how to get selected value of p:column of p:dataTable

Question

I want to get selected value of p:column of p:datatable by using javascript(jquery). Do you think is that possible ? I tried several ways but I could not succeed. Any help will be great.

Regards

Here is the sample Code :

<p:dataTable id="attachmentsTable" var="dataRow" value="#{taslakFaturaBean.attachments}" style="width:980px; text-align:center;">
            <p:column headerText="ID">
                #{dataRow.AttachID}
            </p:column>
            <p:column headerText="Dosya Tarihi">
                #{dataRow.AttachDate}
            </p:column>
           <p:column headerText="Dosya">
                <p:commandButton id="downloadLink" value="İndir" icon="ui-icon-arrowthichk-s" rendered="#{not empty dataRow.AttachData}" ajax="false">
                </p:commandButton>
            </p:column>

I want to get selected p:column's AttachId when I click downloadLink commondButton by javascript.

If you want pure javascript I think it can be by this way

<script type="text/javascript">
        function test(attachId) {
            // get attachId
        }
</script>

and in your dataTable like this

<input type="button" onlcick="test(#{dataRow.AttachID});" value="GetID" />

if you want to use commandButton you can try to use onclick="test(#{dataRow.AttachID})" but not sure about that :)
