Round quota to nearest multiple of 10 using Java in Qualtrics Questionnaire | XM Community
Skip to main content
Dear all, I would like to generate a question in my survey, where the current number of participants rounded to the next multiple of 10 is displayed. Qualtrics support told me I need to use Java - as I am not familiar with using Java, I'd appreciate your help! Specifically I would like to display to the participants the text: _"Number of participants so far: < X"_ Where X represents the next multiple of 10 of number of participants. I have already created a quota named "QuotaCount", which counts the number of participants of the survey. Therefore the JavaScript should generate i.e. the following: * if QuotaCount = 0 -> X=10 * if QuotaCount = 1 -> X=10 * if QuotaCount = 6 -> X=10 * if QuotaCount = 10 -> X=20 * if QuotaCount = 11 -> X=20 etc. I have found the folowing formular online: (parseInt(x / 10, 10) + 1) * 10 - not sure though how to use it in context of the java script. * Looking forward to your answers. Thank you and best regards,
Let's say your html looks like: ``` Number of participants so far: < <span id="X"></span> ``` Then add the following js to the addOnload function: ``` var quota = parseInt("${qo://quota pipe string goes here}"); jQuery("#X").html((parseInt(quota/10, 10)+1)*10); ```
Dear Tom, thank you for the quick reply. Three more questions: * do I need to type the name of my quota 'QuotaCount' wherever you have 'quota' in your code? * Do the " need to remain or do I replace them? * Is there a way to test the code without clicking through the whole survey ? Thank you very much in advance! Best regards,
Just recognized.. the HTML code: "Number of participants so far: < <span id="X"></span>" does not remain. When qualtrics saves the question it changes to: "Number of participants so far: < " - so the reference will not remain in the html code. Thank you very much in advance for your help! Best regards
> @CaBe2018 said: > * do I need to type the name of my quota 'QuotaCount' wherever you have 'quota' in your code? No, 'quota' is a JavaScript variable. You only need to pipe your 'QuotaCount' into the first line where it says '${qo://quota pipe string goes here}' > * Do the " need to remain or do I replace them? Yes, you need the quotes around your piped 'QuotaCount' > * Is there a way to test the code without clicking through the whole survey ? You can do a View Block from Block Options (helpful if your question is close to the top of the block) > Just recognized.. the HTML code: "Number of participants so far: < " does not remain. When qualtrics saves the question it changes to: "Number of participants so far: < " - so the reference will not remain in the html code. It's there, you just don't see it because the initial value inside the `<span>` is blank. It will be updated when the JS runs. You can put a placeholder inside the span (e.g., 0) if you want since it will be replaced. But the respondent may see it flash by before the actual value is set.
Hi TomG, I was able to test it and it worked! Thank you very much! Best regards,
