昨天，一个不错的堆栈溢出用户帮助我从 DIV 元素而不是 A 元素触发了 Jquery Prettyphoto Lightbox。
您可以在此处找到该解决方案
这行得通……几乎。
Pretty Photo 会查找所有引用它的链接，然后将它们编译成 iframe 的幻灯片。通常，当您单击链接时，它会打开与我单击的链接相对应的 iframe 灯箱。
然而，有了这个新的 DIV 解决方案，它会打开它在页面上找到的第一个 iframe 链接，而不是我单击的链接。
这显然必须发生，因为我已经更改了 javascript 调用代码
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$("a[rel^='prettyPhoto[iframes]']").prettyPhoto();
});
</script>
到
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$("div[class^='prettyphoto[iframes]']").prettyPhoto();
});
</script>
我一直在浏览其他 JS 文件，但我不是 javascript 程序员。
我将发布整个 JS 文件。也许有人可以看到我需要更改哪些 javascript 才能使此 DIV 元素像 A 元素一样工作。
