Source: Questions

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

Example: <input type="radio" name="q1" value="1" id="q0101" onClick="checkRadio(this.name, this.value)">

Your input tags need to include the following attributes:

• type="radio"
• name="qX" – where X is the question number
• value="Y" – where Y is the option number
• id="qXY" – where X is the question number and Y is the option number (double digits for numbers <10)
• onClick="checkRadio(this.name, this.value)"

Questions must always be numbered sequentially starting from 1 and should avoid numbering such as q1a, q1b, etc. unless you are prepared to make major adjustments to the Javascript yourself. This does not mean that a question can't be seen as 'question 1a' to the user.

The number of options depends on the type of question. In the example above there are two options per question. Option 1 is True and option 2 is False. Options must always be numbered sequentially starting from 1 for each question.

The option label should be attached to its input via the label tag. The label tag includes the attribute for="qXY" – the same value as the id of the input.

Example: <input type="radio" name="q1" value="1" id="q0101" onClick="checkRadio(this.name, this.value)"> <label for="q0101">True</label>

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(5)">

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.

With 'true or false' there are only ever two options.

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.
