我想要的结果：

我的 HTML：

<ul class="hover_thumb_wrap">
    <li class="hover_thumb_unit">
        <a rel="prettyPhoto[18]" class="imgwrap" title="Item Title" href="http://placehold.it/800x600" style="cursor: pointer;">
        <img width="50" height="50" alt="Item Thumbnail Alt" class="attachment-50x50" src="http://placehold.it/50x50">
        </a>
    </li>
    <li class="hover_thumb_unit">
        <a rel="prettyPhoto[18]" class="imgwrap" title="Item Title" href="http://placehold.it/400x500" style="cursor: pointer;">
        <img width="50" height="50" alt="Item Thumbnail Alt" class="attachment-50x50" src="http://placehold.it/50x50">
        </a>
    </li>

</ul>

我的Javascript：

jQuery("#item-wrap a[rel^='prettyPhoto']").prettyPhoto({
            animationSpeed: 'normal', /* fast/slow/normal */
            padding: 15, /* padding for each side of the picture */
            opacity: 0.7, /* Value betwee 0 and 1 */
            showTitle: false, /* true/false */
            allowresize: true, /* true/false */
            counter_separator_label: '/', /* The separator for the gallery counter 1 "of" 2 */
            //theme: 'dark_square', /* light_rounded / dark_rounded / light_square / dark_square */
            hideflash: false, /* Hides all the flash object on a page, set to TRUE if flash appears over prettyPhoto */
            modal: false, /* If set to true, only the close button will close the window */
            callback: function() {
                var url = location.href;
                var hashtag = (url.indexOf('#!prettyPhoto')) ? true : false;
                if (hashtag) location.hash = "!";
            } /* Called when prettyPhoto is closed */,
            social_tools : ''
      });

Answer 1

问题是 prettyPhoto 验证您的图片网址。验证以 jpg|jpeg|png|gif 结尾的图像 url。所以解决方案是：

1：更改您的图片网址http://placehold.it/800x600 => http://placehold.it/800x600.jpg

2：编辑文件：jquery.prettyPhoto.js（解压版）第763行：注释这段代码

if(!pp_images[i].match(/\b(jpg|jpeg|png|gif)\b/gi)){
                    classname = 'default';
                    img_src = '';
                }else{
                    classname = '';
                    img_src = pp_images[i];
                }

并替换为

classname = '';
img_src = pp_images[i];

完毕！

<script>
    $(document).ready(function(){
    $("a[rel^='prettyPhoto["18"]']").prettyPhoto({animation_speed:'normal',theme:'pp_default',slideshow:3000, autoplay_slideshow: false});
});

</script>

将此脚本添加到您的头文件或任何其他合适的 js 文件中。
