单击轮播glyphicon时如何获取数据ID

Question

I need to grab an id, but it is in a slider and the only click event I get access to is the arrows, but they cannot take the unique id of the image. I know there must be a way traverse to the div but that is a little out of my league right now. I did try anything that I found or that came to me but have been unsuccessful so far.

The code for the slider

<div id="myCarousel" class="carousel slide fluid col-md-6 col-md-offset-3" data-ride="carousel" style="height:95%;background-color: #000;">
  <ol class="carousel-indicators">
    <li data-target="#myCarousel" data-slide-to="0" class="active" style="border:1px solid #febe27;margin-bottom:125px;"></li>
    {% for storyItem in craft.entries.section('stories').find() %}
    {% for previewImage in storyItem.slideshowImage %}  
      <li data-target="#myCarousel" data-slide-to="1" style="border:1px solid #febe27;margin-bottom:125px;"></li>
   {% endfor %}  
   {%endfor%}
</ol>

<div class="carousel-inner" role="listbox" style="height:87%;position:relative;">
  <div class="item active">
    {% for storyItem in craft.entries.section('stories').limit(1) %}
     {% for previewImage in storyItem.slideshowImage %}  
    <div id="{{storyItem.id}}" class="imgContentWrapper 1" data-id="{{storyItem.id}}"><a href="#"><img src="{{ previewImage.url('slideshowImage') }}" alt="" border="0" /></a>
    </div>
    {% endfor %}
  {%endfor%}
</div>

{% for storyItem in craft.entries.section('stories').offset(1) %}
{% for previewImage in storyItem.slideshowImage %}  
  <div class="item ">
    <div id="{{storyItem.id}}" class="imgContentWrapper" data-id="{{storyItem.id}}"><a href="#"><img src="{{ previewImage.url('slideshowImage') }}" alt="" border="0" /></a>
    </div>
  </div>
  {% endfor %} 
  {%endfor%}
 </div>

 <a class="left carousel-control" href="#myCarousel"  role="button" data-slide="prev">
  <span class="glyphicon glyphicon-chevron-left" aria-hidden="true" style="margin-left:-25px;"></span>
  <span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel"  role="button" data-slide="next">
  <span class="glyphicon glyphicon-chevron-right" aria-hidden="true" style="margin-right:-25px;"></span>
  <span class="sr-only">Next</span>
</a>

I am trying to grab the {{ storyItem.id }} in the divs (there is two the active and the regular item) on the glyphicon 'click'.

Any help is greatly appreciated.

Answer 1

This should do the trick mate...

$('.glyphicon-chevron-left, .glyphicon-chevron-right').on('click', function() {
    var id = $('.carousel-inner').find('item.active').find('.imgContentWrapper').data('id');
});

Answer 2

I suppose that a.carousel-control are in the same #myCarousel div as your images. If so you can traverse to the parent and find the image you want like this:

$('.carousel-control').on('click', function() {
    var imageId = $(this).parent().find('#your_image_selector');
});
