How to send JSF Expression Language value as paramter to javascript function

[Corey Harden]

Hi,
When an input field is focused on, I'm trying to call a javascript function with the parameter for the function being a JSF Expression Language value.
I know that this is allowed in regular JSP's where you pass a java variable to a function like so: onFocus="someFunction(<%= var %>)
So my question is what is the equivalent of this expression in ADF Faces using expression language (EL). This is the code that I have tried
in the onFocus attribute:

                    <af:inputText value="#{row[item.inputTxt]}" 
                                columns="#{item.colWidth}"
                                maximumLength="#{item.colWidth}"
                                disabled="#{item.disable || row["status"] == "L"}"
                                onblur="this.value=this.value.toUpperCase();"
                                styleClass="#{row.rowKeyStr==bindings.findAllVPlisnPlpartsByPccnId1.currentRowKeyString ? 'selectedRow' : ''}"
                                onfocus="#{setRowIndex(row.rowKeyStr)}"/>
                            </af:column>   

Thanks in advance for your help!
