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.

<template>
  <el-button
    plain
    @click="open1">
    Closes automatically
  </el-button>
  <el-button
    plain
    @click="open2">
    Won't close automatically
    </el-button>
</template>

<script>
  import { h } from 'vue';

  export default {
    methods: {
      open1() {
        this.$notify({
          title: 'Title',
          message: h('i', { style: 'color: teal' }, 'This is a reminder')
        });
      },

      open2() {
        this.$notify({
          title: 'Prompt',
          message: 'This is a message that does not automatically close',
          duration: 0
        });
      }
    }
  }
</script>

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.

<template>
  <el-button
    plain
    @click="open1">
    Success
  </el-button>
  <el-button
    plain
    @click="open2">
    Warning
  </el-button>
  <el-button
    plain
    @click="open3">
    Info
  </el-button>
  <el-button
    plain
    @click="open4">
    Error
  </el-button>
</template>

<script>
  export default {
    methods: {
      open1() {
        this.$notify({
          title: 'Success',
          message: 'This is a success message',
          type: 'success'
        });
      },

      open2() {
        this.$notify({
          title: 'Warning',
          message: 'This is a warning message',
          type: 'warning'
        });
      },

      open3() {
        this.$notify.info({
          title: 'Info',
          message: 'This is an info message'
        });
      },

      open4() {
        this.$notify.error({
          title: 'Error',
          message: 'This is an error message'
        });
      }
    }
  }
</script>

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.

<template>
  <el-button
    plain
    @click="open1">
    Top Right
  </el-button>
  <el-button
    plain
    @click="open2">
    Bottom Right
  </el-button>
  <el-button
    plain
    @click="open3">
    Bottom Left
  </el-button>
  <el-button
    plain
    @click="open4">
    Top Left
  </el-button>
</template>

<script>
  export default {
    methods: {
      open1() {
        this.$notify({
          title: 'Custom Position',
          message: 'I\'m at the top right corner'
        });
      },

      open2() {
        this.$notify({
          title: 'Custom Position',
          message: 'I\'m at the bottom right corner',
          position: 'bottom-right'
        });
      },

      open3() {
        this.$notify({
          title: 'Custom Position',
          message: 'I\'m at the bottom left corner',
          position: 'bottom-left'
        });
      },

      open4() {
        this.$notify({
          title: 'Custom Position',
          message: 'I\'m at the top left corner',
          position: 'top-left'
        });
      }
    }
  }
</script>

:::

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.

<template>
  <el-button
    plain
    @click="open">
    Notification with offset
  </el-button>
</template>

<script>
  export default {
    methods: {
      open() {
        this.$notify.success({
          title: 'Success',
          message: 'This is a success message',
          offset: 100
        });
      }
    }
  }
</script>

:::

Use HTML string

message supports HTML string.

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

<template>
  <el-button
    plain
    @click="open">
    Use HTML String
  </el-button>
</template>

<script>
  export default {
    methods: {
      open() {
        this.$notify({
          title: 'HTML String',
          dangerouslyUseHTMLString: true,
          message: '<strong>This is <i>HTML</i> string</strong>'
        });
      }
    }
  }
</script>

:::

:::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. 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.

<template>
  <el-button
    plain
    @click="open">
    Hide close button
    </el-button>
</template>

<script>
  export default {
    methods: {
      open() {
        this.$notify.success({
          title: 'Info',
          message: 'This is a message without close button',
          showClose: false
        });
      }
    }
  }
</script>

Global method

Local import

Import Notification:

import { Notification } from 'element-plus';

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