I'm using jsTree plugin to display tree. The tree is loaded using ajax to a div with ul-li structure. And here is how I initialize it.

$("#jseq_tree").jstree({
      "core" : { "check_callback" : true},
      "plugins" : ["dnd","wholerow"]
}).jstree("open_all");

I'm trying to get all nodes from the tree on a button click like that:

$(document).on("click", "#sub_tree", function() {
    var v =$('#jseq_tree').jstree('get_json', -1);
    var mytext = JSON.stringify(v);
    alert(mytext);
});

But it always alerts false. How can I make it work? Or how can I get all elements of the tree with their ids and children?

That is some old code you are using. Instead of this:

$('#jseq_tree').jstree('get_json', -1

);

Use this:
$('#jseq_tree').jstree('get_json');

Best regards,
Ivan
