How to use the js variable in cfquery

This is the js Function , I need to use the "DataFileImportID" variable inside the Cfquery.

What I have tried:

<pre>    <script language="Javascript" type="text/javascript">
    function Validate(DataFileImportID)
     {
        var DataFileImportID=DataFileImportID;
         alert(DataFileImportID);
        <CFQUERY name="get" DATASOURCE="HeliosMaster">
            select top 1  Description 
            from CDSDB01.dbo.BenchmarkReject  
            WHERE   Filemasterid ='#DataFileImportID#' and Description='Invoice totals do not 
 match loaded charge totals'
        </cfquery>
        alert("tets1");
        alert(get.recordCount);
        return confirm ("test");
     } 
    </script>
</cfoutput>
