Question

How can I deduce a day for a date object in JavaScript?

Example:

If I assig a date into an object as below:

var date_value = this.cfg.getProperty(cfgPageDate); 

and the date format in date_value as below:

Fri May 29 2009 00:00:00 GMT+1000 (AUS Eastern Standard Time) 

how can I deduce a day from this object so that the object date will become as below:

Thu May 28 2009 00:00:00 GMT+1000 (AUS Eastern Standard Time) 

Answer 1

var dat = new Date('2009/05/29'); alert (dat.setDate(dat.getDate()-1));
