Question

How can I iterate through a variable length using AngularJS templates?

I'm currently working on a project where the car.images_length variable holds a specific number, let's say it's "4". My goal is to iterate through this variable and create 4 <li> elements based on its value.

Through logging with JavaScript, I already verified that the car.images_length variable is indeed populated with a value.

Although this may seem like a beginner question, I'm relatively new to AngularJS.

I made an attempt at solving this issue, but unfortunately, I haven't been successful. Below is the code snippet I've been working on:

The HTML

<ul rn-carousel rn-carousel-buffered class="image" ng-repeat="pics in car.images_length">
    <li><img src="images/cars/{{$index}}.jpg"></li>
</ul>

javascript angularjs

Answer №1

To properly iterate over the li elements, make sure you are targeting the li elements, not the ul elements.

<ul rn-carousel rn-carousel-buffered class="image" >
     <li ng-repeat="number in range(0, car.images_length)"><img src="images/cars/{{number}}.jpg"></li>
</ul>

The ng-repeat directive requires an array, not a single value. Therefore, you need to create an array. In the example above, I created a range from 0 to the length of the images.

In your controller, you will need to define the range function:

$scope.range = function(min, max){
    var result = [];
    for (var i = min; i <= max; i++) result.push(i);
    return result;
};
