I would like trigger an action when a text field is active.

It works using **click** event with the mouse.

But with **tab** key it is not working.

```
name() {
  console.log('selected field => name')
}

<div data-action="focus->user#name click->user#name">
  <%= form.label :name %>
  <%= form.text_field :name, autofocus: true %>
</div>

```

What is the correct way to use focus in a rails form?

The `focus` event doesn’t bubble so it can’t be handled on a parent element. You could:

- Move the `focus->user#name` action to the text field
- Switch to handling [`focusin`](https://developer.mozilla.org/en-US/docs/Web/API/Element/focusin_event) instead

> The `focusin` event fires when an element is about to receive focus. The main difference between this event and [`focus`](https://developer.mozilla.org/en-US/docs/Web/API/Element/focus_event) is that `focusin` bubbles while `focus` does not.

`focusin` worked just perfect

thank you
