Les options (paramètres généraux)
Obligatoire
Description
Cette option permet aux administrateurs de l'enquête de demander à leurs répondants de répondre à certaines questions de l'enquête. Si les questions obligatoires ne reçoivent pas de réponse, les répondants ne pourront pas poursuivre. Si vous avez une question comportant plusieurs sous-questions et que vous souhaitez répondre à certaines sous-questions seulement, utilisez l'attribut minimum Answer situé sous l'onglet Logique.
Options disponibles
- Activé - Il faut répondre à la question avant que le participant puisse passer à la page suivante - l'option de réponse « Pas de réponse » n'est jamais affichée.
- Soft - Si la question n'obtient pas de réponse, un avertissement s'affiche lorsque vous essayez de passer à la question. la page suivante - cependant, le participant peut choisir d'ignorer l'avertissement et de continuer. Notez que l'option « Pas de réponse » est toujours affichée (si elle est activée dans les paramètres de présentation de l'enquête)
- Désactivé (par défaut) - La question peut rester sans réponse
Condition (anciennement "Équation de pertinence")
Description
Si la valeur du résultat de la condition est « 1 » ou « vrai », la question est « pertinente » dans le contexte de l'enquête, c'est-à-dire qu'elle est présentée au participant à l'enquête. Sinon, la question est cachée. Toute question d'enquête vous permet de spécifier une équation de pertinence. Cette fonction est le successeur de conditions et prend en charge une logique conditionnelle beaucoup plus complexe.
Coloration syntaxique
Chaque fois que vous enregistrez la condition, elle est évaluée et mise en évidence par la syntaxe. Toutes les erreurs seront codées par couleur afin que vous puissiez les détecter et les corriger rapidement.
Valeurs valides
- Toute condition utilisant la syntaxe ExpressionScript, sans accolades.
Exemples
Voici de bons exemples de syntaxe highlighting.
Paramètres avancés
Largeur de réponse (answer_width)
Description
Cette valeur définit la largeur de la colonne de réponse en utilisant un système de pourcentage. Par exemple, si vous saisissez 40 dans ce champ, 40 % de la largeur de la question sera utilisée pour les réponses. La largeur restante sera répartie également entre les sous-questions.
Valeurs valides
- Toute valeur entière comprise entre 1 et 100.
Ordre aléatoire
Randomization group name (random_group)
Description
It places the questions into a specified randomization group, all questions included in the specified group being displayed in a random order to the survey respondents.
You can find a sample survey using randomization group name in ExpressionScript sample survey.
Valid values
Just enter any string you like (for example: 'group1'). All question which have set the same string within the randomization group name box will have their place in the survey randomized (=randomly exchanged among each other).
Preview
To preview the questions use the preview survey instead of the preview question group function, as the second has been reported to not show the questions in a randomized order.
Header for first scale (dualscale_headerA)
Description
This is the text to be displayed above the first scale of answer options.
Valid values
- Any text string
Header for second scale (dualscale_headerB)
Description
This is the text to be displayed above the second scale of answer options.
Valid values
- Any text string
Use dropdown boxes (use_dropdown)
Description
If this function is enabled, the answer options layout will use dropdown boxes instead of radio buttons.
Available options
- On - dropdown boxes are used.
- Off (default) - radio buttons are used.
Dropdown separator (dropdown_separators)
Description
In the dual scale questions with the dropdown option enabled, if this attribute is set, the layout will use the provided text as a separator between the dropdown boxes that correspond to each scale.
Valid values
- Any text string.
Example
Dropdown prefix/suffix (dropdown_prepostfix)
Description
In the dual scale questions with the dropdown option enabled, if this attribute is set, the layout will use the provided text as a prefix and/or suffix before and after the dropdown input elements. The format is prefix|suffix.
Valid values
- Any text string.
Examples
- Suffix with the letters EUR: "|EUR"
- Prefix with the letters USD: "USD|"
- Both prefix and suffix: "USD|EUR"
Screenshot prefix:
Array filter (array_filter)
Description
The Array filter setting allows you to use any multiple choice question to select or set which responses are displayed in a subsequent list, array or multiple choice question.
- Multiple choice
- Multiple choice with comments
- Multiple short text
- Multiple numeric
- Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, Column)
- Array (Dual Scale, Text, Numbers)
- Ranking
Furthermore, each of these question types can be filtered.
The only exception is Array (Column), which can filter other questions, but not itself.How to set a filter
To set a filter, enter the question code of a multiple options question in the array filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array Filter' box to start the filtering process of the answers. Only the answer options that are selected in question Q1 will be visible in the array_filter-ed question.
Cascading
The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.
Array filter example
Let's take a look at the following example to better understand the power of this setting:
In the screenshot from above, we got two questions. The first one is a multiple short text question type, while the second one is an array dual scale question type. The answers you provide in the first question will be listed in the second one. Technically, the answers you provide to the subquestions from the first question are filtered and displayed in the second question.
This example can be downloaded from the following link: limesurvey_group_32.lsg. Import this question group into your LimeSurvey installation.
Array exclusion filter (array_filter_exclude)
Description
The Array filter exclusion setting allows you to use any multiple choice question to select or set which responses are NOT displayed in a subsequent list, array or multiple choice question.
- Multiple choice
- Multiple choice with comments
- Multiple short text
- Multiple numeric
- Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, By column)
- Array (Dual Scale, Text, Numbers)
- Ranking
Furthermore, each of these types of questions can filtered.
The only exception is Array by column which can filter other questions, but it cannot be filtered.How to set it up
Enter the question code of a multiple options question in the array exclusion filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the non-selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array exclusion filter' box to start the filtering process of the answers. Only the answer options that are NOT selected in question Q1 will be visible in your question.
Cascading
The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.
Example
Let's see together the below example:
In the screenshot from above, we got two questions. The first one is a multiple choice question type, while the second one is a multiple choice with comments question type. The answers you provide in the first question will be excluded from the second one. For example, if you select the ComfortUpdate option (that has the subquestion code 'SQ1') and the Plugin option ('SQ4'), the 'SQ1' and the 'SQ4' subquestion correspondents from the second question will be excluded. In our screenshot, we can observe that only the unselected options in the first question and displayed in the second one.

- Any equation, using ExpressionScript syntax, without surrounding curly braces.
Example
If set to X (a random number), the users can submit the survey form if they select at least X checkboxes. If this option is utilised for ranking questions, this ensures that at least three items are ranked before allowing the respondent to submit the answers/survey.
