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 Plus 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 Plus 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-plus';
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.
