jquery - Fancybox: Add Caption and other things

Question

I'd like to know how I can add more than a title (e.g a caption or a link) to the fancybox. I am aware that if I add a title="Bla" it'll show up in the box. But if I add something like caption="Blabla" to my image link, what code do I need to have in jquery.fancybox.js to pull that caption tag?

You don't need to mess with original jquery.fancybox.js file since you could add this option within your own customized fancybox script.

If you are using HTML5 DOCTYPE, you could use the data-* attribute for you caption so you can have this HTML :

<a class="fancybox" href="images/01.jpg" data-caption="This is the caption" >Open fancybox</a>

Then set your custom fancybox script and get the data-caption using the beforeShow callback like

$(document).ready(function() {
 $('.fancybox').fancybox({
  beforeShow : function(){
   this.title =  $(this.element).data("caption");
  }
 });
}); // ready

That will override the title and use the data-caption instead.

On the other hand, you may want to keep the title attribute and build the fancybox's title combining both, title and data-caption attributes so, for this HTML

<a class="fancybox" href="images/01.jpg" title="This is the title" data-caption="This is the caption">Open fancybox</a>

Use this script

$(document).ready(function() {
 $('.fancybox').fancybox({
  beforeShow : function(){
   this.title =  this.title + " - " + $(this.element).data("caption");
  }
 });
}); // ready

Additionally, you could also get the caption/title from another HTML element within your document (a <div> for instance) that can have links or other HTML elements. Check these posts for code examples: https://stackoverflow.com/a/9611664/1055987 and https://stackoverflow.com/a/8425900/1055987
