Create date based on +### string 1

[southbeach]

I need a script where I can create a date based on a given string. The string is expected to be something like

+###

Where the + sign tells the script to add and ### is the number of days from today.

So, if user typed +2 on a field, onBur will call the JS script/function passing this.value. The JS script should check for + to be 1st character - If there, the field should be populated with the date after adding ### days to current date.

So, +2 should result on 04/10/08 since today's date is 04/08/08.

I can write this in PHP but I do not know enough JS - Hope you guys can help me here.

Thanks!

This should work for adding the days:

function addDays(oldDate, days){
  return new Date((oldDate-0)+(days-0)*1000*60*60*24)
}

For parsing the string, read up on the String object. I suggest

consider this:

var d=new Date();
d.setDate(d.getDate()+30)
alert(d)

Where instead of "30" you could have the number parsed from your string:

var strIn = "+021"
alert(parseInt(strIn,10))
