<div id="foo" data-foo="foo_id" data-foo2="foo_id2" data-foo3="foo_id3" data-foo4="foo_id4" data-foo5="foo_id4"></div>
Tests:
getAttribute
var element = document.getElementById("foo"); var i = 10000; while (i--) { var foo = element.getAttribute("data-foo"); var foo2 = element.getAttribute("data-foo2"); var foo3 = element.getAttribute("data-foo3"); var foo4 = element.getAttribute("data-foo4"); var foo5 = element.getAttribute("data-foo5"); }
dataset
var element = document.getElementById("foo"); var i = 10000; while (i--) { var foo = element.dataset.foo; var foo2 = element.dataset.foo2; var foo3 = element.dataset.foo3; var foo4 = element.dataset.foo4; var foo5 = element.dataset.foo5; }
dataset destructurization
var element = document.getElementById("foo"); var i = 10000; while (i--) { var { foo, foo2, foo3, foo4, foo5 } = element.dataset; }
