{{APIRef("SVG")}}
The y2 read-only property of the {{domxref("SVGLineElement")}} interface describes the v-axis coordinate value of the end of a line as an {{domxref("SVGAnimatedLength")}}. It reflects the {{SVGElement("line")}} element's {{SVGAttr("y2")}} geometric attribute.
The attribute value is a <length>, <percentage>, or <number>. The numeric value of the {{domxref("SVGAnimatedLength.baseVal")}} is that end position along the y-axis in user coordinate system units.
An {{domxref("SVGAnimatedLength")}}.
Given the following SVG:
<svg viewBox="0 0 300 200" xmlns="http://www.w3.org/2000/svg">
<line x1="20" y1="30" x2="40" y2="50" stroke="blue" stroke-width="2" />
<line x1="15%" y1="5%" x2="30%" y2="60%" stroke="red" stroke-width="4" />
</svg>
We can access the computed values of the y2 attributes:
const lines = document.querySelectorAll("line");
const y2Pos0 = lines[0].y2;
const y2Pos1 = lines[1].y2;
console.dir(y2Pos0.baseVal.value); // output: 50 (the value of `y2`)
console.dir(y2Pos1.baseVal.value); // output: 120 (60% of 200)
