HTMLScriptElement: src property

The src property of the HTMLScriptElement interface is a string representing the URL of an external script; this can be used as an alternative to embedding a script directly within a document.

It reflects the src attribute of the <script> element.

Value

A string.

Examples

Assume the code is running on a website whose URL is https://example.com.

html
<script id="script-with-src" type="module" src="/main.js"></script>
<script id="script-without-src" type="module"></script>
js
const script_with_src = document.getElementById("script-with-src");
console.log(script_with_src.src); // Output: "https://example.com/main.js"
const script_without_src = document.getElementById("script-without-src");
console.log(script_without_src.src); // Output: ""
