What is the best way to showcase a singular item from response.data?

Below is the controller I have set up to display details of a single book from my collection of json records

.controller('BookDetailsController', ['$scope','$http','$stateParams',function($scope,$http,$stateParams){
        $http({
            url: "/api/books/",
            method: "get",
            params: {id: $stateParams.id}
        }).then(function(response){
            $scope.books = response.data;
            console.log($scope.books);

        })
}]);

<div class="panel panel-default">
    <div class="panel-heading">Online Bookstore</div>
    <div class="panel-body">
    <div class="col-md-12">
        <div class="col-md-3">
        <img src="{{book.imgUrl}}" class="img-thumbnail" width="200" height="200">
        </div>
        <div class="col-md-9">
            <h2>{{book.title}}</h2>
            <p style="text-align:justify;">{{book.description}}</p>
        </div>
    </div>
    <hr>
    </div>
  </div>

What is the best way to showcase a single book's information retrieved from response.data using the provided controller?

Answer №1

When $scope.books is an array, there are a couple of ways you can interact with the data:

1) Iterate over the entire array to showcase all books

<div ng-repeat="b in books">
    {{b.title}}
    <img ng-src="{{b.imgUrl}}"
    ...
</div> 

2) Display just one book from its specific index in the array

<h1>First book</h1>
{{books[0].title}}
<img ng-src="{{books[0].imgUrl}}"/>

Answer №2

Grab the initial item from the dataset,

$scope.book = response.data[0];

Answer №3

Iterate over the books listed in the primary <div>:

....
<div class="col-md-12" ng-repeat="book in books">
....

To showcase a specific entry (such as index 0), simply refer to books[0] within the view:

  ..
  <img src="{{books[0].imgUrl}}" class="img-thumbnail" width="200" height="200">
</div>
<div class="col-md-9">
  <h2>{{books[0].title}}</h2>
  <p style="text-align:justify;">{{books[0].description}}</p>
</div>

Answer №4

If the variable $scope.books contains an array, you can implement the ng-repeat feature as demonstrated in the code snippet shared by @mistails. This will dynamically generate a list of books, allowing users to select a specific book and retrieve its complete information.

<div ng-repeat="b in books" data-ng-click="showBookData(b)">
    {{b.title}}
    <img ng-src="{{b.imgUrl}}"
    ...
</div>
The showBookData() function can be used to display all the details of the selected book in a modal upon clicking on it.
