Can I use JavaScript to make all input types into numbers that are shown in Thunkable Web Viewer ?

Do I need to use this tool?

How can I put my JavaScript code in this box?

Hello @eak41  
We replied to your question in a separate support channel but I also wanted to offer the answer here.

To add a JavaScript code inside a Thunkable app you can use a [“JavaScript Web Bridge” block](https://docs.thunkable.com/blocks/advanced-app-features/javascript-web-bridge) or [Web Viewer component.](https://docs.thunkable.com/app-design/ui-components/embed-components/web-viewer)

In both ways, the code needs to be saved as an HTML that inside contains the JavaScript code

Further setup instructions here: [Thunkable Web Viewer Extensions](https://github.com/thunkable/webviewer-extension/).
