Validating Checkboxes using JMWE

[Ricardo Gomes]

Hi,

I have a Jira form using checkboxes, so for each question I basically have:

Form checklist question:

[ ] N/A

[ ] Option 1

[ ] Option 2

[ ] Option 3

So upon submission, I need to validate the following:

1) Form can't be submitted empty (w/o selecting any options)

2) Form can't be submitted without selecting either "N/A" or at least one other option from options 1/2/3. 

So we must consider:

- 2.1) IF "N/A" is selected, no other option can be selected and submitted

- 2.2) IF "N/A" is not selected then I have to have at least one other option selected

I was able to accomplish #1 above with the following:

(! issue.customfield_1 || issue.customfield_1.length > 0) && (! issue.customfield_2 || issue.customfield_2.length > 0) && so on...

Now, to accomplish #2, I've tried the following (1 field example):

(!!issue.customfield_1 && issue.customfield_1.some(it => it.value == "N/A")) && (!!issue.customfield_1 && issue.customfield_1.length = 1)

which is attempting to validate "IF N/A checkbox is selected AND the count on the number of checkboxes select = 1 THEN pass the validation" BUT this doesn't seem to be working...

What am I missing? Or what's the best path to validate this?

Thank you!

Hi,

for #1, I believe you want this instead:

!! issue.customfield_1 && issue.customfield_1.length > 0 && !! issue.customfield_2 && issue.customfield_2.length > 0

which forces each field to be non-empty.

As for #2, focusing on a single field first, and already knowing from #1 that no field is empty:

issue.customfield_1.some(it => it.value == "N/A") && issue.customfield_1.length == 1
|| !issue.customfield_1.some(it => it.value == "N/A")

Combining the two:

 !! issue.customfield_1 && issue.customfield_1.length > 0 && !! issue.customfield_2 && issue.customfield_2.length > 0
&& issue.customfield_1.some(it => it.value == "N/A") && issue.customfield_1.length == 1
|| !issue.customfield_1.some(it => it.value == "N/A")
&& issue.customfield_2.some(it => it.value == "N/A") && issue.customfield_2.length == 1
|| !issue.customfield_2.some(it => it.value == "N/A")

If you end up with an expression that's too long (Jira expressions are limited to 1000 characters if I remember correctly) , you can always create a validator per field instead (which will also make error messages clearer).

Thanks, David! 

That worked. I just had an issue with the size but broke it down to several validators which solved the problem.

Cheers!
