漂亮的照片集链接问题

标签: javascript jquery html hyperlink lightbox

昨天一个好的堆栈溢出用户帮助我从DIV元素而不是A元素触发Jquery Prettyphoto灯箱。

您可以找到解决方案here

这很有用......差不多。

漂亮的照片会查找引用它的所有链接,然后将它们编译成iframe的幻灯片。通常,当您点击链接时,它会打开与我点击的链接对应的iframe灯箱。

然而,使用这个新的DIV解决方案,它可以打开它在页面上找到的第一个iframe链接,而不是我点击的链接。

这显然必须发生,因为我已经改变了

中的javascript调用代码
<script type="text/javascript" charset="utf-8">
    $(document).ready(function(){
        $("a[rel^='prettyPhoto[iframes]']").prettyPhoto();
    });
</script>

<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。

我要发布整个JS文件。也许有人可以看到我需要更改的javascript以使这个DIV元素像A元素一样工作。

看起来漂亮的照片代码明确使用rel属性,您的div是否具有rel?您正在$("div[class^='menuitem[iframes]']").prettyPhoto();

上调用代码

但是,漂亮的照片正在寻找theRel = $(this).attr('rel');并与之竞争。
