Need some assistance with grouped buttons. Let's consider a scenario where there are 5 buttons on an HTML page. When the 3rd button is clicked, buttons from 0 to 3 should change color and the function should return 3. Similarly, when the 5th button is clicked, buttons from 0 to 5 should change color and return 5 using JavaScript.
Thank you in advance!
To achieve this, you may need to utilize scripts (although there are other simple methods available). Below is an implementation using jQuery.
Using jQuery, you can select all previous siblings with prevAll() and include the clicked button itself with andSelf(). Here is a basic example as no code was provided.
$('.btn').click(function() {
$(this).prevAll('.btn').andSelf().addClass('bg-red');
$(this).nextAll('.btn').removeClass('bg-red');
console.log($(this).data('value'));
});.bg-red{
background-color: red;
