JS获取当前日期时间

1.YYYY-MM-DD

function formatDate(date, pattern) {
if(typeof pattern == ‘undefined‘){
pattern = ‘yyyy-MM-dd‘;
}

var str = ‘‘;
if (date instanceof Date) {
var year = date.getFullYear();
var month = date.getMonth() + 1;
if (month <= 9) {
month = ‘0‘ + month;
}
var day = date.getDate();
if (day <= 9) {
day = ‘0‘ + day;
}
str = pattern.replace(‘yyyy‘, year).replace(‘MM‘, month).replace(‘dd‘, day);
}

return str;
}

2. YYYY-MM-DD HH-MM-SS

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;
}
