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.
