Jquery图库的问题

标签： javascript jquery javascript-events gallery image-gallery

现在我遇到了相当困难的问题..

我在互联网上找到了这个代码，并想知道我是否可以产生这种效果： 当我点击大图像或您指定的任何其他位置时，我的图像可以以某种方式放大或弹出（在同一窗口中），背景暗淡。 我找到了很多脚本，我可以用它来实现，但不知怎的，我无法在这段代码中实现它。

所以这是代码，将其复制并粘贴到您的程序中;每个建议都会很棒

答案 0 :(得分：0)

我会从previous question复制我的答案：

该术语是灯箱。有很多jQuery lightbox plugins。我对FancyBox有很好的经验。

要使用它们，您可以定位所有具有直接子img标记的锚标记，例如：

$('a:has(img)').fancybox();
