标签： javascript jquery modal-dialog slideshow lightbox

我想在不下载任何内容的情况下创建灯箱效果。我找到了一个很好的解决方案，使用Modal / Slideshow作为灯箱，效果很好。我想在一个页面上有超过1个并且无法使其工作。这是示例的链接，下面是所有代码。 https://www.w3schools.com/howto/howto_js_lightbox.asp

答案 1 :(得分：0)

我有一个部分答案，因为我正在研究相同的概念（在一个页面上有多个灯箱）并使用相同的示例代码！它的部分原因是因为我的问题仍有一些问题（第二个灯箱的标题尚未通过，并且第二个灯箱的演示区域中的＃34;活动＆＃34;图像保持不透明也。） 希望有人可以改进我所做的事情！

我发现我需要复制JS并重命名第二个灯箱的功能，然后确保你调用复制的＆amp;重命名第二个灯箱的版本：

 <meta name="viewport" content="width=device-width, initial-scale=1">

 }

 .mySlides, .mySlides2 {

 }
