js获取当前日期，并且转化为时间格式“yyyy-MM-dd HH:MM:SS”

getDate: function () {
        var date = new Date();
        var seperator1 = "-";
        var seperator2 = ":";
        var month = date.getMonth() + 1;
        var day = date.getDate();
        var hours = date.getHours();
        var minutes = date.getMinutes();
        var seconds = date.getSeconds();
        if (month >= 1 && month <= 9) {
            month = "0" + month;
        }
        if (day >= 0 && day <= 9) {
            day = "0" + day;
        }
        if (hours >= 0 && hours <= 9) {
            hours = "0" + hours;
        }
        if (minutes >= 0 && minutes <= 9) {
            minutes = "0" + minutes;
        }
        if (seconds >= 0 && seconds <= 9) {
            seconds = "0" + seconds;
        }
        var currentdate = date.getFullYear() + seperator1 + month + seperator1 + day + " " + hours + seperator2 + minutes + seperator2 + seconds;
        console.log(currentdate)
        return currentdate;
    },
