Tip vprašanja - Številski vnos
From LimeSurvey Manual
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.

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.
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.
Pripona (končnica)
Opis
Besedilna vrednost, ki bo pripona k polju za vnos besedila. Pripona je prikazana tik ob vnosu.
Na majhnem zaslonu: pripona je prikazana pod vnosom. Če ga želite pustiti desno (New in 3.0.0 ) : vprašanju dodajte razred suffix-prefix-force.
Veljavne vrednosti
- Vsak znak ali nabor znakov, za katerega želite, da se prikaže po vnosu
Primer
Če bi za ta atribut vnesli vrednost »%«, bi bil takoj za poljem za vnos besedila prikazan znak za odstotek.
Skrij nasvet (hide_tip)
Opis
Večina vprašanj običajno vključuje namig, ki pravi: »Prosimo, izberite eno od naslednjih možnosti« ali besedilo z namigom, kako izpolniti vprašanje. Ta atribut vam omogoča, da izklopite ali vklopite te nasvete/namige.
Ti nasveti/namigi vključujejo sporočila o kriterijih za preverjanje (kot je najmanjše/največje število odgovorov, najmanjša/največja/enaka vrednost vsote). Če je hide_tip omogočen, bodo ta sporočila skrita. Vendar, če uporabnik vnese neveljavne podatke, se prikažejo namigi. Obarvana bodo rdeče in se bodo spremenila v zeleno, ko bodo izpolnjena merila za preverjanje veljavnosti.
'Razpoložljive možnosti
- Vklopljeno - nasveti/namigi so skriti;
- Izklopljeno (privzeto).
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.
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.
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.
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.
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."
