"I am seeking assistance with AngularJs as I am encountering difficulty selecting an array within an object passed to

Seeking guidance on the issue I'm facing. Is it feasible to interpolate the image array in this manner? The inkObject.header property interpolates properly onto the page, but the array containing a variety of images seems to be causing some trouble...I am uncertain whether passing an array like this within the object is not allowed or if I have made a mistake somewhere.

Appreciate any help.

//Controller in app.js 
app.controller('galleryCtrl', ['$scope', '$http','$location',
       function ($scope, $http, $location) {
           $scope.ink = {
                header: "Personalized Ink Products",
                imageArray:  [

                'ink-1.jpg', 
                'ink-2.jpg',  
                'ink-3.jpg',
                'ink-4.jpg'
                ]

       };
}]); 

//my directive in app.js
app.directive('pictureGallery', function () {
    return {
        templateUrl: 'directives/picturegallery.html',
        replace: true,
        scope: {
            inkObject: '='

            }
    }

});

//the template

<div class="top-space">
    <h1>{{ inkObject.header }}</h1>
    <div class="row">
        <div class="col-xs-6 col-sm-4 col-md-4" ng-repeat="image in {{ inkObject.imageArray }}">
            <a href="img/{{image}}" target="_blank">
            <img ng-src="img/{{image}}"  width="200px" height="200px" 
            class="img-responsive img-thumbnail bottom-space"> 
            </a>  
        </div>
    </div>
</div>

//the view
<picture-gallery  ink-object="ink"> </picture-gallery>

Answer №1

Make sure to follow this guideline:

return {
    ....
    restrict : 'E',  // Element name directive
    ....
}

The default value is 'A' (Attribute).

When using ng-repeat in the template, remember to

< ...   ng-repeat="item in object.itemArray" ...>

Avoid using unnecessary {{ }} brackets.

Answer №2

It seems like the problem lies in the ng-repeat section. You can take a look at this plnkr example for reference: http://plnkr.co/edit/abc123XYZ?referrer=345

What I did was

ng-repeat="item in {{ data.items }}"

I simply changed it to

ng-repeat="item in data.items"

and that seemed to fix the issue.

Answer №3

I discovered that following the advice of both commenters was the key to solving my issue. I needed to remove the brackets, meaning {{inkObject.imageArray}} should simply be inkObject.imageArray. Initially, when I attempted this suggestion, it didn't immediately work as expected. The reason became clear to me shortly after - my browser was caching the data from the directive, causing any edits I made to go unnoticed on screen. This is a common occurrence with directives in AngularJs, so it's something to keep in mind. To overcome this obstacle, I added a query string to the end of the templateUrl which allowed me to see the changes I was making in real time. It turned out that removing the brackets was all that was needed.
