JS 生成yyyymmddhhmmss这样的字符串

function pad2(n) { return n < 10 ? '0' + n : n }
 
function generateTimeReqestNumber() {
    var date = new Date();
    return date.getFullYear().toString() + pad2(date.getMonth() + 1) + pad2(date.getDate()) + pad2(date.getHours()) + pad2(date.getMinutes()) + pad2(date.getSeconds());
}

	//生成时间yyyymmdd
		 var nowDate = new Date();
		 var year = nowDate.getFullYear();
		 var month = nowDate.getMonth() + 1 < 10 ? "0" + (nowDate.getMonth() + 1)
		  : nowDate.getMonth() + 1;
		 var day = nowDate.getDate() < 10 ? "0" + nowDate.getDate() : nowDate.getDate();
		 var dateStr = year + "-" + month + "-" + day;

	console.log(dateStr);
