Code to restrict change of custom field

Narsha Bachoo

Hello Team,

I am trying to write a code on scriptrunner to restrict the change of a custom field. The user must not be able to change the value lesser than the actual value. For e.g., if the field's value is 20%, the user cannot change it to 10%. He should be able to change it to values which is greater than 20%. The custom field is a Select List (single choice) type and the name of the custom field is 'Percentage Completion'.

Can you help please?

Thanks,

Narsha

Hey @Narsha Bachoo ,

This looks like something which could be achieved using ScriptRunner's behaviours. The script will need some editing to match your instance needs but do give it a play around.

The setup used (On load , Issue View) because you are editing the issue right?

const percentageCompletionField = getFieldById('YOUR_CF_ID');
const currentPercentageValue = percentageCompletionField.getValue().value.replace('%', '');

//I have % in my context values so this is just removing it for comparison

const currentPercentage = parseInt(currentPercentageValue); 

//This portion is about your option ID and converted values..examples..

const optionVisibilities = {
'10101': 10, // this is for 10%
'10102': 20, // this is for 20%
'10103': 30, // this is for 30%
//and so forth...it would absolutely be possible for you to just use numbers instead of how I did mine

};

//This hides the visibility of the options available on load based on the original select list value (eg: 30%, then wont be able to see 10% and 20%)

const optionsToHide = Object.keys(optionVisibilities).filter(optionId => optionVisibilities[optionId] < currentPercentage);
percentageCompletionField.setOptionsVisibility(optionsToHide, false);

This is what my Select List CF looks like when the issue already have 30% selected and I am trying to change it:

One thing to be aware, this applies for everyone. So, if you want to restrict it to some user groups or users etc, then check out this sample Make field read-only based on user groups and adapt it to your needs.

Hope that helps!
