The sendJoke function automates the process of fetching two jokes and posting them as separate Facebook messages within a designated browser window using Selenium WebDriver.

Run example

npm run import -- "send a joke"

send a joke

function sendJoke(client, hwnd) {
    var joke;
    return client
        .then(() => getJoke())
        .then(r => joke = r)
        .switchToWindow(hwnd)
        .then(() => sendFacebookMessage(joke[0]))
        .pause(20000)
        .then(() => sendFacebookMessage(joke[1]))
}
module.exports = sendJoke;

/**
 * Sends a joke to a client using Facebook Messenger.
 * 
 * @param {Client} client - The client object with methods for sending messages.
 * @param {number} hwnd - The handle of the window to switch to.
 * @returns {Promise} A promise that resolves when the joke has been sent.
 */
async function sendJoke(client, hwnd) {
    // Get a joke from the joke retrieval service
    const [joke1, joke2] = await getJokes();
    
    // Switch to the window and send the jokes
    await client.switchToWindow(hwnd);
    await sendFacebookMessage(client, joke1);
    await sendFacebookMessage(client, joke2);
}

// Refactored to use async/await for better readability
async function getJokes() {
    // Assume this is the implementation of getJoke() with a minor refactor
    // to return an array of jokes
    try {
        const jokes = await getJoke();
        return [jokes[0], jokes[1]];
    } catch (error) {
        console.error('Error fetching jokes:', error);
        throw error;
    }
}

// Refactored to use async/await for better readability
async function sendFacebookMessage(client, message) {
    try {
        // Send the message using the client
        await client.sendMessage(message);

        throw error;
    }
}

module.exports = sendJoke;

This code defines a function called sendJoke that sends two jokes to a Facebook message in a specific browser window.

Here's a breakdown:

1. sendJoke(client, hwnd):

   • Takes a client object (likely Selenium WebDriver) and a window handle (hwnd) as input.

2. Get a Joke:

   • Uses getJoke() (not shown in the code) to fetch a joke.
   • Stores the joke in the joke variable.

3. Switch to Window:

   • Switches the Selenium WebDriver to the specified window using switchToWindow(hwnd).

4. Send First Joke:

   • Sends the first joke from the joke array using sendFacebookMessage(joke[0]).

5. Pause:

   • Pauses for 20 seconds using pause(20000).

6. Send Second Joke:

   • Sends the second joke from the joke array using sendFacebookMessage(joke[1]).

7. Export:

   • Exports the sendJoke function for use in other parts of the code.

In essence, this function automates the process of fetching two jokes and posting them as separate Facebook messages within a specific browser window.
