  • In this format we include a superscript to the date value. 
  • The idea is to identify the date and then select a superscript based on the date value.
  • The sup() method is used to display a string as superscript text.

Syntax :

var sup = "  " ;

Sample Code :

<html>
<head>
    <title> Formatting-date </title>
</head>
<body>
    <script type="text/javascript">
        var m_names = new Array("January", "February", "March", 
            "April", "May", "June", "July", "August", "September", 
            "October", "November", "December");	
        var d = new Date();
        var curr_date = d.getDate();
        var sup = "";
        if (curr_date == 1 || curr_date == 21 || curr_date ==31)
        {
            sup = "st";
        }
        else if (curr_date == 2 || curr_date == 22)
        {
            sup = "nd";
        }
        else if (curr_date == 3 || curr_date == 23)
        {
            sup = "rd";
        }
        else
        {
            sup = "th";
        }
        var curr_month = d.getMonth();
        var curr_year = d.getFullYear();
        document.write(curr_date + "<SUP>" + sup + "</SUP> " + 
            m_names[curr_month] + " " + curr_year);
    </script>      
</body>
</html>  

Code Explanation :

   Here <script type="text/javascript"> specifies the type attribute of the Internet media type (formerly known as MIME type) of a script. "text/javascript” specifies the media type.

    Here the var m_names = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September",  "October", "November", "December"); specifies the getMonth() function that gives us the month in a non-numeric form. To convert this value into the month name, we will employ an array. The array would contain all the 12 month names.

    var d = new Date () specifies a variable d contains a new date object. We can now call the various methods of this date object.

    var curr_date = d.getDate() it return the current day of the month.

    var sup = "" specifies to Returns the sup() method is used to display a string as superscript text.

    We first initialize the variable sup that would store the superscript value. Using if (curr_date == 1 || curr_date == 21 || curr_date ==31), we check the value of the current date and according to that we  assign the  value to sup(super script). (if condition is false it goes to else if condition).

    sup = "st"; specifies “st” which is used with numbers ending in 1 such as 1st , 21st, 31st pronounced First, Twenty-first, Thirty-first).

    We first initialize a variable sup that would store the superscript value. Using else if (curr_date == 2 || curr_date == 22) we check the value of the current date and accordingly we assign the value to sup(super script). (if condition is false it goes to else if condition).

    sup = "nd"; specifies “nd” which is used with numbers ending in 2 like 2nd, 22nd pronounced second, twenty-second)

    We first initialize a variable sup that would store the superscript value. Using else if (curr_date == 3 || curr_date == 23) we check the value of the current date and accordingly we assign the value to sup(super script). (if condition is false it goes to else condition).

    sup = "rd"; specifies “rd” which is used with numbers ending in 3 e.g. 3rd ,23rd pronounced third , Twenty-third).

    sup = "th"; specifies as an exception to the above rules, all the "teen" numbers ending with 11th , 12th .

    var curr_month = d.getMonth() specifies the current month.

    var curr_year = d.getFullYear() specifies the method that returns the year (four digits for dates between year 1000 and 9999) of the specified date.

  document.write specifies the write() method writes JavaScript code to a document.(curr_date+"<SUP>"+sup+"</SUP>"+ m_names [curr_month] + " " + curr_year); it returns the current date with superscript text month name year (like: 30th May 2016) in this format.

    </script> defines the end of script tag in the sample code.

Sample Output :


    Here in this output we display 30th May 2016 which specifies the datesup (date superscript text) month year.
