javascript - Find an element in DOM based on an attribute value

Question

Can you please tell me if there is any DOM API which search for an element with given attribute name and attribute value:

Something like:

doc.findElementByAttribute("myAttribute", "aValue");

Answer 1

Modern browsers support native querySelectorAll so you can do:

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

You can use jQuery to support obsolete browsers (IE9 and older):

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