js获取当前时间并格式化

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;

}
