Date.prototype.format = function(format){
    var o = {
        "M+" : this.getMonth()+1, //month
        "d+" : this.getDate(), //day
        "h+" : this.getHours(), //hour
        "m+" : this.getMinutes(), //minute
        "s+" : this.getSeconds(), //second
        "q+" : Math.floor((this.getMonth()+3)/3), //quarter
        "S" : this.getMilliseconds() //millisecond
    }
    if(/(y+)/.test(format)){
        format=format.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length)); 
    }
    for(var k in o){
        if(new RegExp("("+ k +")").test(format)){
            format = format.replace(RegExp.$1, RegExp.$1.length==1 ? o[k] : ("00"+ o[k]).substr((""+ o[k]).length));
        } 
    }
    return format;
}
