How do I set/initialize a DateField to today's date -7 days?

I have a couple of places where I need to set a DateField to Today - 7 days, and another to Today - 30 days. Further, the user should not be able to select or input a date greater than the current date.

This should be simple, but the books I'm referencing make it seem convoluted...

Thanks in advance.

use date.getTime() this returns a number which is the number of milliseconds since Jan 1st 1970.

Take that number and subtract/add the number of milliseconds you need.

Then use date.setTime(newNumber) with the new number to set the date value.

See example below:

public function addDays(yourDate:Date, value:Number):void // value parameter is the number of days you want to add, use a negative number to subtract days.
 
{
        // get the number of milliseconds since Jan1st 1970
        var numMS:Number = yourDate.getTime();
 
        // multiply value to get equivalent number of milliseconds
        var spanMS:Number = value * 24 * 60 * 60 * 1000; // days * hours * mins * secs * 1000
 
        // add spanMS to numMS to get number of milliseconds since Jan1st 1970
        // if you've used a negative number this will subtract
        var newMS:Number = numMS + spanMS;
 
        // now set yourDate to the new millisecond value
        yourDate = yourDate.setTime(newMS);
 
}

Thank you - I will be back on this soon. I wasn't aware that, in terms of the Object parameter for selectableRange(), that you could supply only one (min or max).
