You can use both apex/vf tags and HTML tags. It depends on the scenarios. I have written one small example to explain both scenarios.
If you use the HTML tags then you have to write Javascript functions to call apex methods like in below example ( Scenario 1 ).
Scenario 1. Using HTML tags:
1. HTML <script type="text/javascript"> jQuery(document).ready(function(){ jQuery('.btn').click(function(){ callTestMethod(); }); }); </script> <apex:page> <apex:actionfunction name="callTestMethod" action="{!testMethod}" /> <input type="button" value="Test" Class="btn"/> </apex:page>If you use VF tags then you can directly call apex methods through action attribute ( scenario 2 ).
Scenario 2: Using Apex/VF tags:
<apex:page controller="testClass"> <apex:form> <apex:commandButton styleClass="btn " value="test" action="{!testMethod}"/> </apex:form> </apex:page>Apex Class:
Public class testClass{ public PageReference testMethod(){ PageReference retVal = page.TestPage; retVal.setRedirect(true); return retVal; } }For the VF performance and best practices please refer to the following links:
