Okay this actually works but ONLY when I put something to keep my application alive like console.readkey() or an infinite while loop: while (true) { }. The infinite loop is not an option for me as it is too time consuming. The thing is I can not use the console.readkey function either because it's a Windows.forms

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . This isn't working the way I expected. However, the way I expect it to work is probably wrong. I have an application that implements a Countdown timer. When the back button on the android phone is clicked the

问题 I'm writing a simple pikachu game in Java, and I use swing.Timer with JProgress Bar, my code is like this: public static void TimeBarListener(final View scr){ ActionListener updateProBar = new ActionListener() { @Override public void actionPerformed(ActionEvent actionEvent) { int val = scr.timeBar.getValue(); if (val <= 0) { scr.gameOver(); scr.timer = null; return; } scr.timeBar.setValue(--val); } }; int t = n*400; scr.timer = new Timer(t, updateProBar); } The "src" here is a class which

问题 I solved the problem. var backgroundUpdateTask: UIBackgroundTaskIdentifier = 0 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { return true } func applicationWillResignActive(application: UIApplication) { self.backgroundUpdateTask = UIApplication.sharedApplication().beginBackgroundTaskWithExpirationHandler({ self.endBackgroundUpdateTask() }) } func endBackgroundUpdateTask() { UIApplication.sharedApplication()

问题 I do not understand how to utilize the timers in vb.net I want to make a simple program where when I press a button the timer starts and the label changes it's number every second until 60 seconds have passed. I think I should put this in the button event Timer1.Start() But I am unsure of what to do from there. How do I go about doing this? 回答1: Well Timer1.Start() starts the timer, but you need to declare how often the timer ticks. Timer1.Interval = 1000 will make the timer tick every 1000
