If you understand Javascript, then you should know that "return false;" after the event will prohibit the form being submitted.This has nothing to do with JSF tho, but just with basic HTML/JS knowledge.

There are also a few projects that make JSF validation both server and client side. Off the top of my head, there's MyFaces Trinidad, Shale, and I think there was something in the MyFaces Tomahawk Sandbox.Google for JSF client side validation.

HI Balu,

I can understand JavaScript. but the problem is see the following code :

<h:commandButton onclick="validate('val')" value="Next" action="#{ld90Bean.next}"/>

onclick event i am calling the validate method todo validations. but even the validation fails its submiting.

You've got to return false from the onlick if you don't want the button to submit.

<h:commandButton onclick="return validate('val')" ... />

validate(val) {

... do validation ...

if (validates) {

return true;

} else {

return false;

}
