The easiest way to generate date and time with JavaScript

2017. 10. 20. 12:31

JavaScript

Date

Time

Function

I made a little script to generate date and time with JavaScript. It's very simple and you can easily customize it.

First we generate the Date object.

var ctime = new Date(); // Generate the Date()

After this, we have to get the necessary parts of it. At some parts we need to make some changes to get a nice result. If the variable is one character long, we add an extra 0 to it. Here is the Year block:

var month = ctime.getMonth() + 1;
if (month < 10){
	month = "0" + month; // If the variable is one character long, we add an extra 0 to it.
}

We need to repeat it at the Days, Hours, Minutes and Seconds.

Finally, we have to append the variables. You can easily change the format, by modifying the separating characters. Lastly, convert the return variable to String.

// We should append the variables, to get a full date and time.
var now_date = year + '. ' + month + '. ' + day + '. ' + hour + ':' + min + ':' + sec;

return String(now_date); // The functions returns with the date and time. We should convert it to String.

Here is the whole source code:


function now_date(){
	var ctime = new Date(); // Generate the Date()
	
	var year = ctime.getFullYear();
	
	var month = ctime.getMonth() + 1;
	if (month < 10){
		month = "0" + month; // If the variable is one character long, we add an extra 0 to it.
	}
	
	var day = ctime.getDate();
	if (day < 10){
		day = "0" + day;
	}
	var hour = ctime.getHours();
	if (hour < 10){
		hour = "0" + hour;
	}
	
	var min = ctime.getMinutes();
	if (min < 10){
		min = "0" + min;
	}
	
	var sec = ctime.getSeconds();
	if (sec < 10){
		sec = "0" + sec;
	}
	
	// We should append the variables, to get a full date and time.
	var now_date = year + '. ' + month + '. ' + day + '. ' + hour + ':' + min + ':' + sec;

	return String(now_date); // The functions returns with the date and time. We should convert it to String.
}

Monty Hall problem
You are in a show. There are three doors and you have to select one door. Behind one door there is the prize: the car. Behind the two other doors you can only find a goat. The mission is simple: find the door which hides the car.
