Overview
In noKodr, Variables are data placeholders that can be used to store and manipulate values within the application. Interaction between different components, workflows, and events. Variables can be used to pass data between different parts of the application, control logic in workflows, and adjust how components display or behave.
Note: You may encounter precreated variables within the system. These prebuilt variables are locked, meaning they cannot be modified or deleted. They are provided as reference points to assist you in creating new variables. You can use these precreated variables as templates, making necessary modifications to fit your requirements, such as adding the required fields to your forms.
Key Uses of Variables:
Data Storage: Store values such as user inputs, calculations, or data retrieved from external sources.
Dynamic Content: Use variables to dynamically update content on the layout based on user interactions or other event triggers.
Workflow Control: Control the flow of processes in workflows by using variables to make decisions, trigger actions, or modify data.
Component Interaction: Pass data between components, allowing them to interact and respond to changes in real time.
Variables are essential for creating flexible and dynamic applications in noKodr, enabling more sophisticated and responsive designs.
Variable Config:
Field Name | Description |
|---|---|
Label | A user-friendly name for the variable, used for easy identification within the application. |
Name | The unique identifier for the variable, typically used in code or within merge text. |
Field Type | Specifies the type of data the variable will hold (e.g., text, number, date,etc). Reference: Field Types |
Default Value | The initial value assigned to the variable, applied if no other value is provided. |
Is Array | Checkbox that indicates whether the variable can store multiple values (an array) instead of just one. |
Variable Scope | The Variable Scope defines the accessibility of the variable, with the following options: In: The variable is used to receive input from another layout. Out: The variable is used to pass data from the current layout to another layout. In/Out: The variable is used for both input into and output from a layout, allowing for full bidirectional data flow. |
Field Types:
Data Type | Description |
|---|---|
Text | Stores a string of characters, such as names or descriptions. |
Checkbox | Represents a boolean value (true/false) typically used for on/off or yes/no selections. |
Integer | Holds whole numbers without decimals, used for counting or numerical calculations. |
Double | Stores numbers with decimals, allowing for more precise calculations. |
Record | Represents a single Salesforce record, such as an account or contact. |
Object | Stores complex data structures or objects, often containing multiple fields or properties. |
Currency | Used to represent monetary values, ensuring proper formatting and calculations. |
Date | Stores a calendar date (year, month, day) without time information. |
DateTime | Stores both date and time information together. |
Picklist | A dropdown menu that allows users to select a single value from a predefined list. |
Tags | Stores a list of keywords or labels used for categorization or filtering. |
Specifically formatted to store email addresses. | |
Phone | Holds phone numbers, often with specific formatting. |
URL | Stores web addresses (Uniform Resource Locators) for linking to external resources. |
Radio | Represents a group of mutually exclusive options where only one can be selected. |
Time | Stores time information without an associated date. |
Percentage | Stores numerical values represented as percentages, often used in calculations or metrics. |
Text Area | Allows for the input of larger amounts of text, often used for comments or detailed descriptions. |
Duration | Stores a length of time, typically used for measuring intervals or time spans. |
Multi Picklist | Allows users to select multiple values from a predefined list. |
For Example,
Calculating and Displaying Order Totals
For instance, you might define variables like ItemPrice, Quantity, and Discount. As users input the quantity of items they want to purchase and apply a discount code, the variables update instantly. The total cost, stored in a variable named TotalAmount, is then displayed on the page, reflecting the latest calculations.
This use case demonstrates how Variables can be employed to perform real-time calculations and display updated results, enhancing the user's interaction with the application.
