Set Field Value Action
A set field action requires the selection of a form field and a "value" that will be set into the field.
A set field action requires the selection of a form field and a "value" that will be set into the field. The "value" can be either:
A specific value that may be a number, some text, true/false, etc.
An expression that combines specific values and/or fields using arithmetic/text/logic operators and optionally parenthesis.
To support the above possibilities, set field actions support both a value entry "mode" and an expression entry "mode". Set field actions will always start in value entry mode. In value entry mode you may simply enter a number or text or if the field is a select type field, select one of the select options.
The set field actions have an overflow menu (3-dot icon) that has an option to put the input into expression input mode (see above). In expression input mode, enter specific values and/or select fields and combine them with operators and parenthesis as needed.
Here are some very simple examples:
Expression Operators
The following operators are supported in expressions. Parenthesis are also supported for numeric expressions.
Operator | Name | Purpose | Example |
+ | Addition | Add two numeric sub-expressions | a + b |
- | Subtraction | Subtract two numeric sub-expressions | a - b |
* | Multiplication | Multiply two numeric sub-expressions | a * b |
/ | Division | Divide two numeric sub-expressions | a / b |
+ | Concatenation | Concatenate two text sub-expressions | firstName + " " + lastName |
==, === | Equality | Compare two sub-expressions for equality | a == b |
!=, !== | Inequality | Compare two sub-expressions for inequality | a !== b |
> | Greater than | Compare two sub-expressions for greater than | a > b |
>= | Greater than or equal | Compare two sub-expressions for greater than or equal | a >= b |
< | Less than | Compare two sub-expressions for less than | a < b |
<= | Less than or equal | Compare two sub-expressions for less than or equal | a <= b |
