This will get you what you need...

$(function() {
    $(".ShareFB").on("click", function() {
        var $div = $(this).closest(".Actions").prev();
        alert($div.attr('id'));
    });
});

closest() will parse back up the DOM tree until it finds the first instance of an element with the class Actions and then prev() will select the previous element. $div will then be a jQuery object that you can use as you wish.

Edit

I've updated your fiddle...

One problem was the call to ShareFB which was stopping the rest of the script running, and I fixed my previously incorrect code as well.

これを試して：

$('.ShareFB').click(function(){
        alert($(this).parent().parent().prev().attr("id"));
    });

再帰を使用する必要があります。

function getTargetParent(node){
if($(node).attr('class')=='Actions'){
    alert($(node).prev().attr('id'));
}
 getTargetParent($(node).parent());
return;
}

 var targnode=$('.Actions').find('.ShareFB');//replace with $(this) in real scenario
 getTargetParent(targnode);
