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 July 2015.
The valueAsString property of the SVGLength interface represents the <length>'s value as a string, 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
