You can work with HTML and JavaScript using a URL but when the code is part of the project assets it will work using the computer but not using the mobile app.

Ok thanks for the reply. Is it possible to devide the html code and javascript code like below, and then fetch the javascript result with block logic?

No, this arrangement will not work. You need to create your HTML and JS script in a location where you can reach it as URL.

I have solved this on my own.

If you would like to get result from javascript you use the following block;

And then you add the following code in your .html file;

script src=“[https://thunkable.github.io/webviewer-extension/thunkableWebviewerExtension.js](https://thunkable.github.io/webviewer-extension/thunkableWebviewerExtension.js)” type=“text/javascript”\>\</script

ThunkableWebviewerExtension.postMessage(yourvalue);
