From Date & To Date Validation in javascript

[kirankumarn]

I want to validate for From Date & To Date (ie., From Date should not be greater than To Date & also From Date & To Date should not be greater than current date) & Dates are in us format

Show your code. An easy way to compare is to get two Date objects and compare them:

if (fromDate > toDate) {
    alert("Error! ...");
    // whatever you want to do here
}

So get your date inputs into a Date object - see this link for more details.

Thanks for the suggestion acoder it really helped me a lot

No problem. Perhaps you could post your working code for the benefit of others.

This is the code which i developed & the date will be in us date

var objFromDate = document.getElementById("fromdate").value;
var objToDate = document.getElementById("todate").value;

var date1 = new Date(objFromDate);
var date2 = new Date(objToDate);

var date3 = new Date();
var date4 = date3.getMonth() + "/" + date3.getDay() + "/" + date3.getYear();
var currentDate = new Date(date4);
	
	if(date1 > date2)
	{
	    alert("fromdate should be less than todate");
		return false; 
	}
	else if(date1 > currentDate)
	{
	    alert("From Date should be less than current date");
		return false; 
	}
               else if(date2 > currentDate) 
               {
                   alert("To Date should be less than current date");
		return false; 
                }

How can i edit the above code b'coz there is a little issue in current date. I want to add the new code which works perfectly for my requirement

[kirankumarn]

This is the code for date comparison

var objFromDate = document.getElementById("fromdate").value; 
var objToDate = document.getElementById("todate").value;

var FromDate = new Date(objFromDate);
	var ToDate = new Date(objToDate);
	var valCurDate = new Date();
	valCurDate = valCurDate.getMonth()+1 + "/" + valCurDate.getDate() + "/" + valCurDate.getYear();
	var CurDate = new Date(valCurDate);
	
	if(FromDate > ToDate)
	{
	    alert(fromname + " should be less than " + toname);
		return false; 
	}
	else if(FromDate > CurDate)
	{
	    alert("From date should be less than current date");
		return false; 
	}
	else if(ToDate > CurDate)
	{
	    alert("To date should be less than current date");
		return false;
	}

Two things I should point out:
1. There's no need to create two objects for the current date. When you create a new Date object, it's automatically set to today's date:

var today = new Date();

2. You should validate the actual string for the "from" and "to" dates that they are valid dates, e.g. with regular expressions.

PS. please use code tags around your code: [code]like this[/code] It makes it a lot easier to read.

Thanks acoder for your feedback

you can check this using the following jquery code

 var EnteredDate = document.getElementById("txtdate").value; //for javascript

            var EnteredDate = $("#txtdate").val(); // For JQuery

            var date = EnteredDate.substring(0, 2);
            var month = EnteredDate.substring(3, 5);
            var year = EnteredDate.substring(6, 10);

            var myDate = new Date(year, month - 1, date);

            var today = new Date();

            if (myDate > today) {
                alert("Entered date is greater than today's date ");
            }
            else {
                alert("Entered date is less than today's date ");
            }
        }
