Question type - Numerical input/sl

Kratek opis

Ta tip vprašanja od anketiranca zahteva vnos števila.

Glavne nastavitve

Obvezno

Opis

Ta možnost skrbnikom ankete omogoča, da od svojih anketirancev zahtevajo, da odgovorijo na določena anketna vprašanja. Če na obvezna vprašanja ne odgovorijo, anketiranci ne bodo mogli nadaljevati. Če imate vprašanje z več podvprašanji in zahtevate odgovor le na določena podvprašanja, uporabite atribut minimalni odgovor, ki se nahaja pod zavihkom Logika.

Razpoložljive možnosti

• Vklopljeno - na vprašanje je treba odgovoriti, preden lahko udeleženec nadaljuje na naslednjo stran - možnost odgovora 'Brez odgovora' ni nikoli prikazana.
• Soft - Če na vprašanje ni odgovorjeno, se ob poskusu nadaljevanja prikaže opozorilo naslednja stran - vendar se lahko udeleženec odloči, da opozorilo prezre in nadaljuje. Upoštevajte, da je možnost 'Brez odgovora' še vedno prikazana (če je aktivirana v nastavitvah predstavitve ankete)
• Izklopljeno (privzeto) - Vprašanje lahko ostane brez odgovora

Preverjanje (z uporabo regularnih izrazov) (preg_validation)

Opis

Ta možnost vam omogoča, da določite regularni izraz, s katerim lahko potrdite vse dele vprašanja.

Če vrednost katerega koli vprašanja ali podvprašanja ne izpolnjuje zahtev za preverjanje veljavnosti, bo barva ozadja polja za vnos besedila spremenjena v rdečo, tako da lahko uporabniki zlahka vidijo, katere dele vprašanja je treba popraviti. Tako lahko opravite preverjanje na strani. Na ta način vam 'ne bo treba čakati, da uporabnik klikne na gumb za oddajo, da potrdi zadevno vprašanje.

'Veljavne vrednosti

• Vsak veljaven regularni izraz

Pogoj (prej "Enačba ustreznosti")

Opis

Če je rezultat pogoja »1« ali »true«, je vprašanje v kontekstu ankete »relevantno«, torej se prikaže anketirancu. Če ne, je vprašanje skrito. Vsako anketno vprašanje vam omogoča, da določite enačbo pomembnosti. Ta funkcija je naslednica pogojev in podpira veliko bolj zapleteno pogojno logiko.

Označevanje sintakse

Kadarkoli shranite pogoj, je ovrednoten in sintaktično poudarjen. Morebitne napake bodo označene z barvami, da jih boste lahko hitro odkrili in odpravili.

 Hint: Če želite preveriti, ali so vsi pogoji v vaši anketi pravilno uporabljeni, preberite o naši funkciji prikaži logično datoteko.

Veljavne vrednosti

• Kateri koli pogoj, ki uporablja sintakso ExpressionScript brez okoliških zavitih oklepajev.

Primeri

Tu so dobri primeri označevanja sintakse.

Napredne nastavitve

Predpona (predpona)

Opis

Besedilna vrednost, ki bo prikazana kot predpona pred poljem(-i) za vnos besedila. Predpona je prikazana levo od vnosa.

Če je zaslon majhen, bo nad vnosom prikazana predpona. Če ga želite pustiti na levi strani ^{(New in 3.0.0 )} : dodajte vprašanju razred suffix-prefix-force.

Veljavne vrednosti

• Vsak znak ali nabor znakov, ki jih želite prikazati pred vnosom

Primer

Če bi za ta atribut vnesli vrednost "$", bi bil neposredno pred poljem za vnos besedila prikazan znak za dolar.

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).

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.

Input box width (text_input_width)

Description

This attribute sets the width of the text input boxes (of the "wrapper" of the text input boxes). The input box is used to introduce an answer to the (sub)question. If the value of the width is sufficiently high, then the text input box will be displayed on the next line. Please note that this option does not set the size of the input or the width of the entire column!

Available options

• Default: If selected, a default value will be allocated to this attribute in such a way to have both the label and its corresponding text input box on the same line. For example, if the text input box width is 41%, the value of the width of the text input box will be a value that allows both the label and the input box on the same line (58% in this case). If the width of text input box was higher than 58%, then the text input box would be displayed on the next line.
• 8%; 17%...92%, 100%: the bigger the selected value, the larger the width of the text input box.

Example

• If you wish to have the input part displayed below the subquestion/label, select the 100% option from the dropdown list.

Always hide this question (hidden)

Description

If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:

• If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.
• If you wish to store or calculate a value on the fly via the ExpressionScript - Presentation.

Note: A common question type that is used with this function is the Equation one.

Available options

• On
• Off (default)

Integer only (num_value_int_only)

Description

If enabled, the respondents will be able to introduce in the box only integer values.

Available options

• Yes
• No (default)

Maximum characters (maximum_chars)

Description

This allows you to set the maximum number of characters that can be entered for a text based question. Entering a value of, say, 20 will mean that the participant cannot enter any more than 20 characters.

Valid values

• Any integer value above 0

Minimum value of the numeric input (min_num_value_n)

Description

Minimum value of the numeric input that can be introduced in the input box by the respondent.

Valid values

• Any integer value above 0
• Any number
• Any SGQA code
• Any question code (variable name)
• Any equation, using ExpressionScript syntax, without surrounding curly braces.

Maximum value of the numerical input (max_num_value_n)

Description

Maximum value of the numeric input that can be introduced in the input box by the respondent.

Valid values

• Any integer value above 0
• Any number
• Any SGQA code
• Any question code (variable name)
• Any equation, using ExpressionScript syntax, without surrounding curly braces.

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)

Show in public statistics (public_statistics)

Description

This attribute allows the survey administrator to chose if a particular question results should be displayed to the survey participants after they submitted the survey.

Note: To have the statistics displayed on the last page, do not forget to enable this functionality from the presentation & navigation settings. Otherwise, no statistics link will be displayed at the end of your survey.

The default setting for each question is 'Off' (=Do not show the question statistics to the respondents). You have to enable this for every single question if you want to show the survey statistics of that (those) particular question(s) to the survey participants after the survey submission.

Available options

• On
• Off (default)

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.

 Hint: In order to create complex validation messages, read about the usage of the ExpressionScript.

If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file: Em_validation_q_example.zip.

 Hint: Remember, LimeSuvey uses the Perl syntax for regular expressions, so they should start and end with / (slash character)!

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."
