  • <apex:actionFunction>: A component that provides support for invoking controller action methods from Javascript code using an Ajax request.
    • An <apex:actionFunction> component must be child of an component.
  • <apex:actionStatus>: This Component i s used for displaying different values depending on whether it’s in progress or completed.
  • <apex:actionsupport>: A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover.
  • <apex:actionPoller>: This component specifies a timer that sends an Ajax update request to Force.com according to a time interval that we specify.
