I'm very new to JavaScript and currently using JSX to design a website. I am hoping to add an infinite scroll component where the user scrolls to the bottom of a list of, say, 5 images, and then 5 more load, etc.
I have built my own rest API server and plan to implement my JS such that upon each user scroll to the bottom, it will call on this API to load the data for another 5 images; however, I am lost on how to best handle this scroll event by the user.
I am trying to find a tool/component that would help me implement this scroll that is already embedded in the standard React library. It is important that this is not something I have to install outside of the React library. I have read through tons of React documentation and S.O. posts, but have been unable to find one- could someone point me in the right direction?
This one should do the work
react-infinite
Or native

I was re-creating the animation shown in Stripe website. Where a set of div's move together and it repeats infinitely.
I was trying to reproduce the same in my react app. But I'm stuck at how to implement the animation in it.
In This tutorial they are doing the animation , but i could not find a way to implement the two classes in the js file in the above tutorial in my application.
Please tell me a solution to implement the animation, with or without the use of external react animation libraries.

I would like some guidance on how to create an action-sheet/bottom-sheet style drawer in React-Native so that I could use a single code base for both iOS and Android.
I've attempted to use the Animated Spring API. However, I'm not able to change to location of the Spring from the original location (while the drawer is closed), to the top location (while it is open). So that if the user doesn't complete the gesture, the menu goes back to its original location in either state, instead of the original position at the bottom.
Furthermore, many of the other answers to similar questions all recommend using their own or some other package on GitHub/NPM.
I'd like to make my own to keep dependencies small. I've also considered using React-Navigation but I can't seem to find anything that fits my use-case.
react-native-action-sheet is great if you're looking to get as close as possible to the native versions of Action Sheets.

I have been trying to develop a very basic game using Ionic. Initially, I was using pure JavaScript to listen to clicks and then act on them but the response time was very long. When I asked a question on Stack overflow, it was suggested that I should be using Angular JS to work optimally with Ionic apps. Now, I have started using Ionic but the response time is still very very slow.
I am using ng-mousedown and ng-mouseup to detect mouse down and mouse up events. The buttons are positioned absolutely over a canvas element which occupies all the screen space. A single tap on any of the buttons results in no response. I have to keep the button pressed for some time before the logic kicks in. There is no such lag on my PC. Can anyone please guide me on how can I improve the response time?
Let me know if I need to add any code here but it doesn't seem to be a problem with the code because there is no such issue on PC.
Try this...It should solve your problem..Actually the ionic.js is sometimes responsible for delays Ionic handle delay
Eventually, their may be a system performance related issue.If, other apps are lagging behind.
Need to implement a feature where auto suggest shows first 10 result, when user scrolls it fetches further 10 from server.
I have implemented auto suggest using rich faces <rich:suggestionbox> but it does not support paging or infinite scroll.
It would be great if someone can guide me with some JSF based component or way of customizing the existing suggestion box.
Web app here:

Main javascript here:
http://www.digitaltransitions.com/visualizer/visualizer.js
Relevant functions are at bottom of visualizer.js, named "dragger" "move" and "up".
I was a programmer a decade ago, and recently took it back up to help my company create a web app that helps our customers visualize how a specific lens will look on a specific camera.
Never mind the info wall (info request form); feel free to put in any garbage entries. Or you can add the function unlock(); at the end of the window.onload and it will bypass the info wall screen and go straight into the app.
I've been very proud to get this far. But now I am majorly stuck and have been banging my head against the wall.
My web app passed testing on Mac_Safari, Mac_Chrome, Mac_Firefox. But it failed testing on an iPhone4s and iPad1; the sliders for focal length (the ##mm gizmo in the top right which changes how "zoomed" the lens is) do not function correctly. When the user grabs the slider some of the time it correctly slides back and forth, but other times it will jump to the far left of the screen at which point the app stops working at all.
Any thoughts would be greatly appreciated!!
By the way, if you were wondering how to create a custom Google Docs Form with validation and a custom confirmation page I got my methodology from here:

I'd say your first job is to determine if this your bug, or Raphael's bug. I'd start by switching out your "move" method with an empty method, and see what happens.
Another debugging approach would be to put a fixed-position div down in the corner of the page, and spit the x/y values into it, so you can see in real-time what the numbers look like.
I'd guess that you're running into a mathematical difference in how touch-points are calculated vs. how mouse-cursor-position is calculated.
Based on the hack you added, it looks like Raphael might be sending you a NaN value for Dx?
