有没有办法弄清楚我们是否在reveal.js的最后一张幻灯片上？

Reveal.addEventListener('slidechanged', function(event) {
    var currentSlide = event.currentSlide;
    var totalSlides = Reveal.getTotalSlides();
    
    if (currentSlide === totalSlides) {
        // 当前为最后一张幻灯片
        console.log("这是最后一张幻灯片");
    }
});

Reveal.addEventListener('slidechanged', function(event) {
    var currentSlide = event.currentSlide;
    
    if (currentSlide.classList.contains('last-slide')) {
        // 当前为最后一张幻灯片
        console.log("这是最后一张幻灯片");
    }
});
