I have a treeview,in which when iam selecting a child node..iam getting the text of child node as alert message using

var obj = window.event.srcElement;
         if (obj.tagName == "A")
{
          alert(obj.innerHTML);
}

Now I want the full heirarchy as ParentNode->SubNode->ChildNode in an alertmessage in javascript..

Solution 1

Try something like:

C#

function traverseElements(elem)
{
  alert(elem.innerHTML);
  for (i=0; i<elem.elements.length; i++)
  {
    traverseElements(elem.elements(i));
  }
}

Good luck!

You would just have to concatenate everything and add an indent parameter, something like the code below.

C#

function test()
{
  alert(traverseElements(startElement, ''));
}


function traverseElements(elem, indent)
{
  var result = indent + elem.innerHTML + '\n';
  for (i=0; i<elem.elements.length; i++)
  {
    result += indent + traverseElements(elem.elements(i), indent + ' ');
  }
  return result;
}

Good luck!
