How to get path of children when parent is selected in jstree

问题

I'm trying to get the path of the parent and children nodes when the parent is selected. To get the path of the node selected I did the following:

 $("#jstree_demo_div").jstree({
    "core" : {
       "data" : {
          "type" : "POST",
          "url" : "myurl.php",
          "data" : function (node) {
                  return { "id" : node.id };
              }
       },
       "dataType" : "json",
    },
    "plugins" : [ "wholerow", "checkbox", "types" ]
 })
 .on("changed.jstree", function (e, data) {
    var path = $("#jstree_demo_div").jstree(true).get_path(data.node,"/");
    console.log ("path = " + path + "\n");
 });""

But I don't know how to get the path the children's parent.

I tried to get the id's of children's parent and then apply the split()function to get the id's and then apply the get_path() but this is not working, because it said that split is not a function.

var test = data.node.children;
var spt_tst = test.split(',');
alert("node = " + spt_tst[0]);

What am I doing wrong?

**** EDIT ****

My tree is like in the image:

What I want to do is: select the folder images and the get the path of all the content, for example, I want to get the path of the things that are inside .xvpics folder and the others too. Because I will have to send these paths to an .txt file.

回答1:

data.node.childrenreturns an array, which you can access by index. To get the i-th element use data.node.children[i]. For example, to iterate over all children of data.nodedo this:

for (var i = 0; i < data.node.children.length; i++) {
  //for example call get_path of the child
  var path = $(\'#jstree_demo_div\').jstree(true).get_path(data.node.children[i],"/");
}

I hope I understood you right and that is what you are looking for.

EDIT: You can use children_d to get all children of the node. Even the children of the children.

for (var i = 0; i < data.node.children_d.length; i++) {
  //for example call get_path of the child
  var path = $(\'#jstree_demo_div\').jstree(true).get_path(data.node.children_d[i],"/");
}

Hope I got you right this time. Just let me know if not.
