Title Body

I wish to replace the entire contents of a jstree tree with new json data. I'm using jsTree 1.0 downloaded July 25, 2011 from github Say I have this function... function init_my_tree(my_json_data) { $("#demo1").jstree({ themes: { "theme": "classic", "dots": false, "icons": true, "url": "//js.myliburl.com/jstree/themes/classic/style.css" }, json : { data : my_json_data }, plugins : [ "core","ui","themes", "json" ] }); } where demo1 refers to a <div id="demo1"></div> What I'm trying to do is to completely replace the tree with new data that I load from my server. For purposes of this question, however, let's pretend I just want to do this... $(document).ready(function() { var text_data = '[{"title":"All","data":{"jstree":{"opened":true}},"children":[{"title":"Item 1","data":{"jstree":{}},"children":false,"li_attr":{"id":"1","class":"jstree-leaf","href":"#"},"a_attr":{"href":"#"}},{"title":"Item B","data":{"jstree":{}},"children":false,"li_attr":{"id":"2","class":"jstree-last","href":"#"},"a_attr":{"href":"#"}}],"li_attr":{"id":"0","class":"jstree-last","href":"#"},"a_attr":{"href":"#"}}]'; var my_json_data = $.parseJSON(text_data); init_my_tree(my_json_data); // initialize the tree view text_data = '[{"title":"Something Else","data":{"jstree":{"opened":true}},"children":[{"title":"Item A","data":{"jstree":{}},"children":false,"li_attr":{"id":"1","class":"jstree-leaf","href":"#"},"a_attr":{"href":"#"}},{"title":"Item 2","data":{"jstree":{}},"children":false,"li_attr":{"id":"2","class":"jstree-last","href":"#"},"a_attr":{"href":"#"}}],"li_attr":{"id":"0","class":"jstree-last","href":"#"},"a_attr":{"href":"#"}}]'; my_json_data = $.parseJSON(text_data); init_my_tree(my_json_data); // re-initialize the tree view to load with new data }); I'm doing this based on this l
