时间格式转化

1.时间戳格式转化

formatDateTime(new Date(这里输入时间戳));

var formatDateTime = function (date) {
    var y = date.getFullYear();
    var m = date.getMonth() + 1;
    m = m < 10 ? ('0' + m) : m;
    var d = date.getDate();
    d = d < 10 ? ('0' + d) : d;
    // var h = date.getHours();
    // h=h < 10 ? ('0' + h) : h;
    // var minute = date.getMinutes();
    // minute = minute < 10 ? ('0' + minute) : minute;
    var second = date.getSeconds();
    second = second < 10 ? ('0' + second) : second;
    return y + '-' + m + '-' + d;
};
