Examples

The following example shows an SVG which contains a {{SVGElement("polyline")}} with five coordinate pairs. A new {{domxref("DOMPoint")}} is created, then replaces the point at index 1 (the second item in the list).

<svg id="svg" viewBox="-10 -10 120 120" xmlns="http://www.w3.org/2000/svg">
  <polyline
    id="example"
    stroke="black"
    fill="none"
    points="50,0 21,90 98,35 2,35 79,90" />
</svg>

const example = document.getElementById("example");
const point = document.getElementById("svg").createSVGPoint();
point.y = 10;
point.x = 10;
console.log(example.points.replaceItem(point, 1));
