I am trying to make call to JSF functions in my app more dynamic. Instead of static way of writing callback functions to oncomplete event by hand, I wish to send a callback function as a parameter and make it's invoke inside oncomplete event of the function. Here's an example:

<script type="text/javascript">

     myFunc('myParamValue', function(){

          doThis();

          andDoThis();

     });

</script>

 

<a4j:jsFunction name="myFunc" actionListener="#{...}" data="" oncomplete="">

     <f:param name="myParam" />

     <f:param name="callback" />

</a4j:jsFunction>

I wish to ask if that would be possible by using data attribute of a4j:jsFunction? Something like this:

...

data="#{myBean.callback}"

oncomplete="if (typeof window[event.data] == 'function') window[event.data]();"

...
