CommandButton onClick() action problem

Question

Hi every one ,
I want to execute an Ajax function when clicking on submit button before submitting the page like this :
<h:commandButton value="Go" onclick="myFun();" action="#{myController.getPropertyName}"/>where this javascript function will show a yes/no message then an Ajax function will be executed according to the user choice.
The problem is that the j.s function is not even executed but the action is submitted directly.
And from what i understood is that JSF reserves onclick() function to execute "action" property, that's why it can't feel the onclick() i wrote.
I also tried using onmousedown() instead but still the action is submitted directly.
Any suggestions ?

Yes, i thought so but i can't change the JSF version used in the project, so is there a way to overcome this ?Perhaps one of the other events fired by the button will be sufficient (e.g., onmouseup). You could also try to implement your own component for this.
