ParentNode.querySelectorAll()

The ParentNode mixin defines the querySelectorAll() method as returning a NodeList representing a list of elements matching the specified group of selectors which are descendants of the object on which the method was called.

If you need only a single result, consider the querySelector() method instead.

Syntax

elementList = parentNode.querySelectorAll(selectors);

Parameters

selectors
A DOMString 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: Characters which are not part of standard CSS syntax must be escaped using a backslash character. Since JavaScript also uses backspace 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.

Exceptions

SyntaxError
The syntax of the specified selectors string is not valid.

Examples

To obtain a NodeList of all of the <p> elements in the document:

var matches = document.querySelectorAll("p");

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

var matches = document.querySelectorAll("div.note, div.alert");

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

var container = document.querySelector("#test");
var 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":

var 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":

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

User notes

querySelectorAll() behaves differently than most common JavaScript DOM libraries, which might lead to unexpected results.

HTML

Consider this HTML, with its three nested <div> blocks.

<div class="outer">
  <div class="select">
    <div class="inner">
    </div>
  </div>
</div>

JavaScript

var select = document.querySelector('.select');
var inner = select.querySelectorAll('.outer .inner');
inner.length; // 1, not 0!

In this example, when selecting ".outer .inner" in the context the <div> with the class "select", the element with the class ".inner" is still found, even though .outer is not a descendant of the base element on which the search is performed (".select"). By default, querySelectorAll() only verifies that the last element in the selector is within the search scope.

The :scope pseudo-class restores the expected behavior, only matching selectors on descendants of the base element:

var select = document.querySelector('.select');
var inner = select.querySelectorAll(':scope .outer .inner');
inner.length; // 0
