<script>
function getNowDate() {
var date = new Date();
var sign1 = "-";
var sign2 = ":";
var year = date.getFullYear() // 年
var month = date.getMonth() + 1; // 月
var day = date.getDate(); // 日
var hour = date.getHours(); // 时
var minutes = date.getMinutes(); // 分
var seconds = date.getSeconds() //秒
var weekArr = ['星期一', '星期二', '星期三', '星期四', '星期五', '星期六', '星期天'];
var week = weekArr[date.getDay()];
// 给一位数数据前面加 “0”
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (day >= 0 && day <= 9) {
day = "0" + day;
}
if (hour >= 0 && hour <= 9) {
hour = "0" + hour;
}
if (minutes >= 0 && minutes <= 9) {
minutes = "0" + minutes;
}
if (seconds >= 0 && seconds <= 9) {
seconds = "0" + seconds;
}
var currentdate = year + sign1 + month + sign1 + day + " " + hour + sign2 + minutes + sign2 + seconds + " " + week;
return currentdate;
}
console.log(getNowDate());
</script>
</body>
