Configuration

Set up the HTML

Boxes with questions and answers is created by using the following format:

This is a short version of the code used in the demo. You have one
<div id="questionDiv">
ss parent element of all your questions. In there you put two <DIV> tags for each question.

The first one is for the question, the second is the empty box where answers could be dragged. Create as many pairs as you have questions

<div id="answerDiv"> is used as parent element for all your answers. Create one div for each of your answers inside of this div tag.

Note that the id of the answers should match the id of the question, i.e. the numeric part. Example: The <DIV> with id "a1" is the answer to the question with id "q1". You don't have to use "q" and "a" as prefix. The important part is that you have matching numbers.

Layout

Layout is controlled by use of CSS. Look at the comments there for help

Javascript variables

You have two Javascript variables available:

var shuffleQuestions = true; /* Shuffle questions ? */
var shuffleAnswers = true; /* Shuffle answers ? */
var lockedAfterDrag = false;

shuffleQuestions = Shuffle questions
shuffleAnswers = Shuffle answers
lockedAfterDrag = Lock box after it has been dragged. This means that the user will not be able to drag an answer after it has been dropped on an answer.

Javascript function

I have added an empty function to the script:

function quizIsFinished()
{

}

This function is called when everything is solved correctly. You can customize this function as you want. example: put in
alert('Finished! you did it');

Strict or loose doctype

This script works best in Internet Explorer if you use a valid doctype. You can choose between using the loose or strict doctype:

Strict doctype:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

Loose doctype:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Insert this code at the top of your HTML file.
