JavaScript：获取系统当前时间，构造格式化的字符串

var getNowFormatDate = function() {
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 hours = date.getHours();
if (hours >= 0 && hours <= 9) {
hours = "0" + hours;
}
var minutes = date.getMinutes();
if (minutes >= 0 && minutes <= 9) {
minutes = "0" + minutes;
}
var seconds = date.getSeconds();
if (seconds >= 0 && seconds <= 9) {
seconds = "0" + seconds;
}
var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
+ " " + hours + seperator2 + minutes+ seperator2 + seconds;
return currentdate;
};
