jstree 异步加载 默认只能解析固定格式的返回值 利用回调来处理服务器返回的数据,

1. 默认只能解析固定格式的返回值
   $('#red-ui-networktree-body')
   .jstree({
   "plugins": ["contextmenu", "search", "json_data", "sort", "themes"],
   'core': {
   'data': {
   "url": networktreeurl,
   "data": function (node) {
   return { "archive": "archive1", "reference": node.id };
   },
   "success": function (nodes) {
   callBackBuildingSpaceTree(nodes);
   }
   }

   },
   "sort": function (prevEle, currentEle) {

   },
   "contextmenu": { // disable the context menu, the "contextmenu" plugin is only
   "items": {} // needed for the context menu / right click event
   },
   "themes": {
   "theme" : "default",
   "dots" : true,
   "icons": true
   },
   }).on('ready.jstree', function (e, data) {
   renderOSPoint();
   }).on("open_node.jstree", function (e, data) {
   renderOSPoint();
   });
