Function to get yesterday's date in Javascript in format DD/MM/YYYY

I've been looking for a while to get yesterday's date in format DD/MM/YYYY.
Here's my current code:

var $today = new Date();

var $dd = $today.getDate();

var $mm = $today.getMonth()+1; //January is 0!



var $yyyy = $today.getFullYear();

if($dd<10){$dd='0'+dd} if($mm<10){$mm='0'+$mm} $today = $dd+'/'+$mm+'/'+$yyyy;

With this, I get today's date in format DD/MM/YYYY (thanks SO).
But when I try this:

var $yesterday = $today.getDate()-1;

as recommended on this site somewhere else (lost the link), I get an error saying that getDate() was not found for this object.

I'm using my script with Sahi, but I don't think it's linked, as Sahi has no trouble with Javascript.

Thank you in advance.

The problem here seems to be that you're reassigning $today by assigning a string to it:

$today = $dd+'/'+$mm+'/'+$yyyy;

Strings don't have getDate.

Also, $today.getDate()-1 just gives you the day of the month minus one; it doesn't give you the full date of 'yesterday'. Try this:

$today = new Date();

$yesterday = new Date($today);

$yesterday.setDate($today.getDate() - 1); //setDate also supports negative values, which cause the month to rollover.

Then just apply the formatting code you wrote:

var $dd = $yesterday.getDate();

var $mm = $yesterday.getMonth()+1; //January is 0!



var $yyyy = $yesterday.getFullYear();

if($dd<10){$dd='0'+$dd} if($mm<10){$mm='0'+$mm} $yesterday = $dd+'/'+$mm+'/'+$yyyy;

Because of the last statement, $yesterday is now a String (not a Date) containing the formatted date.
