Fancybox 2 Dynamic Width Based on Content Size

jquery iframe dynamic fancybox sizing

Solution 1

Looking at your intro-file.cfm file makes things clearer.

If your code inside the file is working fine, I think that you could get the dimensions from the preview_wrapper container.

Just two questions:

if you are using $ ... in $('.loading-video').slideUp() for instance, shouldn't you be including the jquery.js file inside your intro-file.cfm file?
is this double ## before the selector in $('##preview_wrapper').width() correct?

Assuming that everything is working fine, then try including in your fancybox script:

  scrolling: "no", // optional to avoid scrollbars inside fancybox
  beforeShow: function(){
   this.width = $('.fancybox-iframe').contents().find('#preview_wrapper').width();
   this.height = $('.fancybox-iframe').contents().find('#preview_wrapper').height();
  }

... to get the dimensions from the player's wrapper.

Solution 2

Iframe width is currently not calculated. Maybe you could set width/height for each iframe like this - http://jsfiddle.net/vVKMF/

I've got an IFrame being opened via Fancybox 2 that plays a video:

HTML:

<a class="fancybox-video" href="/user/intro-file.cfm" rel="file_name" title="View Video">File Name</a>

Javascript:

$("a.fancybox-video").fancybox({
    scrolling   : 'no', 
    type        : 'iframe', 
    helpers     : { 
        title: null 
    }
});

The video is user-uploaded, so I don't know the size. I will be setting a maxHeight and maxWidth on the Fancybox eventually, but I've removed them for easier troubleshooting.

How can I set the width of the Fancybox based on the content? With my test file, which is around 400px wide, the fancybox itself is being set to 830/800px wide (the outer and inner widths): screencap of too-wide fancybox http://img528.imageshack.us/img528/3872/fancyboxwidth.png

autoSize and fitToView have no effect. There's no CSS or code on the IFrame page that is setting a default width. If I force a width in the Fancybox code it works, but since my content is dynamic, it won't work for the live system.

I also tried adapting a function from another question asking about height resizing, but it didn't work either:

beforeShow  : function() { 
    $('.fancybox-iframe').load(function() { 
        $('.fancybox-inner').width($(this).contents().find('body').width()); 
    }); 
}

Edit: Added the code of the IFrame page I'm trying to load into the Fancybox:
