The task is to print the system’s current day and time in the following format(Time in hours, minutes and milliseconds).
Approach:
Use getDay() function to create an array of days in a week. It returns a number of day like 0 for Sunday, 1 for Monday and so on). Convert it into AM or PM using ternary operator.
Use getHours() method to get the hour value between 0 to 23. It returns an integer value.
Minutes and milliseconds were printed using getMinutes() and getMilliseconds() functions respectively.
Example:
<!DOCTYPE html>
<html>
<head>
<title>
print current day and time
</title>
</head>
<body>
<script type="text/javascript">
var myDate = new Date();
var myDay = myDate.getDay();
// Array of days.
var weekday = ['Sunday', 'Monday', 'Tuesday',
'Wednesday', 'Thursday', 'Friday', 'Saturday'
];
document.write("Today is : " + weekday[myDay]);
document.write("<br/>");
// get hour value.
var hours = myDate.getHours();
var ampm = hours >= 12 ? 'PM' : 'AM';
hours = hours % 12;
hours = hours ? hours : 12;
var minutes = myDate.getMinutes();
minutes = minutes < 10 ? '0' + minutes : minutes;
var myTime = hours + " " + ampm + " : " + minutes +
" : " + myDate.getMilliseconds();
document.write("\tCurrent time is : " + myTime);
</script>
</body>
</html>
