hi guys hope someone could help me on this: so the problem is when i try to check the percentage if is bigger or smaller and give it a stroke to the SVG it always returns me the color of the first svg element and it passes to all the others, and i cant see why is that, what im doing wrong. Any help on this??

Answer 1

When you call setStrokeColor you set the percentage to all elements with the class "circle" not just the one you just added. You call the function when you build the original html.

<svg viewBox="0 0 36 36" class="circular-chart">
  <path class="circle ${setStrokeColor(moive.vote_average)}"
    stroke-dasharray="${movie.vote_average * 10}, 100"
    d="M18 2.0845
    a 15.9155 15.9155 0 0 1 0 31.831
    a 15.9155 15.9155 0 0 1 0 -31.831"
   />
 </svg>

function setStrokeColor(percent) {
   circleStrokeRate.forEach(circle => {
       if (percent < 40) {
          return "circle-red";
       } else if (percent < 70) {
          return "circle-darkorange";
       } else {
          return "circle-lime";
       }
   });

}
