Validate if date is before date of current date

Using this function, I'm getting a 7 days difference; how can I test whether a date is before the current date?

function validateDate() {
    pickedDate = Date.parse("05-Jul-2012".replace(/-/g, " "));
    todaysDate = new Date();
    todaysDate.setHours(0, 0, 0, 0);
    dateDifference = Math.abs(Number(todaysDate) - pickedDate);
    //7 Days=604800000ms
    if (dateDifference > 604800000) {
        return false;
    } else {
        return true;
    }
}
Solution

  • You can directly compare both dates as

    return pickedDate <= todaysDate

    For exact date comparison considering milliseconds you can use getTime() method

    You can parse date as you have done:

    pickedDatestr = "09-Apr-2010"
var pickedDate = new Date(Date.parse(pickedDatestr.replace(/-/g, " ")))
