            };
        }
    }   
})();

我不能折叠（折叠）注解和函数，但如果我使用以下代码：

/**

    * @brief this file contains the basics of the frame work 
    *
    * @author David Garcia
    *
    * @date 11/08/1983
    */

window.onerror = function (sMessage, sUrl, sLine) {
            alert("An error occurred at " + sUrl + "\nLine Number: " + sLine + '\n\n' + sMessage);
            return true;
        };

        /**
         * IE fix
         */
        function ieFix(){
            if(typeof window.XMLHttpRequest === 'undefined' &&
                typeof window.ActiveXObject === 'function') {
                window.XMLHttpRequest = function() {
                    try { return new ActiveXObject('Msxml2.XMLHTTP.6.0'); } catch(e) {}
                    try { return new ActiveXObject('Msxml2.XMLHTTP.3.0'); } catch(e) {}
                    return new ActiveXObject('Microsoft.XMLHTTP');
                };
            }
        }

是错误或配置错误。
