chi mi può aiutare a modificare questo script per far caricare le immagini in modo random e non in ordine come avviene ora?
Grazie
Graziecodice:var images = [ 'assets/img/bg1.jpg', 'assets/img/bg2.jpg', 'assets/img/bg3.jpg' ]; var img = document.querySelector('#hero'); var index = 0; var iterations = 0; var updateImage = function() { /* reset index to zero if current index is greater than number of images. * increment iterations variable since it means we've done one whole loop. */ if (index >= images.length) { index = 0; iterations++; } // set the background image img.style.backgroundImage = 'url(' + images[index] + ')'; /* clear interval (stop timer) when we've reached * the number of iterations allowed. */ if (iterations >= 2) { clearInterval(interval); } else { /* increment current index in order to get next image * when this function gets called again. */ index++; } } // update first image updateImage(); // initiate timer var interval = setInterval(updateImage, 4000);
