aura:valueInit

Indicates that a value has been initialized. This event is triggered on app or component initialization.

This event is automatically fired when an app or component is initialized, prior to rendering. The aura:valueInit event is handled by a client-side controller. A component can have only one <aura:handler name="init"> tag to handle this event.

1<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>

For an example, see Invoking Actions on Component Initialization.

Setting value="{!this}" marks this as a value event. You should always use this setting for an init event.

Note

The init handler contains these required attributes.

Attribute Name	Type	Description
`name`	String	The name of the handler, which must be set to `init`.
`value`	Object	The value that is initialized, which must be set to `{!this}`.
`action`	Object	The client-side controller action that handles the value change.
