标准时间格式怎么转换成2020-9-10 19:38:22 格式

changeFullTime(date) {
    var d = new Date(date);

    var datetime =
        d.getFullYear() +
        "-" +
        (d.getMonth() + 1) +
        "-" +
        d.getDate() +
        " " +
        d.getHours() +
        ":" +
        d.getMinutes() +
        ":" +
        d.getSeconds();
    // console.log(datetime);
    return datetime;
}
