addClass Method

Summary

Adds the specified class string to the HTML or SVG element's current class list.

Syntax

TypeScript

JavaScript

addClass = function( 
   element, 
   className 
)

static addClass( 
   element: HTMLElement, 
   className: string 
): void;

Parameters

element

HTML or SVG element to add the class to.

className

AddClass will first internally call HasClass to avoid duplicate work.
