SVGUseElement: x property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The x read-only property of the SVGUseElement interface describes the x-axis coordinate of the start point of the referenced element as an SVGAnimatedLength. It reflects the computed value of the x attribute on the <use> element.

The attribute value is a <length>, <percentage>, or <number>. The numeric value of the SVGAnimatedLength.baseVal is the x-coordinate of the top-left corner of the referenced element in the user coordinate system.

Value

An SVGAnimatedLength.

Examples

Given the following SVG:

html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <circle id="circle1" cx="50" cy="50" r="40" fill="blue" />
    <circle id="circle2" cx="50" cy="50" r="40" fill="red" />
  </defs>
  <use x="50%" y="50%" href="#circle1" />
  <use x="25%" y="50%" href="#circle2" />
</svg>

We can access the computed values of the x attributes:

js
const uses = document.querySelectorAll("use");
const xUse1 = uses[0].x;
const xUse2 = uses[1].x;

console.log(xUse1.baseVal.value); // output: 100 (50% of 200)
console.log(xUse2.baseVal.value); // output: 50 (25% of 200)
