HTMLScriptElement: noModule property
The noModule
property of the HTMLScriptElement
interface is a boolean value that indicates whether the script should be executed in browsers that support ES modules. Practically, this can be used to serve fallback scripts to older browsers that do not support JavaScript modules.
It reflects the nomodule
attribute of the <script>
element.
Value
A boolean, true
means that the script should not be executed in browsers that support ES modules, false
otherwise.
Examples
html
<script id="el" nomodule>
// If the browser supports JavaScript modules, the following script will not be executed.
console.log("The browser does not support JavaScript modules");
</script>
js
const el = document.getElementById("el");
console.log(el.noModule); // Output: true
