What do you mean by "attaching Javascript"? Do you want to override the behavior of the particular node when it's being clicked? Is so, try the following approach:

protected void Page_PreRender(object sender, EventArgs e)
{
    foreach (TreeNode rootNode in myTreeView.Nodes)
    {
        ExamineTreeNode(n);
    }
}

private void ExamineTreeNode(TreeNode n)
{
    if (n.ChildNodes.Count > 0)
    {
        n.NavigateUrl = "javascript:alert('Has children!')";
        foreach (TreeNode child in n.ChildNodes)
        {
            ExamineTreeNode(child);
        }
    }
}

Hope this is what you needed.
