Working with JavaScript & CSS

        

JSF provides so many attributes to provide javascript support like onblur, onchange, onclick, ondblclick, onfocus, onkeydown, onkeypress, onkeyup, onmousedown, onmouseover, onmouseup, onselect etc. For using CSS, JSF provides style and styleClass attributes for the components. You can use this as in the example below:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<f:view>
<html>
<head>
<title>JSF JavaScript & CSS</title>
<script type="text/javascript">
function checkName(){
  var name = document.getElementById("myform:name").value; 
  if(name.length<1){
  alert("Name can not be blank.");
  return false;
  }
  if(name.length>4){
  alert("Name can not be more than 4 characters.");
  return false;
   }
}
</script>


<style type="text/css">
   .inputbox {
   background-color:#FFFFFF; 
   color: #333333;
   width:200px;
   border-width:1px;
   border-style:solid;
   border-color:#808080;
  }
  .submitbutton{
   background-color:#367BB7;
   border:1px solid #2E76B4;
   color: #ffffff;
   text-align: center;
   width: auto;
   padding: 2px 3px 2px 3px;
   } 
</style>


</head>

<body>
<h:form id="myform"> 
<h:outputText value="Enter your Name: " style="font-weight:bold;"/>
<h:inputText id="name" styleClass="inputbox"/>

<br><br> 
<h:commandButton onclick="return checkName()" styleClass="submitbutton" action="test" value="Submit" /> 
</h:form>
</body>
</html>
</f:view>
