The alert is showing every change event, but the if condition is not working. How to fix it?

Here is my code.

$("input").change(function() {
  var date = document.getElementById('<%= txtRegisteredDate.ClientID%>').value;
  var todaydates = new Date().format('dd/MM/yyyy');

  if (date > todaydates) {
    alert('date is greater than today date');
  }
})

    There is no `format` function in Date – Jack jdeoel Jul 03 '18 at 10:16

    Even if `.format` worked. Why are you comparing _strings_ in a `dd/MM/yyyy` format? If you wanted to compare strings, you’d use `yyyy-mm-dd`. But you can just compare `Date` objects directly: `new Date() < someOtherDate`. – Sebastian Simon Jul 03 '18 at 10:19

Try converting your date variables to an object before the comparison.

e.g:

var date = document.getElementById('<%= txtRegisteredDate.ClientID%>').value;
var todaydates = new Date();

if((new Date(date) > todaydates))
{
   alert('date is greater than today date');
}
