Javascript validation - System Date

Guyz,

I have 2 textboxes (PHP script) i need to validate them using Javascript. one textbox is to type date.. but the user should not be able to type a future date and press submit.

i wrote a javascript validation :

<script language="JavaScript">
        <!--
        function CompareDates(str1,str2)
        {
            var dt1  = parseInt(str1.substring(0,2),10);
            var mon1 = parseInt(str1.substring(3,5),10);
            var yr1  = parseInt(str1.substring(6,10),10);
            var dt2  = parseInt(str2.substring(0,2),10);
            var mon2 = parseInt(str2.substring(3,5),10);
            var yr2  = parseInt(str2.substring(6,10),10);
            var date1 = new Date(yr1, mon1, dt1);
            var date2 = new Date(yr2, mon2, dt2);
       
            if(date2 < date1)
            {
                return false;
            }
            else
            {
                return true;
            }
        }
        function validate()
        {
            var str2 = document.getElementById("date").value;
           
            var str1 = "23/10/2010";
           
           
            if (document.frm.date.value=="")
            {
                alert("Please enter date");
                document.frm.date.focus();
                return false;
            }
            else if (document.frm.number.value=="")
            {
                alert("Please enter number");
                document.frm.number.focus();
                return false;
            }           
            else if (eval(document.frm.number.value)<=0)
            {
                alert("Please enter number positive");
                document.frm.number.focus();
                return false;
            }
            else if (CompareDates(str1,str2))
            {
                alert("To date cannot be greater than from date");
                document.frm.date.focus();       
                return false;
            }
            else
                return true;           
        }   
        //-->
        </script>

This works perfectly but the problem is validation takes current date from :

 var str1 = "23/10/2010"; 

Code (markup):

i need that to be the system date so i dont have to change the str value everytime.. any help?

Thanks in advance

 

Just replace:

var str1 = "23/10/2010";

Code (markup):

with:

var date = new Date();
var str1 = date.getDate() + '/' + (date.getMonth() + 1) + '/' + date.getFullYear();
