[ACCEPTED]-Execute managebean method from javascript onload event-jsf-2
In theory the following should do it.
<h:body>
<f:ajax event="load" listener="#{bean.onload}" />
</h:body>
with
public void onload(AjaxBehaviourEvent event) {
// ...
}
However, this 8 is not supported for some reason. I've ever 7 posted an issue report about that.
The following works, but 6 it's in essence a hack.
<h:head>
<title>JSF 2.0 onload hack</title>
<script>
window.onload = function() {
document.getElementById('hidden:link').onclick();
}
</script>
</h:head>
<h:body>
<h:form id="hidden" style="display:none">
<h:commandLink id="link">
<f:ajax event="click" listener="#{bean.onload}" />
</h:commandLink>
</h:form>
</h:body>
If you happen to 5 use PrimeFaces, then you can use its <p:remoteCommand> with 4 autoRun set to true.
<h:body>
<h:form>
<p:remoteCommand name="onload" action="#{bean.onload}" autoRun="true" />
</h:form>
</h:body>
Or if you're using OmniFaces, then you 3 can use its <o:commandScript>
<h:body>
<h:form>
<o:commandScript name="onload" action="#{bean.onload}" />
<h:outputScript target="body">onload()</h:outputScript>
</h:form>
</h:body>
The <h:outputScript target="body"> renders the <script> in the end 2 of the <body>. The upcoming OmniFaces 2.2 will 1 remove this need by new autorun attribute.
<h:body>
<h:form>
<o:commandScript name="onload" action="#{bean.onload}" autorun="true" />
</h:form>
</h:body>
in jsf2.0 you can use the f:ajax tag in 4 almost any other jsf tag e.g
<h:selectOneRadio id="myComponent" value="#{someBean.inputMethod}">
<f:selectItem itemValue="#{someBean.A}" itemLabel="A" />
<f:selectItem itemValue="#{someBean.B}" itemLabel="B" />
<f:ajax event="click" action=#{someBean.someMethod} />
</h:selectOneRadio>
In this example 3 the someMethod is excuted in the javasript 2 onClick event for the "myComponent" selectOneRadio
Not 1 sure if this is what you are after ....
