Js remove all classes from element

December 12, 2023 by Tarik

Do not access className from the style object, access it directly like

this.className

document.querySelector('button').onclick = function() {
  this.className="";
}

.myClass {

  color:red;
  
}

.second {

  color:green;
}

<button id="button" class="myClass second">click me</button>
