漂亮的照片集链接问题 [英] Pretty Photo Set linking Issues
本文介绍了漂亮的照片集链接问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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.
Yesterday a nice stack overflow user helped me to trigger the Jquery Prettyphoto Lightbox from a DIV element rather than an A element.
您可以在此处
这行得通...差不多.
This works... Almost.
Pretty Photo查找引用它的所有链接，然后将它们编译为iframe幻灯片.通常，当您点击链接时，它会打开与我点击的链接相对应的iframe灯箱.
Pretty Photo looks for all the links that reference it and then compiles them into a slideshow of iframes. Normally when you click on a link it will open up the iframe lightbox corresponding to the link i clicked on.
但是，通过这种新的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.
However with this new DIV solution it is opening up to the first iframe link it finds on the page, rather than the link I click on.
这肯定是正在发生的，因为我更改了的javascript调用代码
This must obviously be happening because I have altered the javascript call code from
<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>
我正在浏览其他JS文件，但我不是JavaScript程序员.
I have been going through the other JS files but I am not a javascript programmer.
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DIV元素像A元素一样工作.
I am going to post the entire JS file. Maybe someone can see what javascript I need to change to make this DIV element work like an A element.

推荐答案
看起来漂亮的照片代码正在显式地使用rel属性，您的div有关系吗?您正在$("div[class^='menuitem[iframes]']").prettyPhoto();
It looks like the pretty photos code is using the rel attribute explicitly, do your div's have rel? You are calling the code on $("div[class^='menuitem[iframes]']").prettyPhoto();
但是随后漂亮的照片正在寻找theRel = $(this).attr('rel');并以此为依据.
But then pretty photos is looking for theRel = $(this).attr('rel'); and running against that.
这篇关于漂亮的照片集链接问题的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
