JavaScript : Creating a Random Quiz

Fundamentals

The aim of this quiz is to have your visitors guess the name of a computer which is only partly shown in a photograph. Our example only uses three questions, so it wouldn't take a visitor long to check out the right answers. But this will suffice for our purpose at this stage.

It's a good idea to start off with a base of fifteen questions. We will keep the smart Alecs on their toes by pulling out three questions at random for each visit.

To set up this random draw, we will use the JavaScript function math.random(). It returns a floating number between 0 and 1. We can combine it with a multiplication and the function math.round() to obtain a procedure which can produce any integer number at random within a specific limit.
