我正在尝试使用幻灯片放映创建一个jsp主页。我正在使用eclipse ide,JSP,CSS和JS。我能够得到幻灯片放映一切正常,但幻灯片放映中的图像高度不同我给所有图像的高度为60%。但每张图片都显示出自己的原始高度。任何人都可以指导需要纠正的问题。以下是代码。

var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides(slideIndex += n);
}

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";
}
.mySlides {
  display: none
}


/* Slideshow container */

.slideshow-container {
  max-width: 1000px;
  position: relative;
  margin: auto;
}


/* Next & previous buttons */

.prev,
.next {
  cursor: pointer;
  position: absolute;

  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
}


/* Position the "next button" to the right */

.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}


/* On hover, add a black background color with a little bit see-through */

.prev:hover,
.next:hover {
  background-color: rgba(0, 0, 0, 0.8);
}


/* The dots/bullets/indicators */

.dot {
  cursor: pointer;
  height: 13px;
  width: 13px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;

@-webkit-keyframes fade {

  }
}

  from {

  }
  to {
    opacity: 1
  }
}

欢迎来到SO,

您需要为幻灯片容器定义高度,例如幻灯片容器,所以在css中,

   .slideshow-container{
height:300px;
}

这应该可以解决问题。!希望这会有所帮助。
