# Confirm Before Closing

> Ask users to confirm before a Driver.js tour closes early, or stop them from leaving a tour they have to finish.

Use this when leaving halfway would lose something, like a setup the user has to finish. Ask before the tour closes early, or take the way out away entirely.

## Confirm on Exit

`onDestroyStarted` runs when the tour is about to end. Once you set it, the tour only ends when you call `destroy()`. The example only asks when the user leaves early.

```js
import { driver } from "driver.js";
import "driver.js/dist/driver.css";

const driverObj = driver({
  steps: [
    { element: "#search", popover: { title: "Search" } },
    { element: "#export", popover: { title: "Export" } },
  ],
  onDestroyStarted: (element, step, { reason }) => {
    if (reason === "done" || confirm("Are you sure?")) {
      driverObj.destroy();
    }
  },
});

driverObj.drive();
```

`reason` tells a finished tour (`"done"`) apart from one the user is leaving. Use your own modal instead of `confirm()` the same way: call `destroy()` when the user agrees.

## Prevent Exit

`allowClose: false` removes the close button and turns off Escape and overlay clicks, so the only way out is to finish the tour.

```js
const driverObj = driver({
  allowClose: false,
  showProgress: true,
  steps: [
    { element: "#search", popover: { title: "Search" } },
    { element: "#export", popover: { title: "Export" } },
  ],
});

driverObj.drive();
```

To keep the close button and only ignore clicks on the overlay, use `overlayClickBehavior: "none"` instead.
