JS获取"yyyy-MM-dd HH:mm:ss"格式的时间，其代码如下：

function getFormatDate() {
var date = new Date();
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() + "-" + month + "-" + strDate
+ " " + date.getHours() + ":" + date.getMinutes() + ":" + date.getSeconds();
return currentDate;
}
