按照描述Here

点击后，我将禁用该按钮

这是我的代码，但点击后无法禁用该按钮。

<h:head>
    <title></title>

    <script language="JavaScript" type="javascript">
        function handleDisableButton(data) {
            if (data.source.type != "submit") {
                return;
            }

            switch (data.status) {
                case "begin":
                    data.source.disabled = true;
                    break;
                case "complete":
                    data.source.disabled = false;
                    break;
            }
        }

        jsf.ajax.addOnEvent(handleDisableButton);
    </script>

</h:head>
<h:body>

    <h:form>
        <h:inputText id="email" value="#{bean2.email}"/>

        <h:commandButton id="saveBtn" action="#{bean2.showClicked}" value="send">
            <f:ajax onevent="handleDisableButton"/>
        </h:commandButton>

    </h:form>
</h:body>
</html>

而showClicked()只是说clicked：

@ManagedBean
@SessionScoped
public class Bean2 {

private String email;

public void showClicked(){
    System.out.println("clicked");
}
//getter/setter for email
}

代码正是他的首选。
