kandi X-RAY | slideo Summary
This tool matches video frames against PDF pages by using computer vision. It also ships a web app in which you can click on a PDF page to play the video from the first frame showing the page. Its primary use-case is to quickly play a recorded lecture from a given slide. Works best if the PDF page in the video is captured through screen recording and video is 1080p, but it might work in other scenarios too (rotation, shifting, scaling, obstruction and additional on-screen content is supported).

QUESTION
I was working on a personal project of making a slider using pure javascript. But The js code is not working. When I click the next button, the console shows an error that next() is not a function. Same with the Previous button it says prev() is not defined. I tried everything I could but I am not able to find the answer. It is confusing that I have declared both the functions but on click, I receive an error that functions are not functions.
main.js:38 Uncaught TypeError: next is not a function at HTMLElement. (main.js:38)
JS Code:

QUESTION
I am currently trying to add a button so that I can go to a different page in a UIScrollView but I keep getting the error. Basically I'm creating custom slides that take up about a third of the bottom of the screen with the scrollview.
[App.ViewController aButton:]: unrecognized selector sent to instance 0x7fe464c131c0 2017-07-19 22:47:48.791 App[10680:546634] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[App.ViewController aButton:]: unrecognized selector sent to instance 0x7fe464c131c0'
so far I've read a few posts on here and have tried
pagecontrol.currentpage = 0
and
...mainScrollView.contentOffset = CGPoint(x: mainScrollView.frame.size.width*1, y: 0)

which means you have a method that does not implement at a certain controller.
And reason: '-[App.ViewController aButton:]: unrecognized selector sent to instance 0x7fe464c131c0'
which means the method of aButton:
in App.ViewController
does not implement or you call App.ViewController
does not contain this method
