javascript - 如何通过事件目标获取上一个元素？

问题描述

我正在尝试div/ class/ wrapper/ container通过event.targetReact javascript 获取上一个。它是一张桌子，这是DOM树。当我单击带有“1”的单元格时，event.target 将输出

<div class="id">
  <span>1</span>
</div>

我怎样才能让它输出<div class="Table row">呢？谢谢

桌子：

id name location
1  test test      #the below html dom is for this row

DOM：

<div class="Table row" custom_att="test">
  <div class="id">
    <span>1</span>
  </div>
  <div class="name">
    <span>test</span>
  </div>
  <div class="location">
    <span>test</span>
  </div>
</div>

代码：

onMouseDownEvent(e){
    var ele = e.target;
    //do something with ele
}

  </div>
</div>
 <div id="log">
   
 </div>

$( "body" ).click(function( event ) {
 
  $( "#log" ).html( "clicked: " + event.target.parentNode.nodeName );
});
