问题描述

我知道我可以获取单个ID的元素.

I know I can grab the element of an individual ID.

是否可以将侦听器附加到父div并传递被单击的单个范围的ID?

Anyway I can attach a listener to the parent div and pass the ID of the individual span that was clicked?

<div id = "divId">
  <span id="one"></span>
  <span id="two"> </span>
 </div>

JS

document.getElementById("two").addEventListener("click", someFunction);

推荐答案

您可以使用event对象并访问其target属性

You can use the event object and access its target property

document.getElementById("divId").addEventListener("click", someFunction);

function someFunction(event) {
  console.log(event.target.id);
}
<div id="divId">
  <span id="one">one</span>
  <span id="two"> two</span>
</div>
