Passing Java Script Variable to a4j:commandButton

[richfaces76]

Hi,

I've a java script function which will return a variable and I need to pass that parameter to the a4j:commandButton action.I tried to pass the parameter as below but that parameter is not being retrieved in the backend bean.Any advise on this?

<script type="text/javascript">
                                     function onContributionWizardAfterAddEntry(entries) {                                   
                                    var uploadedEntry = entries[0].entryId;  
                                    }

</script>

<a4j:commandButton tabindex="1"
                                        image="../img/submit.gif"
                                        styleClass="uploadersubmit"   
                                        onmouseover="this.src='../img/submit_over.gif';" 
                                        onmouseout="this.src='../img/submit.gif';"
                                        action="#{objectivelistaction.uploadMediaEntry(uploadedEntry'}"                                       
                                        oncomplete="#{rich:component('uploadPanel')}.hide();disabled=true;"
                                        reRender="portfolioList"/>

Thanks,

Anil

something like:

<script type="text/javascript">
                                     function onContributionWizardAfterAddEntry(entries) {                                   
                                    var uploadedEntry = entries[0].entryId;  
                                    }

</script>

<a4j:commandButton tabindex="1"
                                        image="../img/submit.gif"
                                        styleClass="uploadersubmit"   
                                        onmouseover="this.src='../img/submit_over.gif';" 
                                        onmouseout="this.src='../img/submit.gif';"
                                        action="#{objectivelistaction.uploadMediaEntry(uploadedEntry'}"                                       
                                        oncomplete="#{rich:component('uploadPanel')}.hide();disabled=true;"
                                        reRender="portfolioList">

     <a4j:actionparam name="jsparam" escape="false" value="onContributionWizardAfterAddEntry(something)"

</a4j:commandButton>
