I have been selected a node in jstree. I can get a json value of the selected nodes. But the problem is, I want the parent nodes of the child node , upto root

You can do this with the code as below. Check demo - Fiddle.

   function getParentNode(node) {
       return $('#tree').jstree().get_parent(node);
   }

   var nodes = $('#tree').jstree().get_selected('full'), parentNodes = [], parentTexts = [];

   nodes.forEach( function(node) {
      var parentNode = getParentNode(node);
      while (parentNode && parentNode !=='#') {
            if (parentNodes.indexOf(parentNode) === -1 ) { 
              parentNodes.push( parentNode );
              parentTexts.push( $('#tree').jstree().get_node(parentNode).text );
          }
          parentNode = getParentNode(parentNode);
      }
 })

UPDATE

The code you use could look like:

var checked_ids = [], checked_ids1 = [];
$("#temporary1").find(".jstree-undetermined").each(
    function(i, element) {
        var nodeId = $(element).closest('.jstree-node').attr("id");
        // alert( nodeId );
        checked_ids.push( nodeId );
        checked_ids1.push( $('#temporary1').jstree().get_node( nodeId ).text );
    }
);
