element.className

className gets and sets the value of the class attribute of the specified element.

Syntax

var cName = elementNodeReference.className;
elementNodeReference.className = cName;

• cName is a string variable representing the class or space-separated classes of the current element.

Example

var elm = document.getElementById("div1");

if (elm.className === "fixed") {
  // skip a particular class of element
  goNextElement();
}

Notes

The name className is used for this property instead of class because of conflicts with the "class" keyword in many languages which are used to manipulate the DOM.
