jQuery SVG, why can’t I addClass?

by

Edit 2016: read the next two answers.

  • JQuery 3 fixes the underlying issue
  • Vanilla JS: element.classList.add('newclass') works in modern browsers

JQuery (less than 3) can’t add a class to an SVG.

.attr() works with SVG, so if you want to depend on jQuery:

// Instead of .addClass("newclass")
$("#item").attr("class", "oldclass newclass");
// Instead of .removeClass("newclass")
$("#item").attr("class", "oldclass");

And if you don’t want to depend on jQuery:

var element = document.getElementById("item");
// Instead of .addClass("newclass")
element.setAttribute("class", "oldclass newclass");
// Instead of .removeClass("newclass")
element.setAttribute("class", "oldclass");
