jquery - fancybox thumbs 没有办法让它工作

标签 jquery html css fancybox

invisible thumb我正在使用 prettyphoto 并想切换到 fancybox，我的画廊正在使用 isotope 进行滤镜和动画处理，但我认为这不是问题所在。 图像出现，但没有拇指!在开发工具中，当选择图片时，有一个名为 fancybox-thumbs 的 div 但它是不可见的!请帮忙

(function ($) {
	//Shortcut for fancyBox object
	var F = $.fancybox;

	//Add helper object
	F.helpers.thumbs = {
		defaults : {
			width    : 50,       // thumbnail width
			height   : 50,       // thumbnail height
			position : 'bottom', // 'top' or 'bottom'
			source   : function ( item ) {  // function to obtain the URL of the thumbnail image
				var href;

				if (item.element) {
					href = $(item.element).find('img').attr('src');
				}

				if (!href && item.type === 'image' && item.href) {
					href = item.href;
				}

				return href;
			}
		},

		wrap  : null,
		list  : null,
		width : 0,

		init: function (opts, obj) {
			var that = this,
				list,
				thumbWidth  = opts.width,
				thumbHeight = opts.height,
				thumbSource = opts.source;

			//Build list structure
			list = '';

			for (var n = 0; n < obj.group.length; n++) {
				list += '<li><a style="width:' + thumbWidth + 'px;height:' + thumbHeight + 'px;" href="javascript:jQuery.fancybox.jumpto(' + n + ');"></a></li>';
			}

			this.wrap = $('<div id="fancybox-thumbs"></div>').addClass(opts.position).appendTo('body');
			this.list = $('<ul>' + list + '</ul>').appendTo(this.wrap);

			//Load each thumbnail
			$.each(obj.group, function (i) {
				var href = thumbSource( obj.group[ i ] );

				if (!href) {
					return;
				}

				$("<img />").load(function () {
					var width  = this.width,
						height = this.height,
						widthRatio, heightRatio, parent;

					if (!that.list || !width || !height) {
						return;
					}

					//Calculate thumbnail width/height and center it
					widthRatio  = width / thumbWidth;
					heightRatio = height / thumbHeight;

					parent = that.list.children().eq(i).find('a');

					if (widthRatio >= 1 && heightRatio >= 1) {
						if (widthRatio > heightRatio) {
							width  = Math.floor(width / heightRatio);
							height = thumbHeight;

						} else {
							width  = thumbWidth;
							height = Math.floor(height / widthRatio);
						}
					}

					$(this).css({
						width  : width,
						height : height,
						top    : Math.floor(thumbHeight / 2 - height / 2),
						left   : Math.floor(thumbWidth / 2 - width / 2)
					});

					parent.width(thumbWidth).height(thumbHeight);

					$(this).hide().appendTo(parent).fadeIn(300);

				}).attr('src', href);
			});

			//Set initial width
			this.width = this.list.children().eq(0).outerWidth(true);

			this.list.width(this.width * (obj.group.length + 1)).css('left', Math.floor($(window).width() * 0.5 - (obj.index * this.width + this.width * 0.5)));
		},

		beforeLoad: function (opts, obj) {
			//Remove self if gallery do not have at least two items
			if (obj.group.length < 2) {
				obj.helpers.thumbs = false;

				return;
			}

			//Increase bottom margin to give space for thumbs
			obj.margin[ opts.position === 'top' ? 0 : 2 ] += ((opts.height) + 15);
		},

		afterShow: function (opts, obj) {
			//Check if exists and create or update list
			if (this.list) {
				this.onUpdate(opts, obj);

			} else {
				this.init(opts, obj);
			}

			//Set active element
			this.list.children().removeClass('active').eq(obj.index).addClass('active');
		},

		//Center list
		onUpdate: function (opts, obj) {
			if (this.list) {
				this.list.stop(true).animate({
					'left': Math.floor($(window).width() * 0.5 - (obj.index * this.width + this.width * 0.5))
				}, 150);
			}
		},

		beforeClose: function () {
			if (this.wrap) {
				this.wrap.remove();
			}

			this.wrap  = null;
			this.list  = null;
			this.width = 0;
		}

最佳答案

您可能需要将元素包装在标签中，并将类绑定(bind)到 fancybox，例如

<a class="fancybox-thumbs" href="image/1_b.jpg" rel="fancybox-thumbs" data-thumbnail="images/1_s.jpg" data-fancybox-group="gallery-1" title="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas ac augue at erat hendrerit dictum.">
    <img src="images/1_s.jpg" alt="" class="fullwidth" />
</a>

那么这段代码就可以运行了

$(document).ready(function () {
    $(".fancybox-thumbs").fancybox({
        prevEffect : 'none',
        nextEffect : 'none',
        helpers : {
            thumbs : {
                width : 50,
                height : 50,
                source : function (current) {
                    return $(current.element).data('thumbnail');
                },
            },
            title : {
                type : 'outside'

            }
        }
    });
});

除非你知道自己在做什么，否则你不需要弄乱原始的 js 和 css 文件

JSFIDDLE

注意:当然，不要忘记在您的页面中包含指向 fancybox thumbs helpers 的链接，并在 fancybox 文件之后加载它们
