zTree获取节点序号及判断是不是父子节点

//获取节点的位置
var treeObj = $.fn.zTree.getZTreeObj("serviceTree");
var nodes = treeObj.getSelectedNodes();
if (nodes.length > 0) {
nodenum = treeObj.getNodeIndex(nodes[0]);
}

var treeObj = $.fn.zTree.getZTreeObj("serviceTree");
var nodes = treeObj.getSelectedNodes();
//判断选中的是否为子节点
//若为父节点flag = true
if(nodes.length > 0){
var flag = nodes[0].isParent;
}
