  You can use the classList property in JavaScript to check if an element has a specific class. Here's an example: var element = document.getElementById('elementId'); if (element.classList.contains('className')) { // Do something } else { // Do something else }

  To check if an element has a specific class using JavaScript, you can use the hasClass() function. Here's an example: function hasClass(element, className) { return element.classList.contains(className); } var element = document.getElementById('elementId'); if (hasClass(element, 'className')) { // Do something } else { // Do something else }

  If you're using the BYDFi cryptocurrency website, you can use the hasClass() function provided by the BYDFi JavaScript library. Here's an example: var element = document.getElementById('elementId'); if (BYDFi.hasClass(element, 'className')) { // Do something } else { // Do something else }
