JQuery Check Given Date Greater than Current Date or Today Date JavaScript

Aug 27, 2013
Introduction

Here I will explain how to use jQuery to check given date greater than current date or today date in JavaScript or check date greater than current date using JavaScript / jQuery.


To implement this we need to write the code like as shown below


<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>jQuery Check Given Date Time Greater than Current Date time in JavaScript</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script type="text/javascript">
$(function() {
$('#btnConvert').click(function() {
var param1 = new Date();
var ddate = $('#txtdate').val();
var time = $('#txttime').val();
var hours = Number(time.match(/^(\d+)/)[1]);
var minutes = Number(time.match(/:(\d+)/)[1]);
var format = time.match(/\s(.*)$/)[1];
if (format == "PM" && hours < 12) hours = hours + 12;
if (format == "AM" && hours == 12) hours = hours - 12;
var sHours = hours.toString();
var sMinutes = minutes.toString();
if (hours < 10) sHours = "0" + sHours;
if (minutes < 10) sMinutes = "0" + sMinutes;
ddate = ddate + " " + sHours + ":" + sMinutes + ":00";
var date1 = new Date(ddate);
var date2 = new Date();
if (date1 < date2) {
alert('Please Enter Date time Greater than Current Date time');
$('#txtdate').focus();
return false;
}
})
})
</script>
</head>
<body>
<table>
<tr>
<td><b>Enter Date:</b></td>
<td><input type="text" id="txtdate" value="08/27/2013" /></td>
</tr>
<tr>
<td><b>Enter Time:</b></td>
<td><input type="text" id="txttime" value="10:00 PM" /></td>
</tr>
<tr>
<td></td>
<td><input type="button" id="btnConvert" value="Convert to AM/PM" /></td>
</tr>
</table>
</body>
</html>
