How to get the parent div?

[Sharon whipple]

Hi ranchers,
I am working on JS TreeView control.
I am trying to get the parent div id of the current node selected:

<div id="tree-1" >
        <a href="javascript:promptDivId(this,'label');" id="tree-1-anchor">1</a>
</div>

How can I get wrapping div object or Div id (tree-1) from within promptDivId function?

promptDivId :

function promptDivId(obj,str){
      alert(obj.parent.id);
}

Thank you.


Tree code:

<div id="tree-0"  >
  <img id="tree-0-icon"  >
  <a href="javascript:promptDivId(this,'label');" id="tree-0-anchor">Root</a>
</div>
<div id="tree-0-cont" class="-tree-container" style="display: block;">
  <div id="tree-1" >
    <img id="tree-1-plus" >
    <img id="tree-1-icon"  >
    <a href="javascript:promptDivId(this,'label');" id="tree-1-anchor">1</a>
  </div>
  <div id="tree-2" >
    <img id="tree-2-plus" >
    <img id="tree-2-icon"  >
    <a href="javascript:promptDivId(this,'label');" id="tree-2-anchor">2</a>
  </div>
  <div id="tree-3" >
    <img id="tree-3-plus" >
    <img id="tree-3-icon"  >
    <a href="javascript:promptDivId(this,'label');" id="tree-3-anchor">3</a>
  </div>
</div>
