HTML幻灯片插件

Question

我正在制作一个网站，其中包含我制作的 iPhone 应用程序的一些屏幕截图，并且想知道是否有某种用于 HTML 的幻灯片。我希望它有 iPhone 框架和幻灯片，中间有屏幕截图。我更喜欢用 Flash 以外的方式编写它。

提前致谢！

Answer 1

我个人是Nivo Slider 的粉丝。需要 jQuery。

Answer 2

这需要 HTML、CSS 和 Javascript。这不是我自己的答案，而是来自https://www.w3schools.com/howto/howto_js_slideshow.asp。

对于将在按钮单击时更改图片的幻灯片

var slideIndex = 1;
showSlides(slideIndex);

// Next/previous controls
function plusSlides(n) {
  showSlides(slideIndex += n);
}

// Thumbnail image controls
function currentSlide(n) {
  showSlides(slideIndex = n);
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("dot");
  if (n > slides.length) {slideIndex = 1} 
  if (n < 1) {slideIndex = slides.length}
  for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none"; 
  }
  for (i = 0; i < dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
  }
  slides[slideIndex-1].style.display = "block"; 
  dots[slideIndex-1].className += " active";
}

用于自动幻灯片

var slideIndex = 0;
showSlides();

function showSlides() {
    var i;
    var slides = document.getElementsByClassName("mySlides");
    for (i = 0; i < slides.length; i++) {
        slides[i].style.display = "none"; 
    }
    slideIndex++;
    if (slideIndex > slides.length) {slideIndex = 1} 
    slides[slideIndex-1].style.display = "block"; 
    setTimeout(showSlides, 2000); // Change image every 2 seconds
}
