order the selected (and undetermined) nodes

[Gopal Peddinti]

Hi,

I need to export selected nodes (and their undetermined parents). I am able to get the selected and undetermined nodes as needed, but I want to get these nodes in the tree order. Here is my current code.

$('#exportbutton').on('click', function() {
    // get the ids of the selected nodes. // false causes only the ID to be returned
    var selectedNodes = $('#myjstree').jstree('get_selected', false);

    var selectedAndUndetermined = [];
    for(i = 0; i < selectedNodes.length; i++) {
      // collect the ids of the selected nodes along with their parents
      selectedAndUndetermined = selectedAndUndetermined.concat($('#myjstree').jstree('get_path', selectedNodes[i], false, true));
    }
    // remove duplicates (i.e. create an array with unique elements)
    selectedAndUndetermined = Array.from(new Set(selectedAndUndetermined));

    // create the selected subtree (the combination of selected and undetermined nodes)
    var subtree = [];
    for(j = 0; j < selectedAndUndetermined.length; j++) {
       nodei = $('#myjstree').jstree('get_node', selectedAndUndetermined[j], false);
       subtree = subtree.concat(nodei);
    }

    console.log(subtree);

Could you please advise how to get nodes in `subtree`  in the same order in which they appear in the tree?

Thank you very much.

Best regards,

Gopal

I found a similar post in the forum https://groups.google.com/forum/#!searchin/jstree/order$20selected$20nodes%7Csort:date/jstree/oeaADRK5j50/ln6cHF415eYJ.

In my case, however, the json data is in the (id, parent) format (i.e. no node.children element).

In my case, however, the json data is in the (id, parent) format (i.e. no node.children element).

Sorry, this was just my misunderstanding apparently. I got the correct order with the logic given in the post I referred to (https://groups.google.com/forum/#!searchin/jstree/order$20selected$20nodes%7Csort:date/jstree/oeaADRK5j50/ln6cHF415eYJ). My code is below:

$('#exportbutton').on('click', function() {

    // get the ids of the selected nodes. // false causes only the ID to be returned

    var selectedNodes = $('#myjstree').jstree('get_selected', false);

    var undeterminedNodes = $('#myjstree').jstree('get_undetermined', false);

    var selectedAndUndetermined = selectedNodes.concat(undeterminedNodes);

    console.log('selected and undetermined', selectedAndUndetermined);

    var jsonFullTree = $('#myjstree').jstree('get_json', '#', { 'flat' : true });

    const subTree = jsonFullTree.filter((mynode) => selectedAndUndetermined.includes(mynode.id));

    console.log('subtree', subTree);
