How Can I Efficiently Locate DOM Elements Based on Attribute Values?

Locating Elements in DOM Based on Attribute Values

In web development, it's often necessary to access elements in the Document Object Model (DOM) based on specific attribute values.

Native DOM API Approach

Modern browsers provide the querySelectorAll method, which allows you to search for elements using CSS-like selectors. To find an element based on an attribute value, use the following syntax:

document.querySelectorAll('[attribute-name="attribute-value"]');

For example, to find all elements with the data-foo attribute set to "value":

document.querySelectorAll('[data-foo="value"]');

Note that this method has browser compatibility limitations (see references below for details).

jQuery Alternative

If you need to support older browsers (IE9 and below), you can use the jQuery library:

$('[data-foo="value"]');
