Hi community,

is there an option (I guess with javascript) to remove the inputs (the answers given by respondents) from a multiple choice and multiple numerical input question when the question gets "hidden" because the question is currently not relevant (concerning relevance equation). So to say data cleaning.
In other words, when a question was answered, but then the relevance equation changes to wrong (not relevant), the question becomes hidden, and then the answer input of respondents in the question should be removed (cleaned).

LS Version 3.14

There is no JavaScript method to detect when an element is hidden or to detect class changes so you would need to put listeners on the questions that are triggering the relevance change. These listeners (and the resulting callbacks) would vary depending on the question types and IDs.

Having said that, I don't see what the problem is. The answers in irrelevant questions only persist until the survey page (group) is submitted.

Sorry Tony,

Currently :
Relevance updated (set to on/off) : github.com/LimeSurvey/LimeSurvey/blob/2f...survey/survey.js#L24
Class change due to error : github.com/LimeSurvey/LimeSurvey/blob/ma...urvey/survey.js#L342

Else :

It's the case (by default) when move next only, then if user check a input:checkbox by error , it don't loose previous answer.
Why do you want to clean previous value ?

@DenisChenu, no need to apologize. Do you have a solution?

Hi,

sorry, I didn't know that the previous values are cleaned anyway by clicking next. In that case everything is fine. I just thought that I need to remove the answers of hidden questions afterwards in the data analysis in spss. Thank you.

I think we don't need solution, since LS behaviour cleanup value when move next.

But else : usage of on(!relevance:off' can do the trics

Hi,

can you please tell me where to insert this '!relevance:off'. I would need the solution yet because I have this question multiple numeric question where the answer option 'thereof irrigated' is showed when 'cropland' is > 0. But when respondents type something in 'thereof irrigated' and then change back 'cropland' to 0 they cannot proceed further because 'thereof irrigated' cannot be greater than 'cropland' (I did it with max value of the <input type="number"> field). In that case the answer option 'thereof irrigated' is hidden (if it is shown, it would have a red background) and the respondent doesn't know why he cannot proceed.

'thereof irrigated' cannot be greater than 'cropland':


when 'cropland' is 0 and 'thereof irrigated' has a value inside, respondents cannot proceed:

Can you send a lss with just this question ?

I think it must work out of the box, but maybe validation of question must be fixed .

It's your script to fix :

Sure, never thought about a simple else statement
I'm sorry that I did not have this idea before.
