Element: querySelectorAll() method

The Element method querySelectorAll() returns a static (not live) NodeList representing a list of elements matching the specified group of selectors which are descendants of the element on which the method was called.





A string containing one or more selectors to match against. This string must be a valid CSS selector string; if it's not, a SyntaxError exception is thrown. See Locating DOM elements using selectors for more information about using selectors to identify elements. Multiple selectors may be specified by separating them using commas.

Note that the selectors are applied to the entire document, not just the particular element on which querySelectorAll() is called. To restrict the selector to the element on which querySelectorAll() is called, include the :scope pseudo-class at the start of the selector. See the selector scope example.

Note: Characters which are not part of standard CSS syntax must be escaped using a backslash character. Since JavaScript also uses backslash escaping, special care must be taken when writing string literals using these characters. See Escaping special characters for more information.

Return value

A non-live NodeList containing one Element object for each descendant node that matches at least one of the specified selectors.

Note: If the specified selectors include a CSS pseudo-element, the returned list is always empty.


SyntaxError DOMException

Thrown if the syntax of the specified selectors string is not valid.

// const refs = [...document.querySelectorAll(`[class~="funnel-chart-percent"]`)];

Obtaining a list of matches

To obtain a NodeList of all of the <p> elements contained within the element "myBox":

const matches = myBox.querySelectorAll("p");

This example returns a list of all <div> elements within "myBox" with a class of either "note" or "alert":

const matches = myBox.querySelectorAll("div.note, div.alert");

Here, we get a list of the document's <p> elements whose immediate parent element is a <div> with the class "highlighted" and which are located inside a container whose ID is "test".

const container = document.querySelector("#test");
const matches = container.querySelectorAll("div.highlighted > p");

This example uses an attribute selector to return a list of the <iframe> elements in the document that contain an attribute named "data-src":

const matches = document.querySelectorAll("iframe[data-src]");

Here, an attribute selector is used to return a list of the list items contained within a list whose ID is "userlist" which have a "data-active" attribute whose value is "1":

const container = document.querySelector("#userlist");
const matches = container.querySelectorAll("li[data-active='1']");

Accessing the matches

Once the NodeList of matching elements is returned, you can examine it just like any array. If the array is empty (that is, its length property is 0), then no matches were found.

Otherwise, you can use standard array notation to access the contents of the list. You can use any common looping statement, such as:

const highlightedItems = userList.querySelectorAll(".highlighted");

highlightedItems.forEach((userItem) => {

Note: NodeList is not a genuine array, that is to say it doesn't have array methods like slice, some, map, etc. To convert it into an array, try Array.from(nodeList).

Selector scope

The querySelectorAll() method applies its selectors to the whole document: they are not scoped to the element on which the method is called. To scope the selectors, include the :scope pseudo-class at the start of the selector string.


In this example the HTML contains:

  • two buttons: #select and #select-scope
  • three nested <div> elements:#outer, #subject, and #inner
  • a <pre> element which the example uses for output.
<button id="select">Select</button>
<button id="select-scope">Select with :scope</button>

<div id="outer">
  <div id="subject">
    <div id="inner">.inner</div>

<pre id="output"></pre>


In the JavaScript, we first select the #subject element.

When the #select button is pressed, we call querySelectorAll() on #subject, passing "#outer #inner" as the selector string.

When the #select-scope button is pressed, we again call querySelectorAll() on #subject, but this time we pass ":scope #outer #inner" as the selector string.

const subject = document.querySelector("#subject");

const select = document.querySelector("#select");
select.addEventListener("click", () => {
  const selected = subject.querySelectorAll("#outer #inner");
  output.textContent = `Selection count: ${selected.length}`;

const selectScope = document.querySelector("#select-scope");
selectScope.addEventListener("click", () => {
  const selected = subject.querySelectorAll(":scope #outer #inner");
  output.textContent = `Selection count: ${selected.length}`;


When we press "Select", the selector selects all elements with an ID of inner that also have an ancestor with an ID of outer. Note that even though #outer is outside the #subject element, it is still used in selection, so our #inner element is found.

When we press "Select with :scope", the :scope pseudo-class restricts the selector scope to #subject, so #outer is not used in selector matching, and we don't find the #inner element.
