## Question

I want to execute a JavaScript function within the context of another window running in io.Connect Desktop, calling a function exposed by a third-party web application hosted in the platform.

I know this can be done outside io.Connect by creating an Electron window and using the Node APIs to execute JavaScript in the `BrowserWindow`. I’d prefer to do it within io.Connect, to take full advantage of its windowing and interop capabilities. Is there a supported way to do this?

## Answer

Yes. Use the `executeCode()` method, which executes code in the context of an io.Connect Window. It is available on [`IOConnectWindow`](https://docs.interop.io/desktop/reference/javascript/windows/ioconnectwindow/index.html#IOConnectWindow-executeCode) instances and was introduced in io.Connect Desktop 9.5.

Executing JavaScript code within the context of an io.Connect Window is **disabled by default**. To enable it, set the `"allowScriptExecution"` top-level property to `true` in the app definition of the application that will execute the code:

```json
{
    "allowScriptExecution": true
}

```

To execute code, obtain a reference to the target io.Connect Window and call `executeCode()` on it, passing the code as a string. The method resolves with the result returned from the executed code, or rejects if the result of the code is a rejected `Promise`:

```javascript
const ID = "2506_04";
const ioConnectWindow = io.windows.findById(ID);
const myCode = "(() => { return 42; })()";

const result = await ioConnectWindow.executeCode(myCode);
console.log(result);

```
