Fragetyp – Langer Freitext
From LimeSurvey Manual
Kurzbeschreibung
This question type collects multiple lines of text input.
Basis-Einstellungen
Pflichtangabe
Beschreibung:
Mit dieser Option wird festgelegt, ob eine bestimmte Frage von Umfrageteilnehmern zum Fortfahren beantwortet werden muss. Müssen nur bestimmte Unterfragen beantwortet werden, verwenden Sie das Attribut minimale Antwort in der Registerkarte Logik (nur bei Matrix- oder Mehrfachauswahlfragen).
Wenn Sie eines der vorinstallierten Designvorlagen verwenden und Pflichtangabe aktiviert ist, wird neben der Frage ein rotes Sternchen angezeigt. Wenn Sie dieses ausblenden möchten, schauen Sie bitte in unsere FAQ.
Verfügbare Optionen:
- An – Die Frage muss beantwortet werden, bevor der Teilnehmer zur nächsten Seite gehen kann – die Antwortoption „Keine Antwort“ wird nie angezeigt.
- Weich – Wenn die Frage nicht beantwortet wird, wird eine Warnung angezeigt, wenn versucht wird, zur nächsten Seite zu gelangen – der Teilnehmer kann die Warnung jedoch ignorieren und fortfahren. Beachten Sie, dass die Option „Keine Antwort“ weiterhin angezeigt wird (falls in den Einstellungen der Umfragepräsentation aktiviert)
- Aus (Standard) – Frage kann unbeantwortet bleiben
Validierung (mit regulären Ausdrücken) (preg_validation)
Beschreibung
Mit dieser Option können Sie einen regulären Ausdruck angeben, mit dem Sie alle Teile einer Frage validieren können.
Wenn eine Frage oder ein Unterfragewert die Validierungsanforderungen nicht erfüllt, wird die Hintergrundfarbe des Texteingabefelds in Rot geändert, damit Benutzer leicht erkennen können, welche Teile der Frage korrigiert werden müssen. Somit können Sie eine On-Page-Validierung durchführen. Auf diese Weise müssen Sie nicht darauf warten, dass der Benutzer auf die Schaltfläche „Senden“ klickt, um die entsprechende Frage zu bestätigen.
Gültige Werte
- Jeder gültige reguläre Ausdruck

Bedingung (früher „Relevanzgleichung“)
Beschreibung:
Ist der Ergebniswert der Bedingung „1“ oder „wahr“, ist die Frage im Umfragekontext „relevant“, wird also dem Umfrageteilnehmer angezeigt. Wenn nicht, wird die Frage ausgeblendet. Für jede Umfragefrage können Sie eine Relevanzgleichung angeben. Diese Funktion ist der Nachfolger von conditions und unterstützt eine wesentlich komplexere bedingte Logik.
Syntax-Hervorhebung:
Wenn Sie die Bedingung speichern, wird sie ausgewertet und syntaktisch hervorgehoben. Eventuelle Fehler werden farblich gekennzeichnet, sodass Sie sie schnell erkennen und beheben können.
Gültige Werte:
- Jede Bedingung, die die Syntax ExpressionScript ohne umgebende geschweifte Klammern verwendet.
Beispiel
Hier finden Sie Beispiele für die Syntax-Hervorhebung (derzeit nur auf Englisch).
Erweiterte Einstellungen
Breite Eingabefeld (text_input_width)
Beschreibung
Dieses Attribut legt die Breite der Texteingabefelder fest (des "Wrappers" der Texteingabefelder). Das Eingabefeld wird verwendet, um eine Antwort auf die (Teile-) Frage einzugeben. Wenn der Wert der Breite ausreichend hoch ist, wird das Texteingabefeld in der nächsten Zeile angezeigt. Bitte beachten Sie, dass diese Option nicht die Größe der Eingabe oder die Breite der gesamten Spalte festlegt!
Verfügbare Optionen
- Standard: Wenn diese Option ausgewählt ist, wird diesem Attribut ein Standardwert zugewiesen, sodass sowohl die Beschriftung als auch das entsprechende Texteingabefeld in derselben Zeile stehen. Wenn die Breite des Texteingabefelds beispielsweise 41% beträgt, ist der Wert der Breite des Texteingabefelds ein Wert, der sowohl die Beschriftung als auch das Eingabefeld in derselben Zeile zulässt (in diesem Fall 58%). Wenn die Breite des Texteingabefelds höher als 58% ist, wird das Texteingabefeld in der nächsten Zeile angezeigt
- 8%; 17 %...92% , 100%: Je größer der ausgewählte Wert ist, desto breiter ist das Texteingabefeld.
Beispiel
- Wenn das Eingabeelement unter der Unterfrage / Beschriftung angezeigt werden soll, wählen Sie die Option 100% aus der Dropdown-Liste.
Anzahl Zeilen (display_rows)
Beschreibung
Es legt die Anzahl der angezeigten Zeilen fest, ohne die Bildlaufleiste zur Überprüfung des gesamten Inhalts zu verwenden. Wenn mehr Zeilen vorhanden sind als in diesem Feld angegeben, wird eine Bildlaufleiste angezeigt. Der Standardwert für den Fragetyp „Langer Freitext“ ist 5, während für den Fragetyp „Riesiger Freitext“ 30 beträgt.
Gültige Werte
- Jede positive ganze Zahl größer 0
Beschreibung
Wenn diese Option aktiviert ist, wird die Frage immer ausgeblendet und den Umfrageteilnehmern nicht angezeigt. Diese Funktion kann in folgenden Szenarien verwendet werden:
- Wenn Sie eine Frage mit einer URL vorfüllen möchten und diese nicht auf dem Bildschirm angezeigt werden soll. Dies überschreibt alle in der Umfrage verwendeten Bedingungen, da die jeweilige Frage nicht einmal in die Seite eingebettet wird.
- Wenn Sie einen Wert im laufenden Betrieb über das Expressionscript speichern oder berechnen möchten.
'Hinweis:' Ein häufiger Fragetyp, der mit dieser Funktion verwendet wird, ist der Fragetyp Gleichung. Verfügbare Optionen
- Ein
- Aus (Standard)
Insert page break in printable view (page_break)
Description
This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question.
Available options
- On
- Off (default)
Time limit (time_limit)
Description
Setting the time_limit attribute on a question will cause a countdown timer to begin counting down as soon as that question/page is loaded. At the expiry of the countdown timer the question will either automatically move on to the next page or become read-only.
Valid values
- Any positive integer number
Example
Set it to 240 to count down from 4 minutes (240 seconds).

<onlyinclude>
Time limit action (time_limit_action)
Description
Sets the action performed when a time_limit has expired. By default the action for a time limit is "Warn and move on", which means the system will give a short warning that the time limit has expired before saving the question and effectively automatically clicking "Next >>". The alternative choices are to:
- "Move on without warning", which automatically clicks the "Next >>" button after the timer is finished but without any warning message.
- "Disable only", which disables changes in the question so the participant can't change anything, but doesn't automatically click the "Next >>" button.
This setting is only applicable if the general time limit setting is activated.
Available options
- Warn and move on (default): will warn the participant that the time has expired, and then click the next button
- Move on without warning: will immediately click the next button after the time limit has expired
- Disable only: will disable the answer after the time limit has expired but not automatically click next
Additional information
Attention : If the question is mandatory, or a question in the group is mandatory, a JavaScript loop will be created if the mandatory question(s) is/are not answered. As a result, an error will be displayed on the screen that certain questions have not be filled in, which in turn will trigger the refresh of the page.Instead of relying on mandatory questions, you may use expressions (read more about question and subquestion validation equations) to make the user not leave empty the answer fields. To see how the validation equations work, check the following example.
In the case in which you want to apply a timer to a question group, activate the group-by-group survey mode, set up a question to use the time limit functionality, and choose the warn and move on (default) option as time limit action. Once the question timer expires, the survey will move to the next page.

Time limit disable next (time_limit_disable_next)
Description
It allows disabling the "next" button while a time_limit countdown is occurring. Normally, even if the time limit countdown is active, if the participant wants to click "Next" and move on to the next question or question group, they can simply click on the "Next" button (thus cutting short the time spent on the question or question group). By activating this function, the next button will appear greyed out and will not be available until the countdown timer has finished.
This settings is only applicable if the general time limit setting is activated.
Available options
- On - The "Next" button will be disabled until the time limit countdown is complete.
- Off (default)
Note: If your survey uses the group by group format, this function applies to the whole group this question belongs to.
Time limit disable prev (time_limit_disable_prev)
Description
It allows disabling the "previous" button while a time_limit countdown is occurring. Normally, even if a time limit countdown is active, if the participant wants to click on "Previous" and move to the previous question or question group, they can simply click on the "Previous" button (thus cutting short the time spent on the question or question group). By activating this function, the previous button will appear greyed out and will not be available until the countdown timer has finished.
This settings is only applicable if the general time limit setting is activated.
Available options
- On - the "Previous" button will be disabled until the time limit countdown is complete.
- Off (default)
Note: If your survey uses the group by group format, this function applies to the whole group this question belongs to.
Time limit countdown message (time_limit_countdown_message)
Description
Write in this field the text message you wish to be displayed in the countdown timer during the countdown. This setting is applicable only if the general time limit setting is activated. If nothing is written, the the field will use the default value: "Time remaining".
Time limit timer CSS style (time_limit_timer_style)
Description
It allows (and overrides the default) css styling used to display the countdown timer. The default style value for this attribute will be used if it does not exist, which is: 'width: 150px; margin-left: auto; margin-right: auto; border: 1px solid #111; text-align: center; background-color: #EEE; margin-bottom: 5px; font-size: 8pt;'.
Any text entered into this attribute will overwrite the entire default css style, so you should ensure that care is taken when entering a value for this attribute. A simple way to hide this is to copy the default style into this attribute and add 'display: none;' to the end.
This settings is only applicable if the general time limit setting is activated.
Time limit expiry message display time (time_limit_message_delay)
Description
This attribute sets how many seconds the time_limit_message is displayed before the time_limit_action occurs. If this attribute is not set, it defaults to a value of 1 (1 second).
This settings is only applicable if the general time limit settings is activated.
Example
time_limit_message_delay: 5 = the message displays for 5 seconds
Time limit expiry message (time_limit_message)
Description
This is the text of the message that appears to the participant when the time_limit has expired. By default, this message is "Your time to answer this question has expired". If the time_limit_action attribute is set to "Move on without warning" this message is not displayed. You can set the CSS style for this text in the time_limit_message_style attribute (see below).
This settings is only applicable if the general time limit settings is activated.
Example
time_limit_message: The time limit on answering this question is now up.
Time limit message CSS style (time_limit_message_style)
Description
It allows (and overrides the default) css styling used to display the time limit message. The default style value for this attribute will be used if it does not exist, which is: 'top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: white; z-index: 1002; text-align: center; overflow: auto'.
Any text entered into this attribute will overwrite the entire default css style, so you should ensure that care is taken when entering a value for this attribute. It is strongly recommended that you re-use the z-index value, or that, at least, the z-index value is higher than that used for the time_limit_warning_message_style attribute (which defaults to 1001).
Example
Set to: top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: black; color: white; z-index: 1010; text-align: center; overflow: auto
Time limit warning message timer (time_limit_warning)
Description
With the help of this attribute, you can set the time (in seconds) when the time_limit_warning_message will be displayed before the time limit expires. Setting a value for this attribute activates the time limit warning message.
This settings is only applicable if the general time limit settings is activated. This setting also exists for a second warning message.
Example
If you set this to '20', then the time limit warning message will appear 20 seconds before the time limit countdown reaches zero.
Time limit warning message display time (time_limit_warning_display_time)
Description
It sets for how long the time_limit_warning_message is displayed before it is removed/hidden from the screen. By default, if the time_limit_warning_message appears, it will remain visible until the countdown timer has completed the countdown. If a value greater than zero is introduced in this field, the message will be hidden after that many seconds.
This setting is applicable only if the general time limit setting is activated. This setting also exists for a second warning message.
Example
time_limit_warning_display_time: 10 = The time limit warning message will disappear 10 seconds after its moment of appearance.
Time limit warning message (time_limit_warning_message)
Description
If set up, it displays the text of the warning message which is displayed for a fixed period of time before a time limit expires. The default text is "Your time to answer this question has nearly expired. You have {TIME} remaining." {TIME} is replaced by a formatted description which represents the amount of time left (i.e. "30 seconds", "1 minute or 5 seconds"). This message only appears if the time_limit_warning attribute exists. You can set from the time_limit_warning attribute when the message (time_limit_warning_message) appears.
This question attribute is only applicable if the time limit setting is activated and you set some text in the time limit warning message field. This setting also exists for a second warning message.
Example
Attention: In {TIME} the time limit to answer question will expire.
Time limit warning CSS style (time_limit_warning_style)
Description
It allows (and overrides the default) css styling used to display the time limit warning message. The default style value for this attribute will be used if it does not exist, which is: 'top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: white; z-index: 1001; text-align: center; overflow: auto'.
Any text entered into this attribute will overwrite the entire default css style for the warning message, so you should ensure that care is taken when entering a value for this attribute. It is strongly recommended that you re-use the z-index value, or that, at least, the z-index value be lower than that used for the time_limit_message_style attribute (which defaults to 1002).
This settings is only applicable if the general time limit setting is activated. This setting also exists for a second warning message.
Example
top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: gray; color: white; z-index: 1001; text-align: center; overflow: auto
Question validation equation (em_validation_q)
Description
This is an equation that is used to validate the entire question (e.g, all of its parts collectively for a multi-answer question). If the question fails the validation criteria, then em_validation_q_tip message will be displayed (it uses the CSS style .error). This tip uses the .em_q_fn_validation CSS style, which is hidden by default within template.css.
The main difference between this feature and the subquestion validation equations (em_validation_sq option) is that for this feature, if the question (or question parts) fail validation, then an error message could be shown. For the subquestion validation, each text entry cell (e.g., in an array question type, but it can also be applied to single entry question types) will be styled so that the background color is (light) red.
Valid values
- Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.
Example
- You want to collect demographic information from users via a multiple short text question, and you want to validate that the user has entered a valid email address and phone number.
This example shows how the question looks with invalid answers:
And here is what it looks like with one invalid answer:
Here is how you edit a question to enter that information:
And here is part of the Show Logic File output that lets you check the accuracy of your expression and ensure that there are no syntax errors:
As you can see, the validation equation tests that both the email and phone number are either empty or match a regular expression filter.
The validation tip only shows the warning message if the phone or email appears invalid.
If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file: Em_validation_q_example.zip.
Tip for whole question validation equation (em_validation_q_tip)
Description
If you are using the question validation equation, you can use this box in order to display an optional message as question tip on how the question has to be filled out.
Valid values
- Any string or equation that makes use of the ExpressionScript syntax.
Example
See the example from the question validation equation wiki section- it shows how the tip can be tailored to show which parts of a multiple short text question fail the validation criteria.
Sub-question validation equation (em_validation_sq)
Description
This is an equation that is used to validate each subquestion (text field) individually. Any text field that does not pass these validation conditions will have its background color turned pink (using the .em_sq_fn_validation CSS style) to highlight the error. Note that this is available in addition to the regular expression-based validation option.
Valid values
Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.
Examples
For example, if you want to allow only numbers that are a multiple of 3 as answers, the equation would be:
(this / 3) == floor(this/3)
The reserved variable this is automatically replaced by a reference to the active text entry cell.
Tip for sub-question validation equation (em_validation_sq_tip)
Description
If you are using em_validation_sq, this is an optional message/tip that will be displayed if the introduced answer is incorrect.
Valid values
- Any string
Example
- Continuing the example of validating emails, the tip might be "Please enter valid email addresses."
