How to use controller as syntax in the following scenario - angularjs

Question

controller as syntax problem
I am a newbie to angular, so please forgive me if i'm wrong. I have a problem where a service is used for certain operation. In this case, adding books to cart.
I have followed the recommended way using controller as syntax instead of $scope. But in kart-list.html, i'm not able to access kart details, since this operation is done by BookListCtrl.
app.js
var app = angular.module("app", ["ngRoute"]);
app.config(function($routeProvider) {
$routeProvider
.when("/books", {
templateUrl: "partials/book-list.html",
controller: "BookListCtrl",
controllerAs: 'booklist'
})
.when("/kart", {
templateUrl: "partials/kart-list.html",
controller: "KartListCtrl",
})
.otherwise({
redirectTo: "/books"
});
});
app.factory("kartService", function() {
var kart = [];
return {
getKart: function() {
return kart;
},
addToKart: function(book) {
kart.push(book);
},
buy: function(book) {
alert("Thanks for buying: ", book.name);
}
};
});
app.factory("bookService", function() {
var books = ['some data'];
return {
getBooks: function() {
return books;
},
addToKart: function(book) {
}
}
});
app.controller("KartListCtrl", function(kartService) {
var self = this;
self.kart = kartService.getKart();
self.buy = function(book) {
kartService.buy(book);
};
});
app.controller("HeaderCtrl", function() {
var self = this;
self.appDetails = {};
self.appDetails.title = "BooKart";
self.appDetails.tagline = "We have collection of 1 Million books";
});
app.controller("BookListCtrl", function(bookService, kartService) {
var self = this;
self.books = bookService.getBooks();
self.addToKart = function(book) {
kartService.addToKart(book);
};
});
book-list.html
<div id="bookListWrapper">
<form role="form">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search here..." />
</div>
</form>
<ul class="list-unstyled">
<li class="book" ng-repeat="book in booklist.books" style="background: white url('imgs/{{book.imgUrl}}') no-repeat">
<div class="book-details clearfix">
<h3>{{book.name}}</h3>
<p>{{book.price}}</p>
<ul class="list-unstyled list-inline">
<li>Rating: {{book.rating}}</li>
<li>Binding: {{book.binding}}</li>
<li>Publisher: {{book.publisher}}</li>
<li>Released: {{book.releaseDate}}</li>
</ul>
<p>{{book.details}}</p>
<button class="btn btn-info pull-right" ng-click="addToKart(book)">Add to Kart</button>
</div>
</li>
</ul>
</div>
kart-view.html
<div id="bookListWrapper">
<p>Please click on buy button to buy the book.</p>
<ul class="list-unstyled">
<li class="book" ng-repeat="book in kart" style="background: white url('imgs/{{book.imgUrl}}') no-repeat">
<div class="book-details clearfix">
<h3>{{book.name}}</h3>
<p>{{book.price}}</p>
<ul class="list-unstyled list-inline">
<li>Rating: {{book.rating}}</li>
<li>Binding: {{book.binding}}</li>
<li>Publisher: {{book.publisher}}</li>
<li>Released: {{book.releaseDate}}</li>
</ul>
<p>{{book.details}}</p>
<button class="btn btn-info pull-right" ng-click="buy(book)">Buy</button>
</div>
</li>
</ul>
</div>
Problem is how use controller as syntax for kart-list.html near ng-repeat to access kart details?

Answer 1

Your'e using the controller as feature but you haven't covered all view references.
book-list.html
<button ... ng-click="addToKart(book)">Add to Kart</button>
Change to
<button ... ng-click="booklist.addToKart(book)">Add to Kart</button>
kart-view.html
<li ... ng-repeat="book in kart" ...
...
<button ... ng-click="buy(book)">Buy</button>
Change to
<li ... ng-repeat="book in KartListCtrl.kart" ...
...
<button ... ng-click="KartListCtrl.buy(book)">Buy</button>

Answer 2

You have to prefix booklist while calling addToKart() method in book-list.html.
Use below file which will resolve your issue:
book-list.html
<div id="bookListWrapper">
<form role="form">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search here..." />
</div>
</form>
<ul class="list-unstyled">
<li class="book" ng-repeat="book in booklist.books" style="background: white url('imgs/{{book.imgUrl}}') no-repeat">
<div class="book-details clearfix">
<h3>{{book.name}}</h3>
<p>{{book.price}}</p>
<ul class="list-unstyled list-inline">
<li>Rating: {{book.rating}}</li>
<li>Binding: {{book.binding}}</li>
<li>Publisher: {{book.publisher}}</li>
<li>Released: {{book.releaseDate}}</li>
</ul>
<p>{{book.details}}</p>
<button class="btn btn-info pull-right" ng-click="booklist.addToKart(book)">Add to Kart</button>
</div>
</li>
</ul>
</div>
