Hello friend

The given below code validates the input field (checks that it has a value entered) before the form is submitted :

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

<f:view>
<script type="text/javascript">
function valid(form)
{

var Value = form["FormName:name"].value;
if (Value == "")
{
alert("Please enter Subject");
form["FormName:name"].focus();
return false;
}
form.submit();
return true;
}
</script>
<h:form id="FormName">

<h:outputText styleClass="jsf-output-text" value="Enter your name"/>
<h:panelGroup>
<h:inputText styleClass="jsf-output-text" id="name" value="#

{BeanName.attribute}" required="true"/>
<h:commandButton value="Submit" type="submit" styleClass="jsf-command-button"

action="#{BeanName.function}" onclick="return valid(this.form);"/>
</h:panelGroup>

</h:form>
