jstree通过前台js生成了树,但是没有链接,js代码如下 $(function() {
            $("#demo0").bind('loaded.jstree', function(e, data) {
                // invoked after jstree has loaded
                $('#demo1>ul>li').addClass('topMenu');
            }).jstree({
            "themes": { "theme": "classic" },
                "json_data": {
                    "ajax": {                        "type": "POST",
                        "dataType": "json",
                        "contentType": "application/json;",
                        "url": "/Desktop/MenusFunc.aspx/GetAllNode",
                        "data": function(node) {
                        if (node == -1) {
                            return '{ "operation" : "get_children", "parentId" : ' + 1 + '}';
                        } else {
                            return '{ "operation" : "get_children", "parentId" : ' + $(node).attr("id") + '}';
                        }
                        },
                        "success": function(retval) {                            return retval.d;                        }
                    }
                },
                "plugins": ["themes", "json_data"]
            });
        });后台生成的json格式如下,存在href的属性但是在最终生成的节点代码没有链接的属性,<a href="#"><ins class="jstree-icon">&nbsp;</ins>Claim Summary</a>想请教下这是为什么?
