What is the best way to iterate through data within a view while showcasing information retrieved using AngularJS?

As I start my journey into learning AngularJS, I am looking for some guidance from those who have experience with it. Although I am proficient in JavaScript/jQuery, I am finding it challenging to grasp the fundamentals of AngularJS at the moment.

My query involves a table that will be used to display "users" fetched through a GET request.

Each "user in users" will follow a schema resembling: {name:'', rating:4, reviews:10}

The "rating" field is an integer ranging from 1 to 5, where each number corresponds to a star (out of 5 possible stars). My goal is to create an IMG tag for each rating value that displays a single star.

This is a snippet of what I have:

<tbody>
    <tr ng-repeat="user in users">
        <td>{{user.name}}</td>
        <td>
            <img src="star.jpg" ng-repeat="n in [].constructor(user.rating) track by $index">
        </td>
        <td>{{user.reviews}}</td>
    </tr>
</tbody>

I am struggling with setting up this loop correctly. The current implementation doesn't work as intended. My aim is to utilize {{user.rating}} to dictate the number of stars to display.

Your insights and assistance would be greatly appreciated.

Answer №1

To utilize ng-repeat in this scenario, one option is to establish a function within the scope that generates an array of n elements:

$scope.starRating = function(rating) {
    var stars = [];
    for (var i = 0; i < rating; i++) {
         stars.push(i);
    }
    return stars;
}

Then, within the view, you can implement the following:

ng-repeat="star in starRating(user.rating)"

Alternatively, it's possible to create a custom directive specifically designed to iterate and display content N times.
