Agar boshida tugma elementida active sinfi o‘rnatilmagan bo‘lsa, quyidagi koddan foydalaning:
Misol
// Get the container element
var btnContainer = document.getElementById("myDIV");
// Get all buttons with class="btn" inside the container
var btns = btnContainer.getElementsByClassName("btn");
// Loop through the buttons and add the active class to the current/clicked button
for (var i = 0; i < btns.length; i++) {
btns[i].addEventListener("click", function() {
var current = document.getElementsByClassName("active");
// If there's no active class
if (current.length > 0) {
current[0].className = current[0].className.replace(" active", "");
}
// Add the active class to the current/clicked button
this.className += " active";
});
