How do I go about this ? I would like to display the animations with a linearly increasing delay based on the index of the item. Currently, if I use 2 buttons, 'add' and 'remove', and then do the respective operations on the recyclerview ( notifyItemInserted() and notifyItemRemoved() , the animations come in nicely.

How to use FastClick.js with Phonegap and JQM?

阅读更多关于 How to use FastClick.js with Phonegap and JQM?

I've tried a few different ways to remove the 300ms delay due to the webkit browsers handling of touch events. The library, FastClick.js, seems to be the preferred method, yet I'm having a little trouble implementing it. I've included it and also added an event listener, but I don't know if I've added the listener correctly. Should this be working or am I failing to do something? Thank you! Consider the code below, where <!DOCTYPE html> <html> <head> <title> Calculator </title> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum- scale=1.0, user-scalable=no;"> <meta

I have this code, which slides open a basket preview on a website I am working on. It stays open if the user is hovered on it, but I want it to have a two second delay before the callback for my hover is triggered. This is just in case the user didn't want the mouse to leave the basket area. Below is the code I am using to animate the basket: $('.cart_button, .cart_module').hover(function(){ $(".cart_module").stop().animate({top:'39px'},{duration:500}); }, function(){ $('.cart_module').stop().animate({top: -cartHeight},{duration:500}) }); Here is the code I tried to use, but had no affect: $('

阅读更多关于 How Can I Open a WPF Popup with a Delay?

I simply want to open up the WPF Popup with a delay, sort of like a ToolTip . How can I achieve this? And, by the way, Popup.PopupAnimation = PopupAnimation.Fade ... fades in too quickly. I want at least half a second in there. You can create a style to be applied to the Popup in the following way: <Style x:Key="TooltipPopupStyle" TargetType="Popup"> <Style.Triggers> <DataTrigger Binding="{Binding PlacementTarget.IsMouseOver, RelativeSource={RelativeSource Self}}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard x:Name="OpenPopupStoryBoard" > <Storyboard>

I have some jquery and am trying to apply a delay to it but can't seem to get it to work. The current jquery is as follows... image.css({"visibility" : "hidden"}).removeClass("image-background"); and I have tried ammending this according to the jquery website (http://api.jquery.com/delay/) to apply the delay... image.delay(800).css({"visibility" : "hidden"}).removeClass("image-background"); but this doesn't seem to make any difference.

I need a transition page that will display for 2 seconds before automatically redirecting to the home page. How do I do this? I can't seem to get delay to work for me.

I would like to create a delay function in javascript that takes a parameter of amount of time to delay, so that I could use it do introduce delay between execution of javascript lines in my QML application.

问题 I'm using the following code (written by another user) to throttle ajax requests in a livesearch function: JSFiddle if you prefer a demo: http://jsfiddle.net/4xLVp/ It seems buggy, though. Clearing values with Ctrl+shift+back-arrow , and typing again causes a flurry of requests. Blank values also cause a request. It dones't seem right, especially compared to jQuery UI autocomplete, where request delays seem more measured. $('##tag-search').keyup(function() { var elem = $(this); if (elem.val()
