TIL how to check if a dom element has a specific class

POSTED ON:

TAGS: js css

Trying to figure out if your button has a .red or .blue class in JS?
Destructure the classList into an array so you can use include().

const theButtonsClasses = [ ...document.querySelector("#theButton").classList];

if (theButtonsClasses.includes("red")) {
  console.log("This button has the red class!");
} else if (theButtonsClasses.includes("blue")) {
    console.log("This button has the blue class!");
}
