超大尺寸-获取上一张/下一张幻灯片的标题？

Question

Is there a way to get the title of previous or next slide in supersized.js plugin? API allows to get the title only of current slide.

Thanks!

Try this:

var currentSlide = vars.current_slide, // zero-based index
    slides = api.options.slides,
    totalSlides = slides.length - 1,

    nextSlideTitle = api.options.slides[ (currentSlide + 1 < totalSlides) ? currentSlide + 1 : 0 ].title,
    prevSlideTitle = api.options.slides[ (currentSlide - 1 > 0) ? currentSlide - 1 : totalSlides ].title;
