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.

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
.

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
.

Centered text
Use the center
attribute to center the text.
:::demo
message/centered-content
:::
Use HTML string
message
supports HTML string.
:::demo Set dangerouslyUseHTMLString
to true and message
will be treated as an HTML string.
message/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. So when dangerouslyUseHTMLString
is on, please make sure the content of message
is trusted, and never assign message
to user-provided content.
:::
Grouping
merge messages with the same content.
:::demo Set grouping
to true and the same content of message
will be merged.

:::
Global method
Element Plus has added a global method $message
for app.config.globalProperties
. So in a vue instance you can call Message
like what we did in this page.
Local import
import { ElMessage } from 'element-plus'
In this case you should call ElMessage(options)
. We have also registered methods for different types, e.g. ElMessage.success(options)
. You can call ElMessage.closeAll()
to manually close all the instances.
App context inheritance >= 2.0.3
Now message accepts a context
as second parameter of the message constructor which allows you to inject current app's context to message which allows you to inherit all the properties of the app.
You can use it like this:
:::tip
If you globally registered ElMessage component, it will automatically inherit your app context.
:::
import { getCurrentInstance } from 'vue'
import { ElMessage } from 'element-plus'
// in your setup method
const { appContext } = getCurrentInstance()!
ElMessage({}, appContext)
