Introduction: In this article you will learn how to convert time to 24 hour time format using JQuery as shown in demo below:
Implementation:
 In the default page (.aspx) write the
following code having jQuery function “ConvertTimeFormat” that converts the
time format.
<%@ Page
Language="C#"
AutoEventWireup="true"

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
        function
ConvertTimeFormat() {           
            var
time = document.getElementById('txtTime').value;
            var
hrs = Number(time.match(/^(\d+)/)[1]);
            var
mnts = Number(time.match(/:(\d+)/)[1]);
            var
format = time.match(/\s(.*)$/)[1];
            if
(format == "PM" && hrs <
12) hrs = hrs + 12;
            if
(format == "AM" && hrs ==
12) hrs = hrs - 12;
            var
hours = hrs.toString();
            var
minutes = mnts.toString();
            if
(hrs < 10) hours = "0" + hours;
            if
(mnts < 10) minutes = "0" +
minutes;
            alert("Converted
Time: " + hours + ":" +
minutes);              
        }
</script>
