Jira expressions follow technically speaking the JavaScript syntax. The most common information concerning operators (Jira expressions) and functions is listed below. To learn more about, please refer to the official documentation.

Excerpt

Comparison operators

The operators, their meaning and the applicable data types you can use them with are listed below.

value.

title	Overview of all case-sensitive comparison operators

Info
All operators respect the case of the characters.

Operator Meaning Examples (all examples return true)

==

equal to

Code Block

language	bash
linenumbers	true

1==1
true == true
[1, 2, 3] == [1, 2, 3]
["blue", "red", "green"] == ["blue", "red", "green"]

!=

not equal to

Code Block

language	bash
linenumbers	true

0 != 1
"HELLO" != "Hello"
true != false
[1, 2, 3] != [1, 3, 2]
["blue", "red", "green"] != ["blue", "green", "red"]

<

less than

Code Block

language	bash
linenumbers	true

1 < 2
"abc" < "bbc"
"abc" < "abcd"

>

greater than

Code Block

language	bash
linenumbers	true

2 > 1
"bbc" > "abc"
"abcd" > "abc"

<=

less than or equal to

Code Block

linenumbers	true

3 <= 3

>=

greater than or equal to

Code Block

language	bash

"Hello world! Hello *" >= "Hello world"

Logical operators

The table below lists an example set of logical operators that can be used for linking logical terms in an expression.

They take logical terms (which return

Status

subtle	true
title	boolean

values) as operands and can thus be built using:

a boolean value
a comparison
a logical term enclosed by brackets ()
two logical terms connected with a logical operator, where boolean values and comparisons themselves are logical terms.

Operator	Meaning	Precedence
`!`	logical negation	1 (highest)
`&&`	logical conjunction	2
`\|\|`	logical disjunction	3

UI Text Box

type	info

A single logical term can be enclosed by brackets () in order to increase the readability of the expressions or to define a precedence which differs from the given one.

Conditional operator

The conditional operator, ?-operator, is a powerful one to construct conditional expressions.

Code Block

linenumbers	true

<logical_expression> ? <term_1> : <term_2>

Expression

Description

Code Block

linenumbers	true

issue.priority.name == "Highest" ? "Please have a look at this issue immediately" : "No stress, come back later"

IF the priority of an issue is Blocker,

THEN this function will return the

Status


subtle	true
title	text

"Please have a look at this issue immediately"

ELSE it will return the

Status


subtle	true
title	text

"No stress, come back later".

Code Block

linenumbers	true

issue.somefield == "Red" ? "Color" : "No color"}

IF a custom field (e.g. a select list) has a value of Red,

THEN this function will return the text Color,

ELSE it will return No color.

(new Date()).getHours() > 21:00 || (new Date()).getHours() < 7:00 ? "Night" : "Day"

IF the current time is between 21:00 and 7:00
