Fancybox, when I open group of images and click on next with using “start index” - it's not working normally

问题

When I open group of images with fancybox "Index of start", I have a problem.

//"img[2]" it's img with rel=2

When I click on img, it's opens. After load, when I click "prev Img" - it's working normally, but on click "next img" - Gallery start playing from img[0]. using fancyBox v2.0.3. in action: http://youtu.be/1dii1qC9cOM

HTML:

<ul class="gallery">
    <li>
        <a rel="0" data-fancybox-group="PHOTOGALLERY"> <img alt="" src="1.jpg"> </a>
    </li>
    <li>
        <a rel="1" data-fancybox-group="PHOTOGALLERY"> <img alt="" src="2.jpg"> </a>
    </li>
    <li>
        <a rel="2" data-fancybox-group="PHOTOGALLERY"> <img alt="" src="3.jpg"> </a>
    </li>
    <li>
        <a rel="3" data-fancybox-group="PHOTOGALLERY"> <img alt="" src="4.jpg"> </a>
    </li>
</ul>

JS:

// Using group of images, received from ajax
    var hrefList = new Array;
    for (var i in data) {
      hrefList[i] = data[i].PATH
    }    
    ul.find('a').live('click',function(e){
      e.preventDefault();
      var himself = $(this);
      $.fancybox( hrefList, {
        'index': himself.attr('rel')
      });
    });

You don't need to use .live() with fancybox v2.x since it already handles present and future (dynamically added) elements. Additionally fancybox uses either data-fancybox-group or rel to group images within a gallery of existing elements but since you are creating a manual gallery from array, you don't actually need either of them so you html can be as simple like (even you wouldn't need the <a> tag but let's leave it like that):

<ul class="gallery">
 <li>
  <a><img alt="" src="1.jpg" /></a>
 </li>
 <li>
  <a><img alt="" src="2.jpg" /></a>
 </li>
 <li>
  <a><img alt="" src="3.jpg" /></a>
 </li>
 <li>
  <a><img alt="" src="4.jpg" /></a>
 </li>
</ul>

Then, in order to get the right index for each thumbnail you may tweak your js like:

var hrefList = new Array;
for (var i in data) {
 hrefList[i] = data[i].PATH
} 
$("ul.gallery a").each(function(e){
 $(this).click(function(){
  $.fancybox( hrefList, {
   index: e,
   type: 'image'    
  }); //fancybox        
 });//click
});//each

that will always give you the gallery that starts with the right index.

Notice that you don't need preventDefault() either since there isn't any href set for each anchor
