You should consider extending prototype rather than doing this procedurally.
Date.prototype.getYesterday = function(){
return new Date(this.getTime() - (24 * 60 * 60 * 1000));
}
var d = new Date();
document.write(d.getYesterday())

I simplified things a little bit. I also made the "yesterday" relative to the date object. That way, you can have the "yesterday" of any date and not just the yesterday of today.
Date.prototype.getYesterday = function(){
return d.setDate(d.getDate()-1);
}
var d = new Date();
document.write(d.getYesterday())

Hey Dan, glad you picked up the getDate trick... but it seems like you meant "this" rather than "d".
Date.prototype.getYesterday = function(){
return this.setDate(this.getDate()-1);
}
var d = new Date();
document.write(d.getYesterday())

I would even extend it a bit further, although it may be overkill for your application.
Date.prototype.addDays = function(daysToAdd){
return this.setDate(this.getDate() + daysToAdd);
}
Date.prototype.getYesterday = function(){
return this.addDays(-1);
}
var d = new Date();
document.write(d.getYesterday())

Those are great solutions that allow for re-use. Often in javascript a simple one-line throwaway is sufficient.
document.write( (new Date()).getDate()-1 ); //Yesterday

Display yesterday's date. Initially, what would happen on the first of every month, the day was displayed as "0" which was not acceptable. This is what I came up with, but I'm not sure if there is a better way to do this in JavaScript.
