Formulas in a grid

This page describes formulas functionality in the Table Grid Editor for Jira Cloud. 

A Formula is a separate column type based on JavaScript. Add a separate column using formula column type, input formula inside embedded JavaScript Ace Editor and get results on the grid. The grid can process formula logic and aggregate formula results.

Formula column type

You can add a formula as a separate column in a grid by selecting the formula column type. The column uses JavaScript to create formulas. 

Formula expressions - editor, where you can input JavaScript formula code. It uses Ace Editor, which highlights the syntax.

Formulas as an aggregation function

You can use formula as an aggregation operation in other columns.

It provides you the flexibility to operate grid data in different ways. 

This feature is available for all column types, supported by the Table Grid Next Generation for Jira Cloud.

Formula expressions

In order to display formula result in the grid column input JS expression in the formula expression configuration.

You can do following operations using formulas: 

• string concatenation;

• mathematical operations with numbers: addition, subtraction, multiplication, division; 
  

• date subtraction - it's possible to use Moments.js library;

• conditions

• userlist operation

Formula syntax

You can create a formula using JavaScript. The column ID is a variable, use it in the following format: $(yourColumnId).

Use return as a keyword to get the formula result.

return $(user).value

return $(firstStringColumnId) + ' ' + $(secondStringColumnId);

//Numbers and Integer column type
return $(numb1) * $(numb2) return $(numb1) / $(numb2) return $(numb1) + $(numb2) return $(numb1) - $(numb2) return Math.abs()

if($(check) || $(role) === 'Team lead'){ return $(numb1) * $(numb2) } else { return $(numb1) / $(numb2) / 0 }

firstDate = moment($(firsdt)); 
var secondDate = moment($(seconddt)); 
var difference = firstDate.diff(secondDate); 
return Math.abs(moment.duration(difference).asDays());

Examples

Below you can find formula examples with most common expressions.

Condition with numbers

This example shows how to provide exam results, based on the conditions specified in the formula. You can use conditions in the formula with all available column types.

var correctPercent = $(correct) * 100 / $(total)
var result = ''
if($(level) === 'low') {
 result = correctPercent > 60 ? 'Passed' : 'Fail'
} else if ($(level) === 'medium') {
 result = correctPercent > 70 ? 'Passed' : 'Fail'
} else {
 result = correctPercent > 80 ? 'Passed' : 'Fail'
}
return result

Date subtraction

This example shows how to subtract Date. You can use Date, Time, DateTime column types.

var firstDate = moment($(startDate));
var secondDate = moment($(endDate));
var difference = firstDate.diff(secondDate);
return Math.abs(moment.duration(difference).asDays());

Checkbox

This example shows how to use checkbox column type in condition formula. 

if($(calculate)){
    return $(salary) + $(bonus)
} else {
    return $(salary)
}

Numbers

This example shows how to use JavaScript Math. 

var sum = $(a) + $(b)
if(sum > 1000) {
    return sum * $(coefficient)
} else {
    return sum / $(coefficient)
}

String concatenation

This example shows how to concatenate string column type. 

return $(user) + ' ' + $(position)
