Clash Royale CLAN TAG #URR8PPP AngularJS compare two (scope) arrays and only POST the 'non-same' result (2018) I have two arrays that i like to compare on the ID, if the ID from one array does not exist in the other i will add it with the Http Post. This is the build up: $scope.Games = [{id:1,Name:"BatMan"}, {id:2,Name:"SpiderMan"}, {id:2,Name:"Hulk"}]; $scope.NewGames = [{id:1,Name:"BatMan"}, {id:2,Name:"SpiderMan"}, {id:3,Name:"Hulk"}, {id:4,Name:"DeadPool"}, {id:5,Name:"IronMan"}, , {id:6,Name:"DrStrange"}]; so i load all the Games and NewGames with a GET in the two $scopes Now i would like to compare the two on the id_game, so i was thinking of something like this but can't get it to work, the http section works find however without the indexOf, it will add...

Clash Royale CLAN TAG #URR8PPP console.log(this) in global scope returns undefined I have created a script which logs the this variable to the console in the global scope. If I launch the script in the browser it returns undefined. eg. console.log(this); //returns undefined However if I enter the same command directly in the browser console it returns the window object. Which is what I was expecting. eg. console.log(this); //returns Window {postMessage: ƒ, blur: ƒ, focus: ƒ, close: ƒ, frames: Window, …} console.log(this); //returns Window {postMessage: ƒ, blur: ƒ, focus: ƒ, close: ƒ, frames: Window, …} Why is the behavior/output of logging 'this' to the console different in the browser console and different while expecting the output from a script?

Clash Royale CLAN TAG #URR8PPP How can you increment a number on scroll without having the scrollbar(actually scrolling)? So, imagine 2 sections/divs (both with width: 100% and height: 100% ). I only see the first section, the second section is to the right side of the screen, unable to be seen(overflow: hidden; on the body). width: 100% height: 100% Now, when I scroll, I want that second section to appear gradually, with each pixel I'm "scrolling". But, the problem here is, I can't actually scroll, thus properties such as this: window.pageYOffset , element.getBoundingClientRect() do not work. Basically, I want to increment a number each time I do a scrolling gesture, so I can assign that number to the second section( to modify its left property so it can come in the viewport ). And I don't know how to increment the number. window.pageYOffset element.getBoundingClientRect() This is a recreation of what I'm trying to accomplish: var secondSection = document.g...
