jsTree Open a branch

Question

I am using the JQuery plugin jsTree, http://www.jstree.com/ I am able to expand the whole tree with the following method:

$(\"#tree\").jstree(\"open_all\");


        

Answer 1

Here is function that can open a specific node and all its parents.

function expandNode(nodeID) {
    // Expand all nodes up to the root (the id of the root returns as '#')
    while (nodeID != '#') {
        // Open this node
        $("#jstree").jstree("open_node", nodeID)
        // Get the jstree object for this node
        var thisNode = $("#jstree").jstree("get_node", nodeID);
        // Get the id of the parent of this node
        nodeID = $("#jstree").jstree("get_parent", thisNode);
    }
}

Answer 2

just use this if you use json

$("#treeId").on
('loaded.jstree', function() {
 $("#treeId").jstree("open_node", $("#nodeId"));
 });
