Replacing the <img> src with Angular.js

Question

I am currently building a slideshow of header images, then on click select and set that header image to replace the old one. This is my code so far:

var app = angular.module('plunker', []);

app.controller('BannerCtrl', function($scope) {  

  var imageCounter = 0;

  $scope.nextButton = function () {
    imageCounter = imageCounter + 1;
    if (imageCounter === 1) {
      $scope.carouselState = 'second-slide';
    }
    if (imageCounter === 2) {
      $scope.carouselState = 'third-slide';
    }
    if (imageCounter > 2) {
      imageCounter = 0;
      $scope.carouselState = 'reset-slide';
    }
  };

  $scope.previousButton = function () {
    imageCounter = imageCounter - 1;
    if (imageCounter < 0) {
      imageCounter = 2;
      $scope.carouselState = 'third-slide';
    }
    if (imageCounter === 1) {
      $scope.carouselState = 'second-slide';
    }
    if (imageCounter === 0) {
      $scope.carouselState = 'reset-slide';
    }
  };

  $scope.setHeader = function () {
    if (imageCounter === 0) {
      $scope.currentbannerImage = '/styles/img/banner-default1.jpg';
      $scope.bannerState = '';
    }
  };

  $scope.currentbannerImage = [
    {
      src: "1.jpg"
    }
  ];

  $scope.bannerImages = [
    {
      src: "2.jpg"
    },
    {
      src: "3.jpg"
    },
    {
      src: "4.jpg"
    }
  ];
});

I have also set up a Plunker, to demonstrate what I am on about!

Please can someone help me to replace the 'currentBannerImage' with one of the other 'bannerImages'?

Thanks,

JP

You can use AngularJS UI Bootstrap for implementing carousel with AngularJS (if your interest is strictly in solution).

Edit:

I'm not sure if that's what you wanted, but maybe this will be helpful: http://jsfiddle.net/FKUs3/

<img ng-src="{{availableImages[currentImage].src}}"/>

and

$scope.currentImage = 0;
$scope.availableImages = [
{
  src: "http://upload.wikimedia.org/wikipedia/commons/thumb/8/80/US_1.svg/50px-US_1.svg.png"
},
{
  src: "http://0.tqn.com/d/painting/1/0/V/_/1/Stencil-Number2a.jpg"
},
{
  src: "http://eminiunderground.com/wp-content/uploads/2012/02/Stencil-Number3a.jpg"
}
];

$scope.nextButton = function() {
  $scope.currentImage++;
  if ($scope.currentImage > ($scope.availableImages.length - 1)) {
    $scope.currentImage = 0;
  }
}
$scope.prevButton = function() {
  $scope.currentImage--;
  if ($scope.currentImage < 0) {
    $scope.currentImage = ($scope.availableImages.length - 1);
  }
}

Thanks for replying, though I have made a carousel, it is just the image 'src' setting I can't seem to get working.

I'm not sure that's what you wanted, but here it is, in edit of this post :) Hope it will be helpful.

That is a good answer, I will definitely use parts of this, but the main thing is that I need to update the image src. Thanks for your reply.

Actually, the basis of that, with a little gentle nudging, is exactly what I want! Thank you!

I think you can simply change the value of the currentbannerImage on setHeader:

$scope.setHeader = function () {
    $scope.currentbannerImage = $scope.bannerImages[imageCounter];
};

Given that a go, but it doesn't work for me. Tried setting the index of the current image also, but that didn't work! $scope.currentbannerImage[0] = $scope.bannerImages[imageCounter];
