## Execute Script Return Values
|
|
|
|
When using `browser.scripting.executeScript`, you can execute content scripts or unlisted scripts. To return a value, just return a value from the script's `main` function.
|
|
|
|
```ts
|
|
// entrypoints/background.ts
|
|
const res = await browser.scripting.executeScript({
|
|
target: { tabId },
|
|
files: ['injected.js'],
|
|
});
|
|
console.log(res); // "Hello John!"
|
|
```
|
|
|
|
```ts
|
|
// entrypoints/injected.js
|
|
export default defineUnlistedScript(() => {
|
|
console.log('Script was injected!');
|
|
return 'Hello John!';
|
|
});
|
|
```
