Randomize answer options/sub questions

In order to synchronize randomization of sub questions/answer options among several questions

As a questionnaire creator

I want to control the randomization with a random seed, which means that the system will generate a unique order based on one value of random seed

Randomize answer options

Example

I have a single question with drinks as answer options.

I want to show the answer options in random order (except None of the above option)

Solution

Use any random seed and a randomization range from 0 to 5

Code

Add a Single question to Questionnaire editor
Go to menu Properties -> Question scripts -> Java script and input below script

quest.randomizeAnswerOptions(3, 0, 5);

Note: quest.randomizeAnswerOptions(randomSeed, startIndex, endIndex): randomize answer options in a range specified by startIndex and endIndex, the order is unique for each randomSeed

Randomize sub questions

Example

I have a single grid question with drinks as sub questions.

I want to show the sub questions in random order

Solution

Use any random seed and a randomization range from 0 to 5

Code

Add a Single question to Questionnaire editor
Go to menu Properties -> Question scripts -> Java script and input below script

quest.randomizeSubQuestions(3, 0, 5);

Note: quest.randomizeSubQuestions(randomSeed, startIndex, endIndex):randomize sub questions in a range specified by startIndex and endIndex, the order is unique for each randomSeed
