javaScript获取当前时间

获取当前时间的函数一：

    function formatDate(time){
        let date = new Date(time);
        let year = date.getFullYear();
        // 在日期格式中，月份是从0开始的，因此要加0，使用三元表达式在小于10的前面加0，以达到格式统一  如 09:11:05
        let month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
        let day = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
        let hours = date.getHours() < 10 ? "0" + date.getHours() : date.getHours();
        let minutes = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes();
        let seconds = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();
        // 拼接
        return year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds;
    }

获取当前时间的函数二：

    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;
}
