ztree 异步加载 点击展开出现undefined

Question

点击boot展开

在console打印的是：

是index.html的内容

数据格式：

{
id":"0-null-0-/",
"name":"本地磁盘文件",
"absoluteName":"/",
"level":0,
"type":0,
"parentId":null,
"host":null,
"isParent":null,
"children":[{"id":"bin/","name":"bin/","absoluteName":"/bin/","level":1,"type":0,"parentId":"","host":null,"isParent":false,"children":null},
{"id":"boot/","name":"boot/","absoluteName":"/boot/","level":1,"type":0,"parentId":"","host":null,"isParent":true,"children":null},
{"id":"data1/","name":"data1/","absoluteName":"/data1/","level":1,"type":0,"parentId":"","host":null,"isParent":false,"children":null},
]
}

  var tree = {
    zTree:'',
    pNode:'',
    setting : {
      showLine : true,                  //是否显示节点间的连线

      absoluteName: treeNode.absoluteName
    };
    //获取parentId = id的数据，也就是子节点的id等于父节点的id，说明此父节点加载了子节点
    if(!zTree.getNodeByParam("parentId",treeNode.id)){
      BackupService.getDataSource(parameter).then(function(result){
        /**
         * 把查询出来的字节点追加到父节点上
         */
        var tempData = [];
        if(result.data.data.children.length>0) {
          zTree.addNodes(treeNode,result.data.data.children,true);
          var nodeTrees = treeNode.children;
          for(var j=0,len1=nodeSource.length;j<len1;j++){
            for(var i=0,len=nodeTrees.length;i<len;i++) {
              if(nodeTrees[i].bsoluteName===nodeSource[j]){
                nodeTrees[i].checked = true;
              }
            }
          }
        } else {
          return;
        };

      }, function(msg){
        console.log(msg);
      });
    }
  }
