Hello all, I wanted to know if Javascript works in the WebViewer of the Thunkable X Platform. It doesn´t look like it works because I get the error 101 when trying to use javascript. I wanted to use Taifun´s Tutorial how to inject text into the website and click a button using Javascript because it is, as far as I know, the only option to encrypt/decrypt text with AES in the Thunkable X Platform. I use these blocks: ![AES](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/d/dd8ed27f7b451f937602b37e54657f853fbf7c47.jpeg) Thank you for your help Nico ---

I tried this approach but I’m not quite sure if I did something wrong or if this doesn’t work in thunkable X. Here’s a link to the project, if you can help. I need to run JS in Thunkable to include a JS UUID generator: [https://x.thunkable.com/projects/5e9c380d1993a119fb61a172/a6f96313-07b0-4b6a-a70b-8421c5cb8443/designer](https://x.thunkable.com/projects/5e9c380d1993a119fb61a172/a6f96313-07b0-4b6a-a70b-8421c5cb8443/designer) ---

At the same designer link, I’m trying to update your sample code to produce a new uuid on button click. I don’t know if I’m making a typo or have a misunderstanding of nested JS functions and variable declaration/scope …or both. Your help is appreciated! ---

Here are 3 working examples of the app interacting with JavaScript. The js file could be hosted locally I believe and the concept still work. > **[GitHub - thunkable/webviewer-extension: Communicate between the Thunkable Web...](https://github.com/thunkable/webviewer-extension)** > > Communicate between the Thunkable Web Viewer and a website - GitHub - thunkable/webviewer-extension: Communicate between the Thunkable Web Viewer and a website An expanded example of above > **[jaredgibb.xyz](http://jaredgibb.xyz/thunkable/chartingwiththunkable/)** > > This domain may be for sale! ---

Hello Is there a way to generate an Object ID (similar to UUID) from within x.Thunkable for use with a POST API call to a MongoDB (\_id)? I know that if the \_id is NOT present, Mongo creates one for me, but I need this \_id to continue with a PUT statement. Any help would be appreciated. thanks ---

Create a local table using the Data Sources option and whenever you need a UUID just create a row in the local table and get the UUID from it. ---

You should already have the ID if you are making a PUT call., else, you wouldn’t know what you were PUTing. Right? ---
