Is there a way to show stars for each item in a list using the 5-star scoring system on a video interface without creating an array for the score?
interface Video{
Score: number;
}
<td>
<span data-bind="foreach: score">
<span class="glyphicon-star"></span>
</span>
<span data-bind="foreach: 5 - score">
<span class="glyphicon-star-empty"></span>
</span>
</td>
If you want to convert the score into an array, you have two options. You can either utilize Array.from(), or simply use Array(score).
Array.from({ length: score })
or
[...Array(score)]
(In case of an observable, use score())
Below is a concise demonstration:
const model = {
score: 3
}
ko.applyBindings(model)<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.2/knockout-min.js"></script>
<span data-bind="foreach: Array.from({ length: score })">
<span class="glyphicon-star">*</span>
