Date Validation

[balan]

Hello,
I have a text field with a date picker near to it. I want the user to pick a date. Like ( Date Between 12-03-2006 and 04-09-2006 ). If the user chooses 11-03-2006 or 05-09-2006 an alert message should be displayed. Pls help.

Hello,
I am asking the user to choose a date between Jan 01 to Jan 10. The user picks his date using the date picker. If the user chooses a date which is not between the jan1 to jan10 it should display an alert message saying "pls choose the date within the specified range". I am accepting the date format as - DD/MM/YYYY

Thanks

return false;
}

var minDate = new Date("Sat, 1 Jan 2006");
var maxDate = new Date("Wed, 1 Mar 2006");

return false;
}

function isValidDate(inY,inM,inD) {
var testDate = new Date(inY, inM, inD);

return ( testDate.getDate() == inD
&& testDate.getMonth() == inM
&& testDate.getFullYear() == inY) ? testDate : false;
