The Date object is a data type built into the JavaScript language. Date objects are created with the new Date( ) as shown below.
Once a Date object is created, a number of methods allow you to operate on it. Most methods simply allow you to get and set the year, month, day, hour, minute, second, and millisecond fields of the object, using either local time or UTC (universal, or GMT) time.
The getMilliseconds() function of the Date object returns the milliseconds of its current date.
Its syntax is as follows
dateObj.getMilliseconds();
<html>
<head>
<title>JavaScript Example</title>
</head>
<body>
<script type="text/javascript">
var dateObj = new Date('September 26, 89 12:4:25:96');
document.write(dateObj.getMilliseconds());
</script>
</body>
</html>
96
Incase if you haven’t mentioned the milliseconds while creating the date object this function returns 0.
<html>
<head>
<title>JavaScript Example</title>
</head>
<body>
<script type="text/javascript">
var dateObj = new Date('september 26, 89 04:50:12');
document.write(dateObj.getMilliseconds());
</script>
</body>
</html>
0
In the same way if you haven’t passed anything while creating the date object (to the constructor) this function returns the Current milliseconds.
<html>
<head>
<title>JavaScript Example</title>
</head>
<body>
<script type="text/javascript">
var dateObj = new Date();
document.write("Current milliseconds: "+dateObj.getMilliseconds());
</script>
</body>
</html>
Current milliseconds: 504
The range of milliseconds in JavaScript is from 0 to 999 if you use value out of this range this function returns 0.
