Question

我有一个带缩略图的视频轮播。我正在尝试使视频缩略图与图像缩略图的高度相同，这是旋转木马中的最后一项。但我不想更改最后一个图像缩略图大小，我希望其余的匹配它。

以下是codepen：https://codepen.io/GabriellaFarfan/pen/vjYwzw

$(document).ready(function() {
  // get all images loaded
  var images = $(".chair-class");
  // thumbnails containers
  var thumbnailContainer = $("#thumbnails");
  var iframe1 = $('#sketchfab-iframe-1')[0];
  var iframe2 = $('#sketchfab-iframe-2')[0];
  var player1 = $f(iframe1);
  var player2 = $f(iframe2);
  // generate thumbnail images
  generateThumbnails(images, thumbnailContainer);
  // listeners for controls arrows
  $(".prev-next-button").on("click", function() {
    player1.api('pause');
    player2.api('pause');
    // get the images
    var currentImageIndex = images.index($(".chair-class[data-active=true]"));
    var isPrevious = $(this).hasClass("previous");
    var nextIndex;
    if (isPrevious) {
      if (currentImageIndex === 0) {
        nextIndex = images.length - 1;
      }

      if (currentImageIndex > 0) {
        nextIndex = currentImageIndex - 1;
      }
    } else {
      if (currentImageIndex === images.length - 1) {
        nextIndex = 0;
      }

      if (currentImageIndex < images.length - 1) {
        nextIndex = currentImageIndex + 1;
      }
    }

    // remove any active class from images
    images.removeClass("active").attr('data-active', "false");
    // get the next active image and add active class to that next current image
    var $nextImage = $(images[nextIndex]);
    var iframeId = $nextImage.data('iframe');
    if (iframeId) {
      $(images[nextIndex]).attr('data-active', "true");
      $('.sketchfab-iframe').removeClass('active');
      $('#' + iframeId).addClass('active');
    } else {
      $(images[nextIndex]).addClass("active").attr('data-active', "true");
      $('.sketchfab-iframe').removeClass('active');
    }
  });

  $(".thumb").on("click", function(event) {
    event.preventDefault();
    var images = $(".chair-class");
    var indexSelected = $(this).data("img-index");
    var currentShown = images.index($(".chair-class[data-active=true]"));
    if (currentShown === indexSelected) return false;
    player1.api('pause');
    player2.api('pause');
    images.removeClass("active").attr('data-active', "false");
    var iframeId = $(this).data('iframe');
    if (iframeId) {
      $(images[indexSelected]).attr('data-active', "true");
      $('.sketchfab-iframe').removeClass('active');
      $('#' + iframeId).addClass('active');
    } else {
      images.removeClass("active");
      $(images[indexSelected]).addClass('active').attr('data-active', "true");;
      $('.sketchfab-iframe').removeClass('active');
    }
  });

  function generateThumbnails(images, container) {
    var ul = $("<ul>");
    images.each(function(index, element) {
      var currentThumb = $("<img>");
      var li = $("<li>");
      var src = $(this).attr("src");
      currentThumb.attr("src", src);
      currentThumb.attr("class", "thumb");
      currentThumb.data("img-index", index);
      var iframe = $(this).data('iframe');
      if (iframe) {
        currentThumb.data("iframe", iframe);
      }
      li.append(currentThumb);
      ul.append(li);
    });
    container.append(ul);
  }
});

Answer 1

您可以使用max-height和max-width属性并相应地调整图像。以下是我对css代码所做的更改。

.thumb { 
  height: auto; 
  cursor: pointer;
  max-height:140px;/* using max-height property*/
  max-width:250px;
}

#thumbnails ul{
  margin: 0 auto;
  display: block;
}

#thumbnails li{
  display: inline-block;
  padding:10px;
  margin:10px;
}

试一试。希望这有效。
