I’m beginning with Angular and I saw this example in this page http://tutorialzine.com/2013/08/learn-angularjs-5-examples/ and I’m trying to reproduce some of them.
The example 4 looks like something I can use right away in the system I’m working on right now.
I couldn’t get it to work integrated on my system, so I isolated the example in a single file and I’m getting the exact same result as in my system.
The console gives the the following error:
angular.js:13236Error: [ng:areq] http://errors.angularjs.org/1.5.0/ng/areq?p0=InstantSearchController&p1=not%20a%20function%2C%20got%20undefined

I’m trying to figure out why it says InstantSearchController is not a function, it should be working since it’s a copy and paste from a working example from the web.
I was thinking things should be declared in a certain order but even moving things around in the page didn’t give me any result.
Maybe the working example and the code being shown are different.

This is because your InstantSearchController is not registered in angular application. You should do it like this
Also it is not good idea to bootstrap your application on same element as controller (Either via
ng-app
attribute or programatically). Application should be “global” and inside of the app there should be controllersInstantSearchController
isn’t being defined as a controller. Instead of just creating a function named that, it should be done like this:app.controller('InstantSearchController', function($scope) { ... });
