在幻灯片自定义HTML内容

为了使PhotoSwipe显示HTML内容的幻灯片，你需要在幻灯片对象定义html属性。它应该包含HTML字符串或DOM元素对象。

 1 var items = [
 2     // slide 1 with HTML
 3     {
 4         html: '<div><h1>Any HTML <a href="http://example.com">content</a></h1></div>'
 5     },
 6 
 7     // slide 2 with image
 8     {
 9         src: 'path/to/image.jpg',
10         w:600,
11         h:200
12     }
13 ];
14 
15 
16 // initialise as usual
17 var gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items, options);
18 
19 // You don't necessarily need to have "html" property in slide object initially.
20 // You may create it dynamically in gettingData event:
21 /*
22     gallery.listen('gettingData', function(index, item) {
23         if(index === 3) {
24             item.html = '<div>Dynamically generated HTML ' + Math.random() + '</div>';
25         }
26 
27     });
28 */
29 
30 // Note that init() method is called after gettingData event is bound
31 gallery.init();

其他重要事项：

为了避免与第三方模块，具有html属性幻灯片冲突，不应该有SRC（图像）属性。

PhotoSwipe是专为图像，而不是文本内容的滚轮。使用“自定义HTML”功能作为此外，例如，在相关的画廊，一个介绍的幻灯片，或图像之间的广告幻灯片。

我们强烈不建议添加视频或使用此方法的音频内容（包括YouTube，Vimeo的等内部框架）。随着HTML5视频块触摸了它的活动在很多移动浏览器（用户将无法刷卡的话）。如果你真的需要在PhotoSwipe视频，您可以将其添加为当用户点击当前的幻灯片显示模式，可以动态地在DOM创建模态和.pswp__scroll换行元素之后添加它。

如果启用了最初的放大/缩小的过渡，如果当前的幻灯片有HTML PhotoSwipe将自动禁用它，简单的淡入淡出的过渡将被用来代替。

默认情况下PhotoSwipe将使只是链接（<A>）及其子元素click事件。要改变这种行为，直视isClickable元素选项或防止拖动事件的事件。

不支持HTML滑块的放大，但。

html:
