SVGFEMergeElement: result 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 result read-only property of the SVGFEMergeElement interface describes the assigned name of an SVG filter primitive as a SVGAnimatedString.

It reflects the result attribute of the <feMerge> element. The attribute value is a <custom-ident>. If supplied, then graphics that result from processing this filter primitive can be referenced by an in attribute on a subsequent filter primitive within the same <filter> element.

If no result attribute is defined, the filter's result.baseVal and result.animVal are empty strings, and the output of the <feMerge> filter will only be available for re-use as the implicit input into the next filter primitive if that filter primitive provides no value for its in attribute.

Value

An SVGAnimatedString.

Example

const feMergeElement = document.querySelector("feMerge");
const filterName = feMergeElement.result;
console.log(filterName.baseVal); // the filter's assigned name
