# Notification

Displays a global notification message at a corner of the page.

## Basic usage

:::demo Element Plus has registered the `$notify` method and it receives an object as its parameter. In the simplest case, you can set the `title` field and the` message` field for the title and body of the notification. By default, the notification automatically closes after 4500ms, but by setting `duration` you can control its duration. Specifically, if set to `0`, it will not close automatically. Note that `duration` receives a `Number` in milliseconds.

## With types

We provide four types: success, warning, info and error.

:::demo Element Plus provides four notification types: `success`, `warning`, `info` and `error`. They are set by the `type` field, and other values will be ignored. We also registered methods for these types that can be invoked directly like `open3` and `open4` without passing a `type` field.

:::

## Custom position

Notification can emerge from any corner you like.

:::demo The `position` attribute defines which corner Notification slides in. It can be `top-right`, `top-left`, `bottom-right` or `bottom-left`. Defaults to `top-right`.

notification/positioning

:::

## With offset

Customize Notification's offset from the edge of the screen.

:::demo Set the `offset` attribute to customize Notification's offset from the edge of the screen. Note that every Notification instance of the same moment should have the same offset.

:::

## Use HTML string

`message` supports HTML string.

:::demo Set `dangerouslyUseHTMLString` to true and `message` will be treated as an HTML string.

notification/raw-html

:::

:::warning

Although `message` property supports HTML strings, dynamically rendering arbitrary HTML on your website can be very dangerous because it can easily lead to [XSS attacks](https://en.wikipedia.org/wiki/Cross-site_scripting). So when `dangerouslyUseHTMLString` is on, please make sure the content of `message` is trusted, and **never** assign `message` to user-provided content.

:::

## Hide close button

It is possible to hide the close button

:::demo Set the `showClose` attribute to `false` so the notification cannot be closed by the user.

notification/no-close

:::

## Global method

Element Plus has added a global method `$notify` for `app.config.globalProperties`. So in a vue instance you can call `Notification` like what we did in this page.

## Local import

```javascript
import { ElNotification } from 'element-plus'
```

In this case you should call `ElNotification(options)`. We have also registered methods for different types, e.g. `ElNotification.success(options)`. You can call `ElNotification.closeAll()` to manually close all the instances.

## App context inheritance <el-tag>> 2.0.4</el-tag>

Now notification accepts a `context` as second parameter of the message constructor which allows you to inject current app's context to notification which allows you to inherit all the properties of the app.

You can use it like this:

:::tip

If you globally registered ElNotification component, it will automatically inherit your app context.

:::

```ts
import { getCurrentInstance } from 'vue'
import { ElNotification } from 'element-plus'

// in your setup method
const { appContext } = getCurrentInstance()!
ElNotification({}, appContext)
```
