Class Usage

How to create an instance of the FormMessage class:

TypeScript

// Create an instance of APIAction
let apiAction = new APIAction("https://example.com/api", "POST");

// Create an instance of ButtonElement
let submitButton = new ButtonElement("1", apiAction, "Submit");

// Create an instance of TextInput
let nameInput = new TextInput("1", "Please enter your name");
// Create a new instance of FormMessage

let formMessage = new FormMessage("receiverId", CometChat.RECEIVER_TYPE.USER, "Title", [nameInput], submitButton);

Key Properties and Methods

Goal Completion Text

The setGoalCompletionText() method sets the goal completion text of the form.

TypeScript

let formMessage = new FormMessage("receiverId", CometChat.RECEIVER_TYPE.USER, "Title", [nameInput], submitButton);
formMessage.setGoalCompletionText("Goal completed");

Creating a FormMessage from JSON

The static fromJSON() method creates an instance of FormMessage from a provided JSON object.

TypeScript

// Create a FormMessage from JSON
let json = { 
    receiver: "receiverId",
    receiverType: CometChat.RECEIVER_TYPE.USER,
    type: "form",
    data: {
        interactiveData: {
            title: "Title",
            formFields: [],
            submitElement: new ButtonElement("1", new APIAction("https://example.com/api", "POST"), "Submit")
        }
    }
};

let formMessageFromJSON = FormMessage.fromJSON(json);

Example

Below is an example that showcases the creation and manipulation of an instance of FormMessage:

TypeScript

// Create an instance of APIAction

let apiAction = new APIAction("https://example.com/api", "POST");

// Create an instance of ButtonElement

let submitButton = new ButtonElement("1", apiAction, "Submit");

// Create a new instance of FormMessage

let formMessage = new FormMessage("receiverId", CometChat.RECEIVER_TYPE.USER, "customType", "Title", [], submitButton);

formMessage.setGoalCompletionText("Goal completed");

// Create a FormMessage from JSON

let json = { 
    receiver: "receiverId",
    receiverType: CometChat.RECEIVER_TYPE.USER,
    type: "form",
    data: {
        interactiveData: {
            title: "Title",
            formFields: [],
            submitElement: new ButtonElement("1", new APIAction("https://example.com/api", "POST"), "Submit")
        }
    }
};

let formMessageFromJSON = FormMessage.fromJSON(json);

In this example, a new instance of the FormMessage class is created. The title, form fields, submit element, and goal completion text are retrieved, updated, and retrieved again. Then a new FormMessage instance is made from a JSON object, and the title is retrieved and logged.
