SVGScriptElement: async property

Baseline 2025

Newly available

Since December 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The async property of the SVGScriptElement interface is a boolean value that controls how the script should be executed. It reflects the async attribute of the given <script> element. When set to true, the external script is fetched in parallel to parsing the SVG document, and the script is evaluated as soon as it becomes available.

Value

A boolean.

Examples

Accessing the async property

html
<svg xmlns="http://www.w3.org/2000/svg" width="400" height="200">
  <script id="myScript" href="script.js" async></script>
</svg>

js
const scriptElement = document.getElementById("myScript");

// Access the async property
console.log(scriptElement.async); // Output: true
