# @ohos.promptAction (Prompt)

The **PromptAction** module provides APIs for creating and showing toasts, dialog boxes, and action menus.

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
> This module cannot be used in the file declaration of the [UIAbility](../apis-ability-kit/js-apis-app-ability-uiAbility.md). In other words, the APIs of this module can be used only after a component instance is created; they cannot be called in the lifecycle of the UIAbility.
>
> The functionality of this module depends on UI context. This means that the APIs of this module cannot be used where the UI context is unclear. For details, see [UIContext](js-apis-arkui-UIContext.md#uicontext).
>
> Since API version 10, you can use the [getPromptAction](js-apis-arkui-UIContext.md#getpromptaction) API in [UIContext](js-apis-arkui-UIContext.md#uicontext) to obtain the [PromptAction](js-apis-arkui-UIContext.md#promptaction) object associated with the current UI context.

## Modules to Import

```ts
import { promptAction } from '@kit.ArkUI';
```

## promptAction.showToast

      })
    }
  }
}

@Entry
@Component
