SVGLength: valueAsString 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 valueAsString property of the SVGLength interface represents the <length>'s value as a strin*, in the units expressed by unitType.

Setting this attribute will cause value, valueInSpecifiedUnits, and unitType to be updated automatically to reflect this setting.

Value

A string.

Examples

Setting and retrieving valueAsString

js
// Create an SVGLength object
const svg = document.querySelector("svg");
const length = svg.createSVGLength();

// Set the length as a string
length.valueAsString = "45%";
console.log(length.valueAsString); // Output: "45%"
console.log(length.unitType); // Output: 2 (SVG_LENGTHTYPE_PERCENTAGE)
console.log(length.valueInSpecifiedUnits); // Output: 45

// Change the length value
length.valueAsString = "100px";
console.log(length.valueAsString); // Output: "100px"
console.log(length.unitType); // Output: 5 (SVG_LENGTHTYPE_PX)
console.log(length.value); // Output: 100
