如何在fancybox中获取当前图像索引? [英] How to get current image index in fancybox?

问题描述

我正在尝试在fancybox画廊中获取当前图像索引.文档中有一个pos方法，但它只是setter方法，不适用于getter.

I am trying to get current image index in fancybox gallery. There is a pos method in documentation but it is just setter method and not working for getter.

$.fancybox.pos(3) // works fine
var index = $.fancybox.pos() // does not work . It returns undefined. 

我知道pos被设计为设置方法，但我需要知道 fancybox画廊中的当前图像索引.
我怎么知道当前的图像索引?

I understand that pos is designed as setter method but i need to know current image index in fancybox gallery.
How can i know current image index ?

推荐答案

类似以下内容应该可以:

Something like the following should do just fine:

var src = $('#fancybox-img').attr('src'); // Looks for the *fancyboxed* image
var idx = $('a[href="'+src+'"]').index(); // Gets the index of the thumbnail

如果您使用某些自定义DOM层次结构，则您可能必须采用此解决方案.

You may have to adapt this solution if you use some custom DOM hierarchy.
