# Wait for a JavaScript event

Source: https://zshot-cli.com/examples/wait-for-event/
Markdown: https://zshot-cli.com/examples/wait-for-event/index.md
Section: [Examples](https://zshot-cli.com/examples/)

Capture the [Hello from ZShot](https://zshot-cli.com/example_assets/hello_zshot/) page once its `animation:complete` event fires, saved to [`hello.png`](/example-renders/wait-for-event.png).

**CLI**

```sh
zshot -f hello.png \
  --wait-for js:animation:complete \
  https://zshot-cli.com/example_assets/hello_zshot/
```

**JSON** — `POST /` body for the [API](/reference/server/api), Pro license

```json
{
  "url": "https://zshot-cli.com/example_assets/hello_zshot/",
  "output_type": "png",
  "wait_for": "js:animation:complete"
}
```

**curl**

```sh
curl -X POST http://127.0.0.1:3000/ \
  -H "Content-Type: application/json" \
  -d '{"url":"https://zshot-cli.com/example_assets/hello_zshot/","output_type":"png","wait_for":"js:animation:complete"}' \
  -o hello.png
```

Expected output: [wait-for-event.png](/example-renders/wait-for-event.png) — The Hello from ZShot page settled to its dark final frame
