Parent/Closest Div Issue

EDIT: I have the following code:

<div class="specificBlock" id="thevagabond">
     <a class="intro"><img src="images/blabla.png"/></a> 
     </br>
     <div class="btn-group-xs testing">
        <a type="button" class="btn btn-success intro">Use</a>
     </div>
</div>

<div class="specificBlock" id="thedog">
     <a class="intro"><img src="images/blabla.png"/></a> 
     </br>
     <div class="btn-group-xs testing">
        <a type="button" class="btn btn-success intro">Use</a>
     </div>
</div>

My issue is the following: I'd like to find a jQuery/JavaScript way to get the ID of the div from which the clicked 'a' class="intro" comes from.

The problem here is that if the first a with class="intro" is clicked on, I would need to use the closest div's ID.

But if I click on the second the closest div is not the right one - the closest would be then the div with class="testing", which I don't want.

Is there any way to do this?

$("a").on("click", function (e) {
  $(this).parents("#thevagabond");
});

or as mentioned before #thevagabond directly.

EDIT:
Depending on the new information (see comments below) heres a new solution. You could either place the target URL for the iframe in the hrefof the a or add an data-attribute to either the a or one of its parents.

HTML:

<div class="specificBlock" id="thevagabond" data-url="my/iframe/url">
     <a class="intro"><img src="images/blabla.png"/></a> 
     </br>
     <div class="btn-group-xs testing">
        <a type="button" class="btn btn-success intro">Use</a>
     </div>
</div>

<div class="specificBlock" id="thedog">
     <a class="intro" href="my/iframe/url"><img src="images/blabla.png"/></a> 
     </br>
     <div class="btn-group-xs testing">
        <a type="button" href="my/iframe/url" class="btn btn-success intro">Use</a>
     </div>
</div>

<iframe id="my-frame" src="" width="500" height="500" style="display:none" />

JavaScript/jQuery:

var $specificBlocks = $(".specificBlock"),
    $thevagabond = $specificBlocks.filter("#thevagabond"),
    $thedog = $specificBlocks.filter("#thedog"),
    $iframe = $("#my-frame");

$thevagabond.on("click", "a", function (e) {
  e.preventDefault();
  $iframe.attr("src", $thevagabond.data("url"));
  $iframe.show();
});

$thedog.on("click", "a", function (e) {
  e.preventDefault();
  var $t = $(this),
      url = $t.attr("href");

  $iframe.attr("src", url);
  $iframe.show();
});

I would prefer the #thedog option because the page that will be shown in the iframe will be also accessable for non JS users and search engines.

ID should be unique, so you would do just $('#thevagabond'). However, you probably need to use .parents(selector_here) - check documentation.

If you really need ID, check this:

$('.specificBlock a').click(function(){
var id_that_you_looking_for = $(this).parents('.specificBlock').attr('id');
//code more
});
