document.scripts returns a live HTMLCollection of every <script> element in the document (MDN). You can use it like an array — length, indexes, and loops.
Read the notes below before you get or set this property. Prefer feature detection when support is limited.
Use document.scripts. Start with this line.
document.scripts| Call | What it does |
|---|---|
document.scripts | Primary signature. |
Built into the browser. Read or assign document.scripts — no import required.
document.scripts| Parameter | Description |
|---|---|
| HTMLCollection | Required. Live list of <script> |
| Writable? | Optional. Read-only property — mutate the DOM instead |
| Return Value | Description |
|---|---|
| * | Live HTMLCollection of HTMLScriptElement |
MDN pattern: check document.scripts.length.
const scripts = document.scripts;
if (scripts.length) {
console.log("This page has scripts!");
console.log("count:", scripts.length);
}<script>.length — 0 is falsy; any count is truthy.alert; we use console.log).length for the exact count.src and typeInspect each HTMLScriptElement in the collection.
for (const s of document.scripts) {
console.log(
s.getAttribute("src") || "(inline)",
s.type || "text/javascript"
);
}for…of — each value is an HTMLScriptElement.getAttribute("src") for the authored path; empty means inline.type — default classic scripts often omit it.s.src alone is usually an absolute URL for external scripts.Append a <script> and watch document.scripts.length update.
const list = document.scripts;
console.log(list.length); // before
const s = document.createElement("script");
s.textContent = "// demo";
document.body.appendChild(s);
console.log(list.length); // after — increased by 1document.scripts again.<script> element.HTMLCollection tracks the DOM.querySelectorAll("script") result would stay frozen.Document.scripts is a core HTML Document collection. MDN marks it Baseline Widely available (since June 2018).
Live HTMLCollection of every <script> element. Safe for everyday use.
Bottom line: Use freely in modern browsers. See the MDN scripts reference.
