Checkbox Element

The CheckboxElement class aids in creating checkbox input elements in a user interface.

Constructor

Name	Type	Description
elementId	string	Accepts the ID for the element in the constructor
label	string	Accepts the label for checkbox in the constructor
options	Array<OptionElement>	Accepts options for checkbox in the constructor

Class Usage

Here’s how to create an instance of the CheckboxElement class:

TypeScript

let option1 = new OptionElement("Option 1", "1");

let option2 = new OptionElement("Option 2", "2");

let optionsList = [option1, option2];

let checkboxElement = new CheckboxElement("1", "Choose options", optionsList);

In this example, a new instance of CheckboxElement is created with an elementId “1”, a label “Choose options”, and a list of two options.

Key Properties and Methods

Default Value of the Input Element

The setDefaultValue() method sets the default value(s) in the checkbox input, while the getDefaultValue() retrieves it.

For example

TypeScript

checkboxElement.setDefaultValue(["1", "2"]);

Example

Here is an example that showcases the creation and manipulation of an instance of CheckboxElement:

TypeScript

// Create some options

let option1 = new OptionElement("Option 1", "1");

let option2 = new OptionElement("Option 2", "2");

let optionsList = [option1, option2];

// Create a new instance of CheckboxElement

let checkboxElement = new CheckboxElement("1", "Choose options", optionsList);

// Set and get the default value

checkboxElement.setDefaultValue(["1", "2"]);
