You can choose to place the script in the head of your document or in an external .js file. Make sure that when inserting the head HTML, your source is the name of your .js file.

One question is an array which consists of 3 or more values. These values are the question, followed by the numerical answer and as many options as you wish. They are to be enclosed with [] brackets. E.g. ['What is my question?', '3', 'A', 'B', 'C', 'D', 'E'] Following in the format of [question, numerical answer, options]. In the example, my numerical answer is 3 because the answer is C and C is the 3rd option - which means A is the first option. Edit under the first variable - quiz...

Your explanation array must correspond to the question array. If your question is the 5th array, your explanation also has to be the fifth array. Edit under explain. It is self-explanatory. If you want to remove the explain function, simply remove the which surrounds .

At the end of the quiz, there will be a message to tell the participant that he/she has completed the quiz. You can edit that message at the endingmessage variable. Self-explanatory too.

You can always add an ajax function to submit the participant's answers and scores. I recommend putting a div(display:none) or hidden input to act as an answer holder. So every time the ans(); is triggered, the answer holder will be updated with new information, of course with additional javascripting. You can place an ajax function inside the }else{ of question(); where the quiz comes to an end.
