ztree中怎样获取选中节点的父节点及自己的index

Answer 1

ztree获取当前选中节点及所有父节点

获得当前选中节点路径，如部门库〉新闻部〉文字稿：

树如下图：

 js:

var curLocation="";//当前位置

var treeObj = $.fn.zTree.getZTreeObj("rs_tree");
var nodes = treeObj.getSelectedNodes();
if(nodes.length>0){
var allNode = nodes[0]['text'];//获取当前选中节点
var node = nodes[0].getParentNode();
getParentNodes(node,allNode);
}
var location = "";
var nodeArrs = curLocation.split(">");
for(var i=nodeArrs.length-1;i>=0;i--){
location += nodeArrs[i]+">";
}
location = location.substring(0, location.lastIndexOf(">"));
alert(location);

 

function getParentNodes(node,allNode){
if(node!=null){
allNode += ">"+node['text'];
curNode = node.getParentNode();
getParentNodes(curNode,allNode);
}else{
//根节点
curLocation = allNode;
}
}

 结果：location:  部门库>xx部>国内
