i am trying to get one class from multiple classes in javascript

CodePudding user response：

Instead of using ele.getAttribute("class");

Use the classList property.

let boxesId = ele.classList[2];

classList will return a list of all the classes. See documantation

Why you wanna do this? Sorry i can't understand. But if you wann check if a element have a clas you can use the method includes.

element.classList.contains(className)
