How do i send multiple data items from the recives message block for webviewer extension

Questions about Thunkable

I’m currently working on a project where I use the Thunkable WebViewer Extension to communicate between my Thunkable app and a web page. I have successfully sent and received messages, but I’m facing a challenge when trying to send and receive multiple data items.

In my web app, I’m sending an object with several properties using the ThunkableWebviewerExtension.postMessage function. However, on the Thunkable side, when I receive the message in the “When WebViewer receives message” block, I’m struggling to access and display each individual property.

Here’s a simplified version of my current setup:

fetch(‘/run_script’, {
method: ‘POST’,
headers: {
‘Content-Type’: ‘application/json’
},
body: JSON.stringify({
username,
password
})
})
.then(response => response.json())
.then(data => {

                const outputArray = data.output;

                // Display each element separately
                document.getElementById('result').innerText =
                    `Smart Schedule Sync Complete. 
                    Token: ${outputArray[0]},
                    Username: ${outputArray[1]},
                    Cookies: ${outputArray[3]}`;

                ThunkableWebviewerExtension.postMessage(outputArray[0]);
                ThunkableWebviewerExtension.postMessage(outputArray[1]);
                

                    
            })
            .catch(error => {
                document.getElementById('result').innerText = "Error: " + error;
            })
            .finally(() => {
                loadingScreen.style.display = 'none';
                runScriptButton.disabled = false;
            });
    });

in thunkable it only shows the first data item ThunkableWebviewerExtension.postMessage(outputArray[0]);
and also sets my other label that i have on thunkable to ThunkableWebviewerExtension.postMessage(outputArray[0]);

Probably getting called too quick.

I would pass back the array of two items and parse it in the app

I need to send:
Token: ${outputArray[0]},Username: ${outputArray[1]}, Password: ${outputArray[2]}

however when I try to send a post message from thunkable it only sends one message and if i needed to send all 3 i would just need one VERY long string variable

Post the object back to your app, dude. That’s what you’ll do here
