captions in own div outside of slider

问题

I am using the bxslider. It works very well for me, but I have 1 problem. I want the captions outside of the bxwrapper.

The html of the slider looks like this only the div captions is created by me

            <div class="captions"></div>
            <ul class="bxslider">
              <li><img src="images/1.jpg" title="headline, text" /></li>
              <li><img src="images/1.jpg" /></li>
              <li><img src="images/1.jpg" title="text" /></li>
              <li><img src="images/1.jpg" title="text" /></li>
            </ul>

The captions are generated out of the title from the images with this code:

* Appends image captions to the DOM
     */
    var appendCaptions = function(){
        // cycle through each child
        slider.children.each(function(index){
            // get the image title attribute
            var title = $(this).find('img:first').attr('title');
            // append the caption
            if (title != undefined && ('' + title).length) {
                $(this).append('<div class="bxcaptions"><span>' + title + '</span></div>');
            }
        });
    }

i tried to style the captions that they are outside of the slider, but the slider uses overflow hidden and so its impossible.

So i want that the captions are written into the <div class="captions"></div> which i can position the way i want it.

Further i maybe want that the headline before the , is highlighted with h1 and the rest is normal but thats just additional.

Thanks for your help!

Here the jsbin: http://jsbin.com/ikokex/3

jquery:

var captionText = '';    
$('ul.bxslider > li > img').each(function(i,e) {
  var titleAttr = $(this).attr('title');
  if(typeof titleAttr != 'undefined') {
     var captionSplit = titleAttr.split(',');
     $('.captions').append('<div class="caption-'+i+'"></div>');
     if (captionSplit.length > 1) {
       captionText += '<h1>'+captionSplit[0]+'</h1>';
       captionText += '<span>'+captionSplit[1]+'</span>';
     } else {
       captionText += '<span>'+captionSplit[0]+'</span>';
     }
     $('.caption-'+i).html(captionText);
     captionText = '';
  }
});

i think i have a solution but its very dirty! i insert this code $('.captions').html(slider.children.eq(slider.active.index).find('img:first').attr('title'));

at the end of the slide function in the jquery.bxslider.js line 1188.

if somebody has a better solution please let me know!

  prependtxt: 'Examples  ',
  pagerType: 'short',
  mode: 'fade',
  auto: true,
  onSliderLoad: function(currentIndex) {
    $(".slider-txt").html($('.bxslider li').eq(currentIndex).find("img").attr("title"));
  },
  onSlideBefore: function($slideElement, oldIndex, newIndex) {
    $(".slider-txt").html($slideElement.find("img").attr("title"));
