Action Methods

Action methods perform logic or navigation when a page event occurs, such as when a user clicks a button, or hovers over an area of the page. Action methods can be called from page markup by using {! } notation in the action parameter of one of the following tags:

• <apex:commandButton> creates a button that calls an action
• <apex:commandLink> creates a link that calls an action
• <apex:actionPoller> periodically calls an action
• <apex:actionSupport> makes an event (such as “onclick”, “onmouseover”, and so on) on another, named component, call an action
• <apex:actionFunction> defines a new JavaScript function that calls an action
• <apex:page> calls an action when the page is loaded
