{{APIRef("SVG")}}
The x read-only property of the {{domxref("SVGPatternElement")}} interface describes the x-axis coordinate of the start point of the pattern as an {{domxref("SVGAnimatedLength")}}. It reflects the computed value of the {{SVGAttr("x")}} attribute on the {{SVGElement("pattern")}} element.
The attribute value can be a <length>, <percentage>, or <number>. The numeric value of the {{domxref("SVGAnimatedLength.baseVal")}} is the x-coordinate of the pattern's starting point in the user coordinate system.
An {{domxref("SVGAnimatedLength")}}.
Given the following SVG:
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
<defs>
<!-- First pattern -->
<pattern
id="pattern1"
x="50"
width="20"
height="20"
patternUnits="userSpaceOnUse">
<circle cx="10" cy="10" r="10" fill="blue" />
</pattern>
<!-- Second pattern -->
<pattern
id="pattern2"
x="100"
width="20"
height="20"
patternUnits="userSpaceOnUse">
<circle cx="10" cy="10" r="10" fill="red" />
</pattern>
</defs>
<!-- Using the patterns -->
<rect x="0" y="0" width="100" height="100" fill="url(#pattern1)" />
<rect x="100" y="0" width="100" height="100" fill="url(#pattern2)" />
</svg>
We can access the computed values of the x attributes:
const patterns = document.querySelectorAll("pattern");
console.log(patterns[0].x.baseVal.value); // output: 50
console.log(patterns[1].x.baseVal.value); // output: 100
