从中调用函数的链接的id [英] id of a link that a function is called from

问题描述

我希望在这里发布更具体的代码不是问题，但我认为如果每个人都能看到它会更好地解释，所以我会给你我的代码然后我会解释我的问题。

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.

我的代码：

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);
             }
         }
     }
}

这里我有一个我正在研究的Greasemonkey脚本的函数。当点击其中一个链接时，我的目标是让它调用函数 beGone（）除其他外，将删除几个父母的整个元素，从而移除他们的兄弟姐妹，他们的父母和他们的父母的兄弟姐妹，以及之后的一两个级别。

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.

我的想法只是获取被按下的链接的ID将它传递给 beGone（），这样我就可以使用它的id获取父母，但我不知道该怎么做。我能够通过它调用的函数传递一个链接的id吗？如果没有，有没有其他方法可以做到这一点？

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?

我不确定我是否缺少一些非常简单的解决方案，但我找不到一个扎根于网络，特别是因为我不确定如何搜索这个特定的问题。

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.

推荐答案

试试这个：

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

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

你可以然后使用 evt.target.id ， evt.target.parentNode 等。
