Selecting element by data attribute


Is there an easy and straight-forward method to select elements based on their data attribute? For example, select all anchors that has data attribute named customerID which has value of 22.

I am kind of hesitant to use rel or other attributes to store such information, but I find it much harder to select an element based on what data is stored in it.

Accepted Answer


You should be able to omit the *, but if I recall correctly, depending on which jQuery version you’re using, this might give faulty results.

Note that for compatibility with the Selectors API (document.querySelector{,all}), the quotes around the attribute value (22) may not be omitted in this case.

Also, if you work with data attributes a lot in your jQuery scripts, you might want to consider using the HTML5 custom data attributes plugin. This allows you to write even more readable code by using .dataAttr('foo'), and results in a smaller file size after minification (compared to using .attr('data-foo')).

For people Googling and want more general rules about selecting with data-attributes:

$("[data-test]") will select any element that merely has the data attribute (no matter the value of the attribute). Including:

<div data-test=value>attributes with values</div>
<div data-test>attributes without values</div>

$('[data-test~="foo"]') will select any element where the data attribute contains foo but doesn't have to be exact, such as:

<div data-test="foo">Exact Matches</div>
<div data-test="this has the word foo">Where the Attribute merely contains "foo"</div>

$('[data-test="the_exact_value"]') will select any element where the data attribute exact value is the_exact_value, for example:

<div data-test="the_exact_value">Exact Matches</div>

but not

<div data-test="the_exact_value foo">This won't match</div>

Using $('[data-whatever="myvalue"]') will select anything with html attributes, but in newer jQueries it seems that if you use $(...).data(...) to attach data, it uses some magic browser thingy and does not affect the html, therefore is not discovered by .find as indicated in the previous answer.

Verify (tested with 1.7.2+) (also see fiddle): (updated to be more complete)

var $container = $('<div><div id="item1"/><div id="item2"/></div>');

// add html attribute
var $item1 = $('#item1').attr('data-generated', true);

// add as data
var $item2 = $('#item2').data('generated', true);

// create item, add data attribute via jquery
var $item3 = $('<div />', {id: 'item3', data: { generated: 'true' }, text: 'Item 3' });

// create item, "manually" add data attribute
var $item4 = $('<div id="item4" data-generated="true">Item 4</div>');

// only returns $item1 and $item4
var $result = $container.find('[data-generated="true"]');

I haven't seen a JavaScript answer without jQuery. Hopefully it helps someone.

var elements = document.querySelectorAll('[data-customerID="22"]');

elements[0].innerHTML = 'it worked!';
<a data-customerID='22'>test</a>



To select all anchors with the data attribute data-customerID==22, you should include the a to limit the scope of the search to only that element type. Doing data attribute searches in a large loop or at high frequency when there are many elements on the page can cause performance issues.

Get NodeList of elements

var elem = document.querySelectorAll('[data-id="container"]')

html: <div data-id="container"></div>

Get the first element

var firstElem = document.querySelector('[id="container"]')

html: <div id="container"></div>

Target a collection of nodes which returns a nodelist



<div class="footer">
    <div data-id="12"></div>
    <div data-id="22"></div>

Get elements based on multiple (OR) data values



<div data-selection="20"></div>
<div data-section="12"></div>

Get elements based on combined (AND) data values



<div data-prop1="12" data-prop2="20"></div>

Get items where the value starts with
