 We have two types of action given below:
  • Remote Action- JavaScript in VF page call server from Button.
  • Action tags-This tags support for calling action and refresh the field only not visualforce page.
Given below are the different action tags:

  1. apex:actionFunction-
    Provides support for invoking controller action methods directly from JavaScript code using an AJAX request. An <apex:actionFunction> component must be a child of an <apex:form> component.

  1. apex:actionPoller
     A timer that sends an AJAX update request to the server according to a time interval that you specify. Update request can then result in a full or partial page update. You should avoid using this component with enhanced lists.

  1. apex:actionRegion
       This action tag is use AJAX request for particular field or component. Like we have change the value of pick list in visual force then request go to Server and come back through AJAX without Saving the VF page.

  1. apex:actionStatus
          A component that displays the status of an AJAX update request. An AJAX request can either be in progress or complete

  1. apex:actionSupport
     Adds AJAX support to another component, allowing the component to be refreshed asynchronously by server when a particular event occurs, such as a button click or mouse over.
