Javascript 如何在单击时捕获div的id并将其传递给函数以使代码动态？

我有一个基于coffeescript的代码，其中包含所有定义，ID和类都在本地调用。现在，我希望它基于一个动态视图重构它，也就是说，当用户在站点中单击时，应该将相应的ID发送给函数。我该怎么处理

HTML-

<div id="dl1">
 <div class="dl_div">
  <div id="target1" data-key="<%= @aws_url1[:key] if !@aws_url1.nil? %>">
  <% if !@aws_url1.nil? %>
   <img id="user_dl1" src="<%= @aws_url1[:url] %>">
  <% end %>
 </div>
 <div id="close1" style="display: none;">
  <button id="closebtn1" class="closebtn">X</button>
 </div>
 <div id="closemsg1" style="display: none;  position: relative;">
  <button  id="deletebtn1" class="deletebtn">
   <p class="deletebtnstyle">Delete</p>
  </button>
  <button id="cancelbtn1" class="cancelbtn">
   <p class="cancelbtnstyle">Cancel</p>
  </button>
</div>
<div class="file_browser1" id="file_browser1">
  <label for="file_upload1" class="custom-file_upload z-depth-1">
   <i class="material-icons">&#xE147;</i>
   <p class="button-text"> Upload Here</p>
  </label>
<form id="user_id1_form" action="">
  <input type="hidden" name="user_id1_key" value="<%= @aws_urls[0][:key] %>"/>
  <input id="file_upload1" type="file" accept="image/*" name="user_id1"/>
 </form>
 </div>
 </div>
</div>

如何在单击时将ID传递给coffeescript？

如果我从您的问题中理解，您希望将单击事件添加到一组元素中，并在触发时能够获得它们各自的值

一种方法是将单击事件添加到属性类：

例如，使用jquery：

//将单击事件添加到类。钻取光标 $.drill\u cursor.clickfunction{ console.logthis.id； }; //用于显示console.log var consoleLine=

； 控制台={ 日志：函数文本{ $console log.append$consoleLine.htmltext； } }; .控制台线路{ 字体系列：monospace； 颜色：红色； 保证金：2倍； } .drill_光标{ 利润率：50像素； 颜色：蓝色； } div-1-click-on-me div-2-click-on-me div-3-click-on-me div-4-click-on-me

发送元素引用而不是id字符串不是更有意义吗？无论如何都很好。我只需要一个传递给函数的引用。我该怎么做？传递到哪个函数？@Satpal我想捕获HTML中的ID或元素引用到上述脚本中的咖啡脚本。如果我从您的问题中理解，您想获取页面中所有/大多数元素的事件吗？例如，对于页面中的任何按钮，当用户单击时，您应该获得元素引用吗？
