Question

I have written a function using javascript for validating a Date selected from a calendar to a text box, with the current date. And I not getting a correct result. The date format displayed in text box is “01-Oct-2010”. And the function i had created is as follows :

function CheckDate() {
    var today = new Date();
    var startDate = document.getElementById("<%=txtStartDate.ClientID %>").value;
    var endDate = document.getElementById("<%=txtEndDate.ClientID %>").value;

    if (Date.parse(endDate) >= today) {
        alert("End Date should not be greater than Today");
    }

    return true;
}

Answer 1

var myDt=new Date(); 
myDOB = document.getElementById('dateField').value.split('-');
myDate = myDOB[0];
myMonth= getMonthInDigit(myDOB[1]);
myYear = myDOB[2];
var now = new Date();
myDt.setFullYear(myYear,myMonth,myDate); //here year, month, date value should be parsed from the value u get
var diff = (now.getTime() - myDt.getTime()) 
if(diff < 0){ 
  alert("End Date should not be greater than Today"); 
}

you can use the above javascript code.

Note: Make getMonthInDigit function which return value in digit as required.
