Loading
Show animation while loading data.
Loading inside a container
Displays animation in a container (such as a table) while loading data.
:::demo Element Plus provides two ways to invoke Loading: directive and service. For the custom directive v-loading
, you just need to bind a boolean
value to it. By default, the loading mask will append to the element where the directive is used. Adding the body
modifier makes the mask append to the body element.

Customization
You can customize loading text, loading spinner and background color.
:::demo Add attribute element-loading-text
to the element on which v-loading
is bound, and its value will be displayed under the spinner. Similarly, the element-loading-spinner / element-loading-svg
and element-loading-background
attributes are used to set the svg icon, background color value, and loading icon, respectively.
loading/customization
:::
:::warning
Although the element-loading-spinner / element-loading-svg
attribute supports incoming HTML fragments, it is very dangerous to dynamically render arbitrary HTML on the website, because it is easy to cause XSS attack. Please make sure that the content of element-loading-spinner / element-loading-svg
is trustworthy. Never assign user-submitted content to the element-loading-spinner / element-loading-svg
attribute.
:::
Full screen loading
Show a full screen animation while loading data.
:::demo When used as a directive, a full screen Loading requires the fullscreen
modifier, and it will be appended to body. In this case, if you wish to disable scrolling on body, you can add another modifier lock
. When used as a service, Loading will be full screen by default.

Service
You can also invoke Loading with a service. Import Loading service:
import { ElLoading } from 'element-plus'
Invoke it:
ElLoading.service(options)
The parameter options
is the configuration of Loading, and its details can be found in the following table. LoadingService
returns a Loading instance, and you can close it by invoking its close
method:
const loadingInstance = ElLoading.service(options)
nextTick(() => {
// Loading should be closed asynchronously
loadingInstance.close()
})
Note that in this case the full screen Loading is singleton. If a new full screen Loading is invoked before an existing one is closed, the existing full screen Loading instance will be returned instead of actually creating another Loading instance:
const loadingInstance1 = ElLoading.service({ fullscreen: true })
const loadingInstance2 = ElLoading.service({ fullscreen: true })
console.log(loadingInstance1 === loadingInstance2) // true
Calling the close
method on any one of them can close this full screen Loading.
If Element Plus is imported entirely, a globally method $loading
will be registered to app.config.globalProperties
. You can invoke it like this: this.$loading(options)
, and it also returns a Loading instance.
