我已经能够让 PhotoSwipe 处理缩略图中显示的图像，使用不同的外部，更复杂，javascript，但由于某种原因，这个 "simplified" 演示一直让我感到困惑参考错误。我已经尝试在结束 body 标签之前加载 header 中的 PhotoSwipe javascript；不起作用。

我还尝试了调用新的 PhotoSwipe 构造函数的不同变体，但似乎不起作用。

Answer 1

将大写字母打错为小写字母。此行有错误：

var gallery = new PhotoSwipe(pswpElement, PhotoswipeUI_Default, items, options);

'PhotoswipeUI_Default'应该是：

PhotoSwipeUI_Default

Photoswipe 中的 's' 应该大写。

Photoswipe UI 默认未定义

Photoswipe UI Default is not defined

html

javascript

css

php
