how to create a unique id in javascript [ANSWERED]

A recent challenge arose where a client wanted to put a unique order id on their client signup form.

This was to be in javascript and based on both time and a random number. This allowed for a sortable (time based) component followed by a random component.

This is just in case 2 people connect at the same millisecond (unlikely in this case as they have only 500 visitors a day and all would have to login within the same second to get a 50/50 chance of hitting the page at the same time). Comments below if you agree.


Anyway I used stack exchange as my source on this - link below.

Here's the code which was used to put an order id via quantcast
