function getNowFormatDate() {    var date = new Date();    var seperator1 = "-";    var seperator2 = ":";    var month = date.getMonth() + 1;    var strDate = date.getDate();    if (month >= 1 && month <= 9) {        month = "0" + month;    }    if (strDate >= 0 && strDate <= 9) {        strDate = "0" + strDate;    }    var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate            + " " + date.getHours() + seperator2 + date.getMinutes()            + seperator2 + date.getSeconds();    return currentdate;}
