Ajax in Visualforce page
In Visualforce, you can use Ajax (Asynchronous JavaScript and XML) techniques to perform asynchronous requests to the server without refreshing the entire page. This allows you to update specific parts of the page dynamically, providing a smoother and more responsive user experience. Here's how you can use Ajax in Visualforce pages: Using <apex:actionFunction>: <apex:actionFunction> allows you to define a JavaScript function that invokes an Apex controller method without a full page refresh. It's typically used to perform server-side actions based on user interactions. Example <apex:page controller="MyController"> <apex:form> <apex:commandButton value="Click Me" onclick="doAction(); return false;"/> <apex:actionFunction name="doAction" action="{!myControllerMethod}" rerender="outputPanel"/> </apex:form> <apex:outputPanel id="outputPanel"...
