delay

问题 I have made a (rather complicated) solution where I have 4 menu items pop in/out from the side and I make that happen by toggling a class. $('.menuitem').toggleClass('show'); It works great but the client now wants it to "slide out". I figured that I can make him happy if I can create a delay between each toggle, but I cant find a good way to do it. In practice I want each menu item to toggleClass but with a delay of maybe 250ms before next toggleClass. Edited - Apparently the delay function

问题 So I am trying to fix an audio delay problem on web videos. e.g If I go on to youtube and see that the video doesn't match with the audio, I want to postpone or pre-play the audio, so that it syncs with the video. I have figured out how to postpone the audio, but I couldn't figure out how to pre-play the audio. Please help I have tried setting the audio playback rate to be 2.0 and set it back to 1.0 after, so after 1 second, it will sync will the video. But I can't set the playback rate of

问题 I have a dropdown menu that works fine, but I would like it so, that if I hover off the menu, it doesn't immediately hide again. So basically I would like a one second delay. I have read about setTimeout, but not sure if it is what I need? $('#mainnav a').bind('mouseover', function() { $(this).parents('li').children('ul').show(); }); $('#mainnav a').bind('mouseout', function() { $(this).parents('li').children('ul').hide(); }); 回答1: setTimeout is exactly what you need. $('#mainnav a').bind(

问题 I want to make an Activity Indicator start animating and then stop after one second. So does anyone know how I could do that? class stuff { @IBOutlet weak var indicator: UIActivityIndicatorView! func iGotTriggeredBySomething { indicator.startAimating() //delay? indicator.stopAnimating() } } Thanks for answering. 回答1: dispatch_after() is the standard way of delaying actions. indicator.startAnimating() let delay = 4.5 * Double(NSEC_PER_SEC) let time = dispatch_time(DISPATCH_TIME_NOW, Int64

问题 I began studying assembly this year in my school, and we just started learning about pixels. Our teacher gave us some code and told us to mess around with it, he also told us to try and implement delay in the code(ah=86h|int 15h), but when i tried to use it the location and colors of some pixels got changed, and i don't understand why code: (just a piece of the code, there is some more there also get's ruined after the delay) mov cx, 20 add [y], 2 mov dx, [y] paint1RowOf10: mov bh, 0h mov bx,

问题 I have a program in which I utilize a score counter. That score counter is initially 100 and stays like that until a certain threshold is crossed. The threshold variable is called shipy and my score is called score . I implemented something that subtracts 1 from my score every 0.1s once shipy is over 400, but doing it like that causes my whole program to run slower. Here a snippet of my code: shipy = 0 score = 100 # some code here doing something, eg. counting shipy up if shipy > 400: time
