delay

问题 I have something like this I/global ( 3622): Loaded time zone names for en in 355ms. I/global ( 3622): Loaded time zone names for en in 307ms. I/global ( 3622): Loaded time zone names for en in 309ms. I/global ( 3622): Loaded time zone names for en in 310ms. I/global ( 3622): Loaded time zone names for en in 324ms. and I do not have any idea where this log comes from. I was doing some research on this topic and I guess it comes from new Date(); but I am not sure. I need advice what should I

问题 I have three threads: the main thread and two timers. The first timer activates the second one after a period of time and then disables itself. I use "Thread.Sleep(int)" in order to delay the activation of the second timer. But the whole program pauses when the "Sleep" function is working. How can I pause a thread without pausing the whole program? 回答1: Timers don't execute your code in new threads. After their interval they raise an event in the Windows Message Queue that the main thread

问题 In PyCharm (JetBrains), I have been having trouble with typing full statements without getting an interuption. I first thought it was due to me not having updated the software, so I updated it, but the problem remains. So if I type any statement or word, PyCharm seems to delay before I can proceed. An example: import csv Even before I finish typing "import" - if I delay a keystroke - PyCharm begins to "think" and the window is not accessible for about one to two seconds (quite literally). I

问题 Header $(document).ready(function() { $('#user_box').animate({width: "263px"}, "slow"); $('#submit').click(function(){ $('#user_box').animate({width: "0px"}, "slow"); }); }); Content <div id="user_box"> <form name="login_form" id="login_form" method="post" action="index.php"> Username:<br /> <input type="text" name="username"><br /> <input type="submit" value="Submit" id="submit" /> </form> </div> As you can see, I've made it do when submit is clicked, the user_box animates back to 0pxs

问题 When I run PHP in the CLI mode (PHP 5.6.6 under CentOS 6.5 running as VM using VirtualBox) it has a few seconds of delay even if I only check version and there is php.ini file disabled: time php -n -v PHP 5.6.6 (cli) (built: Apr 2 2015 14:18:24) Copyright (c) 1997-2015 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies real 0m5.066s user 0m0.012s sys 0m0.006s 回答1: The problem is related to DNS call PHP is doing.

问题 I want to pause 1 second for every time it loops, it is usually easy to do similar pauses on other cases, but when working with loops, it seems it get harder: for (var i=0 ; i < 10 ; i++) { document.write (i + "<br>"); // I want to wait 1 second here } This is one example of my thousands failed attempts: function writeMsg (index) { document.write (index + "<br>"); } for (var i=0 ; i < 10 ; i++) { setTimeout (writeMsg(i), 1000); } Any ideas of how to get this to work? 回答1: This function works

问题 I have a situation where it makes more sense to me to have a delay between periodic actions wait for an amount of time in the real world to pass rather than waiting for the system clock to tick some number of times. This way I could, say, renew a lease being tracked on a different system/being timed out in real time after some amount of real time passes. I suspected that Task.Delay might already have this behavior, but I wanted to make sure, so I wrote a test program (see below). My discovery

问题 I've stumpled on something quite nice, I've wanted to use in some upcoming project. It's an animated opacity on load, or you can call it fade in. I wondered if you could link some elements together (ex. 3) so element2 only starts when element1 is finished, and element3 when no. 2 is? Or should you define a delay on element2 and multiply the delay on element3 ? 回答1: If you had divs, say class="faded" , you could fade each in on load, each in a row like this: $(".faded").each(function(i) { $

问题 Trying to get a label with class price to slide up, then slide back down with CSS. I have the following -- -webkit-animation-name: slidingPrice; -webkit-animation-duration: 300ms; -webkit-animation-iteration-count: infinite; -webkit-animation-timing-function: ease-in-out; -webkit-animation-delay: 4s; @-webkit-keyframes slidingPrice { 0% { opacity: 0; bottom: -30px; } 50% { opacity: 1; bottom: 0; } 100% { opacity: 0; bottom: -30px; } } I am seeing that the animation starts in 4 seconds, but

问题 I have a problem with the sleep function in Swift code. I'm using import Darwin and usleep(400000) . Some actions before reaching the sleep are blocked and I dont know why. Here a short example from my code: @IBAction func Antwort4Button(_ sender: Any) { if (richtigeAntwort == "4"){ Antwort4.backgroundColor = UIColor.green Ende.text = "Richtig!" NaechsteFrage() } else { Ende.text = "Falsch!" //NaechsteFrage() } } func NaechsteFrage() { usleep(400000) Antwort1.backgroundColor = UIColor.red
