Use Ajax in a Page
Some Visualforce components are Ajax aware. With these components,
you can add Ajax behaviors to a page without writing any
JavaScript.
-
Implement Partial Page Updates with Command Links and Buttons
One of the most widely used Ajax behaviors is a partial page update, in which only a specific portion of a page updates following some user action, rather than a reload of the entire page. The simplest way to implement a partial page update is to use the reRender attribute on an <apex:commandLink> or <apex:commandButton> tag. When a user clicks the button or link, only the identified component and all of its child components refresh. -
Provide Status for Asynchronous Operations
Ajax behaviors, such as partial page updates, are asynchronous events that occur in the background while a user continues to work. With the <apex:actionStatus> component, you can display status messages that alert the user of any background activity currently in progress. -
Apply Ajax Behavior to Events on Any Component
Implement a partial page update without using command links or buttons. For example, a user can hover over a component to trigger the update.
