Short description
This question types asks the survey participant to enter a single number.
Core settings
Mandatory
Description
This option allows the survey administrators to request their respondents to answer certain survey questions. If the mandatory questions are not answered, the respondents will not be able to proceed further. If you have a question with multiple subquestions, and you require only certain subquestions to be answered, use the minimum answer attribute located under the Logic tab.
Available options
- On - Question must be answered before the participant can proceed to the next page - the answer option 'No answer' is never shown.
- Soft - If the question is not answered, a warning is shown when trying to proceed to the next page - however, the participant can choose to ignore the warning and proceed. Note that the 'No answer' option is still shown (if activated in survey presentation settings)
- Off (default) - Question can be left unanswered
Validation (using regular expressions) (preg_validation)
Description
This option lets you specify a regular expression with which you can validate all the parts of a question.
If any question or subquestion value does not meet the validation requirements, the background colour of the text entry field will be changed to red so that users can easily see which parts of the question need to be corrected. Thus, you can do on-page validation. In this way you will not need to wait for the user to click on the submit button to validate the respective question.
Valid values
- Any valid regular expression
Example
- Click here to check multiple examples.
These Core Settings are available in Version 1.92 and beyond
Condition (previously "Relevance equation")
Description
If the result value of the condition is "1" or "true", the question is "relevant" in the survey context, i.e. it is shown to the survey participant. If not, the question is hidden. Any survey question allows you to specify a relevance equation. This function is the successor of conditions and supports much more complex conditional logic.
Syntax Highlighting
Whenever you save the condition, it is evaluated and syntax-highlighted. Any errors will be color coded so that you can quickly detect and fix them.
Valid values
- Any condition that makes use of the ExpressionScript syntax, without surrounding curly braces.
Examples
Here are good examples of syntax highlighting.
Advanced settings
Please note that the attributes 'Minimum value' and 'Maximum value' are only available from v1.91 or newer.
Prefix (prefix)
Description
A text value to be shown as prefix before the text input box(es). The prefix is shown just left of the input.
If the screen is small, then the prefix will be displayed above the input. If you want to leave it on the left (New in 3.0.0 ) : add suffix-prefix-force class to the question.
Valid values
- Any character or set of characters you wish to be displayed before the input
Example
Entering a value of "$" for this attribute would result in a dollar sign being displayed immediately preceding the text input box.
Suffix (suffix)
Description
A text value to be suffixed to a text entry box. The sufix is shown just right of the input.
On little screen : sufix is shown below the input. If you want to leave it at right (New in 3.0.0 ) : add suffix-prefix-force class to the question.
Valid values
- Any character or set of characters you wish to be displayed after the input
Example
Entering a value of "%" for this attribute would result in a percentage sign being displayed immediately after the text input box.
Hide tip (hide_tip)
Description
Most questions will usually include a tip that says "Please choose one of the following options" or a hint text on how to fill out the question. This attribute allows you to turn off or on this tips/hints.
These tips/hints include validation criteria messages (such as min/max number of answers, min/max/equals sum value). If hide_tip is enabled, these messages will be hidden. However, if the user enters invalid data, the tips will appear. They will be coloured in red, getting changed to green once the validation criteria are met.
Available options
- On - the tips/hints are hidden;
- Off (default).
