问题 How can I get my images to appear one after the other? I am currently using Jquery fadein to make my images fadein but I want them to start at different times. Is there anyway i can delay an image from fading in? in seconds? <script type="text/javascript"> $(document).ready(function(){ window.onload = function() { $('.fader1').hide().fadeIn(3000); $('.fader2').hide().fadeIn(9000); $('.fader3').hide().fadeIn(6000); }; }); </script> <div class="fader1"><img src="demo.jpg"></div> <div class=

问题 I am creating an app where a timer is set by the user. When the app goes to the background, the timer.invalidate() . Now I want the timer to start again when the app comes back to the foreground. I am creating another instance of timer to do it when the app sends notification that app is in the foreground. However, it's not firing the function. In Viewdidload() I am creating a timer: timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(handleCountdown), userInfo:

问题 With the help of an online tutorial, I created a simple 60 second countdown timer. I'd really like the text color to change to red once the timer hits 10 seconds. Any clue how I can add to this AS to make that happen? Bonus question: when the timer hits zero, I'd love for the entire text field to fade out so that the zero isn't visible anymore. Any thoughts on that? Here's my code, and thank you!!! var nCount:Number = 60; var myTimer:Timer = new Timer(1000, nCount); timer_txt.text = nCount

问题 I have a Universal/Portable C# library for Windows Phone 8 and Windows 8. The library will be referenced by apps for each platform. In the library is a view model and I'm trying to put a timer in the view model. The only "Timer" available in the library for both platforms is the System.Threading.Timer (no DispatcherTimer). However, I cannot work around the cross threading issues. Is there a way to do this or do I have to create a timer in each app in the page code behind? public class

问题 So I have a label that counts 1 every second using an NSTimer . I made an app that has a few moving UIImage s. However every time the timer counts one up, the view seemingly reloads and the UIImage s go back to their original positions. Furthermore, the UIImage s are not where I had placed them in the storyboard (I placed them outside the view so they could move inwards, but when I start the app it just shows them right there already. They move but only for one second then go back to their

问题 I need to add an NSTimer in the applicationDidEnterBackground method; I tried adding NSTimer.scheduledTimerWithTimeInterval(5, target: self, selector: Selector("test"), userInfo: nil, repeats: true) But it's not working. 回答1: According to your comments, your declaration should look something like this: NSTimer.scheduledTimerWithTimeInterval(60, target: self, selector: "test:", userInfo: nil, repeats: false) Note two things: You can pass a string literal to the selector parameter directly (no

问题 I created an MFC dialog based app and wanted to add timer on the form. But it turns out that MFC is different than the .NET windows forms. I added the ON_WM_TIMER() in the messagemap. and added the function definition for CMyDialog::OnTimer(UINT_PTR x) { } But I am getting a compiler error in VS2005. I do not know what i am doing wrong. "error C2509: 'OnTimer' : member function not declared in 'CMyDialog'" Help is greatly appreciated. Thanks. 回答1: Obviously, you forgot to declare the function

问题 I'm doing a packet injection with scapy and creating a threading.Timer which deletes the packet information from the dictionary after 10 seconds. If I receive a response before 10 seconds, I'm cancelling the Timer and deleting the packet information from the dictionary. Since I'm cancelling the Timer, I can put .join() here. But when the Timer expires, there's no mechanism to .join() . When I run the program, the memory keeps on increasing. No doubt, increasing is slow (Initially 2% in a 1 GB
