Source: Questions

This section describes the source code for how you would write the questions in HTML.

Example: <select name="q1" onChange="checkMenu(this.name, this.options[this.selectedIndex].value)">

Your select tags need to include the following attributes:

• name="qX" – where X is the question number
• onChange="checkMenu(this.name, this.options[this.selectedIndex].value)"

Questions must always be numbered sequentially starting from 1. This does not mean that a question can't be seen as 'question 1a' to the user. There is no double-up of question numbers.

The value of each select option is a number. These are numbered sequentially starting from 0 (for the unanswered state) for each question.

Example: <option value="0">--select--</option>
<option value="1">hieroglyphics</option>

There is always one image per question. Images must be named according to their question. For example, name="iq1" – i means image, q1 is the question it's attached to. Images should start as blank.gif with an empty alt. The Javascript will change the image as appropriate.

Example: <img src="/learningplace/images/courses/interactive/blank.gif" width="18" height="18" name="iq1" alt="">

The Reset button must always include the following attributes:

• type="reset"
• name="Reset"
• value="Reset"
• onClick="startAgain(Z)" – where Z is the number of questions/images

Example: <input type="reset" name="Reset" value="Reset" onClick="startAgain(3)">

Below is the source code for the example.

Source: Javascript

It's preferable to link to a separate Javascript file although, for pages individually loaded into Blackboard, including the script within the HTML is acceptable.

There are three parts of the script that need to be modified:

• Pre-loading of response image placeholders
• Setting the question variables
• Setting the response image variable paths

The response image placeholders must always start as blank.gif. Only change the value for the number of images – for (var i=1; i<=numberofimages; i++) {, and adjust the path to blank.gif – eval("iq"+i+".src = \"blank.gif\"");.

Set a new variable for each question as a string. The variables must appear as:

• var vqX = "Y"; – where X is the question number and Y relates to the option number of the correct answer.

Example: var vq1 = "3";

In this example there are four options in each question.

Set the paths of the response image variables as needed. Do not remove or rename these variables.

Below is the source code for the Javascript of the above example.
