I hope it's not a problem to post much specific code here, but I figure it will be better explained if everyone can just see it, so I will give you my code and then I will explain my problem.

My code: 

function addBeGoneLinks () {
     var beGoneClassElems;
     var beGoneSpan;
     var beGoneLink;
     var beGonePrintSafe;
     var spacesSpan;
     //var middotSpan = document.createElement ('span');

     var interactionContainer = document.getElementsByClassName('feedItemInteractionContainer');

     for (var i=0; i<children.length; i++)
     {
         beGonePrintSafe = false;

         beGoneClassElems = children[i].getElementsByClassName('beGone')

         beGonePrintSafe = true;


         if (beGoneClassElems.length == 0)
         {
             beGoneLink = document.createElement('a');
             beGoneLink.href = 'javascript:void(0);';
             beGoneLink.appendChild(document.createTextNode('Be Gone'));
             beGoneLink.className = 'beGone';
             beGoneLink.id = 'beGoneLink' + i.toString();
             beGoneLink.addEventListener ("click", function() {beGone();}, false);//This line!
             beGoneLink.align = 'right';

             spacesSpan = document.createElement('span');
             spacesSpan.innerHTML = ' - ';

             if (interactionContainer[i] != undefined)
             {
                 interactionContainer[i].appendChild(spacesSpan);
                 interactionContainer[i].appendChild(beGoneLink);
             }
         }
     }
}

Here I have a function from a Greasemonkey script that I am working on. When one of the links is clicked, my aim is to have it call the function beGone() which will, among other things, remove the whole element a few parents up, thereby removing their sibling's, their parents and their parents' siblings, and one or two levels after that.

My idea was just to get the id of the link that was pressed and pass it to beGone() so that I could then get the parents using its id, but I do not know how to do that. Am I able to have the id of a link passed by the function that it calls? If not, is there any other way to do this?

I am not sure whether I am missing some really simple solution, but I haven't been able to find one rooting around the web, especially because I was unsure how I would search for this specific problem.

これを試して：

beGoneLink.addEventListener("click", beGone, false);

beGone = function (evt) {
    evt.target; // evt.target refers to the clicked element.
       ...
}


evt.target.idその後、、、evt.target.parentNodeなど を使用できます。
