Message

Used to show feedback after an activity. The difference with Notification is that the latter is often used to show a system level passive notification.

Basic usage

Displays at the top, and disappears after 3 seconds.

:::demo The setup of Message is very similar to notification, so parts of the options won't be explained in detail here. You can check the options table below combined with notification doc to understand it. Element has registered a $message method for invoking. Message can take a string or a VNode as parameter, and it will be shown as the main body.

<template>
  <el-button :plain="true" @click="open">Show message</el-button>
  <el-button :plain="true" @click="openVn">VNode</el-button>
</template>

<script>
  export default {
    methods: {
      open() {
        this.$message('This is a message.');
      },

      openVn() {
        const h = this.$createElement;
        this.$message({
          message: h('p', null, [
            h('span', null, 'Message can be '),
            h('i', { style: 'color: teal' }, 'VNode')
          ])
        });
      }
    }
  }
</script>

Types

Used to show the feedback of Success, Warning, Message and Error activities.

:::demo When you need more customizations, Message component can also take an object as parameter. For example, setting value of type can define different types, and its default is info. In such cases the main body is passed in as the value of message. Also, we have registered methods for different types, so you can directly call it without passing a type like open4.

<template>
  <el-button :plain="true" @click="open2">success</el-button>
  <el-button :plain="true" @click="open3">warning</el-button>
  <el-button :plain="true" @click="open1">message</el-button>
  <el-button :plain="true" @click="open4">error</el-button>
</template>

<script>
  export default {
    methods: {
      open1() {
        this.$message('This is a message.');
      },
      open2() {
        this.$message({
          message: 'Congrats, this is a success message.',
          type: 'success'
        });
      },

      open3() {
        this.$message({
          message: 'Warning, this is a warning message.',
          type: 'warning'
        });
      },

      open4() {
        this.$message.error('Oops, this is a error message.');
      }
    }
  }
</script>

:::

Closable

A close button can be added.

:::demo A default Message cannot be closed manually. If you need a closable message, you can set showClose field. Besides, same as notification, message has a controllable duration. Default duration is 3000 ms, and it won't disappear when set to 0.

<template>
  <el-button :plain="true" @click="open1">message</el-button>
  <el-button :plain="true" @click="open2">success</el-button>
  <el-button :plain="true" @click="open3">warning</el-button>
  <el-button :plain="true" @click="open4">error</el-button>
</template>

<script>
  export default {
    methods: {
      open1() {
        this.$message({
          showClose: true,
          message: 'This is a message.'
        });
      },

      open2() {
        this.$message({
          showClose: true,
          message: 'Congrats, this is a success message.',
          type: 'success'
        });
      },

      open3() {
        this.$message({
          showClose: true,
          message: 'Warning, this is a warning message.',
          type: 'warning'
        });
      },

      open4() {
        this.$message({
          showClose: true,
          message: 'Oops, this is a error message.',
          type: 'error'
        });
      }
    }
  }
</script>

:::

Centered text

Use the center attribute to center the text.

:::demo

<template>
  <el-button :plain="true" @click="openCenter">Centered text</el-button>
</template>

<script>
  export default {
    methods: {
      openCenter() {
        this.$message({
          message: 'Centered text',
          center: true
        });
      }
    }
  }
</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="true" @click="openHTML">Use HTML String</el-button>
</template>

<script>
  export default {
    methods: {
      openHTML() {
        this.$message({
          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. :::

Global method

Element has added a global method $message for Vue.prototype. So in a vue instance you can call Message like what we did in this page.

Local import

Import Message:

import { Message } from 'element-ui';

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

Options

Attribute	Description	Type	Accepted Values	Default
message	message text	string / VNode	—	—
type	message type	string	success/warning/info/error	info
iconClass	custom icon's class, overrides type	string	—	—
dangerouslyUseHTMLString	whether message is treated as HTML string	boolean	—	false
customClass	custom class name for Message	string	—	—
duration	display duration, millisecond. If set to 0, it will not turn off automatically	number	—	3000
showClose	whether to show a close button	boolean	—	false
center	whether to center the text	boolean	—	false
onClose	callback function when closed with the message instance as the parameter	function	—	—
offset	set the distance to the top of viewport	number	—	20

Methods

Message and this.$message returns the current Message instance. To manually close the instance, you can call close on it.
