Backstretch copy output from loop to a DIV

I have a full screen background slideshow powered by the Backstretch script. I'm trying to create a caption for each slide and would like to display the information in 

<span class="cap"></span>

inside of 

<div class="caption"></div>

The span is part of a list that populates the slideshow and is hidden.

Here is a jsfiddle of what I have so far.

Thanks for any advice or help.

Solution

  • You can use the backstretch.show event as you suggest in you fiddle like a get the cap element array.

    Backstretch will fire a "backstretch.show" event everytime a new image loads, triggering a function that is passed the event and Backstetch instance. If you listen for that event, you can, for example, coordinate other changes to coincide with your slideshow.

    Code:

    // coordinating image captions with slides
$(b).on('backstretch.show', function() {
    $(this).data("backstretch").index;
    $(".caption").html(cap[$(this).data("backstretch").index].html());
});
