 设置数据源动态通过调用一个服务(ajax调用)

function myTreeInit() {

            $('#myTree').tree({
                dataSource: function(parentData, callback){
                    setTimeout(function () {
                        var id = (parentData!=undefined&&parentData!=null&&parentData.attr!=undefined)?parentData.attr.id:1;
                        var data = initTree(WEB_GLOBAL_CTX+"/console/security/organization/findJsonById/"+id,"",[3,4]);
                        callback(data);
                    }, 400);
                },
                multiSelect: true,
                cacheItems: true,
                folderSelect: false
            });
        }

//初始化fuelue树
function initTree(ajaxUrl, ajaxDataParam, initData) {
    //同步
    var temp_tree_data = {data:[]};
    $.ajax({
        async: false,
        cache: true,
        type: 'POST',
        url: WEB_GLOBAL_CTX + ajaxUrl,
        data: ajaxDataParam,
        error: function () {// 请求失败处理函数
            //$.scojs_message("更新失败,请重新登陆!", $ERROR);
        },
        success: function (result) {
            $(result.data).each(function () {
                var t = selectTreeOption(this,initData);
                temp_tree_data.data.push(t);
            });
        }
    });
    return temp_tree_data;
}
//下拉框选中

                obj.attr.className = select_class_name;
                obj.attr.dataIcon=selected_item_data_icon;
                return obj
