SVGForeignObjectElement: width property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The width read-only property of the SVGForeignObjectElement interface describes the width of the <foreignObject> element. It reflects the computed value of the width attribute on the <foreignObject> element.
The attribute value is a <length>, <percentage>, or <number>. The numeric value of the SVGAnimatedLength.baseVal is the y-coordinate of the <foreignObject> element in the user coordinate system.
Value
Example
Given the following SVG:
html
<svg viewBox="0 0 200 200" xmlns="https://www.w3.org/2000/svg">
<defs>
<foreignObject id="object1" x="50" y="75" width="100" height="50">
<div xmlns="https://www.w3.org/1999/xhtml">
<p>This is a foreign object.</p>
</div>
</foreignObject>
<foreignObject id="object2" x="25%" y="50%" width="10%" height="10%">
<div xmlns="https://www.w3.org/1999/xhtml">
<p>This is another foreign object.</p>
</div>
</foreignObject>
</defs>
<rect x="0" y="0" width="200" height="100" fill="lightblue" />
<rect x="0" y="100" width="200" height="100" fill="lightgreen" />
</svg>
We can access the computed values of the width attributes:
js
const foreignObjects = document.querySelectorAll("foreignObject");
const widthObject1 = foreignObjects[0].width;
const widthObject2 = foreignObjects[1].width;
console.dir(widthObject1.baseVal.value); // output: 100
console.dir(widthObject2.baseVal.value); // output: 20 (10% of 200)
