# Converting CFML Data to a JavaScript Object

The following example demonstrates the transfer of a CFQUERY result set from a CFML template executing on the server to a JavaScript object that is processed by the browser.

The application consists of five principal sections:

- Running a data query
- Including the WDDX JavaScript utility classes
- Specifying the conversion type and the input and output variables
- Calling the conversion function
- Outputting the object data in HTML

This example uses a registered ColdFusion datasource and can be run from ColdFusion Server.

    <!--- Create a simple query  --->
    <CFQUERY NAME = 'q' DATASOURCE ='snippets'>
        SELECT Message_Id, Thread_id,
        Username, Posted from messages
    </CFQUERY>

    <!--- Cache the JavaScript so that subsequent requests will --->
    <!--- use the cached version rather than making additional --->
    <!--- requests to the server --->

    <SCRIPT LANGUAGE="JavaScript"
        SRC="/CFIDE/scripts/wddx.js"></SCRIPT>

    <!--- Bring in WDDX JS support objects
         A <SCRIPT SRC=></SCRIPT> can be used instead
         wddx.js is part of the ColdFusion distribution --->
        <CFINCLUDE TEMPLATE='/CFIDE/scripts/wddx.js'>

        <!--- Use WDDX to move from CFML data to JS --->
        <CFWDDX ACTION='cfml2js' input=#q# topLevelVariable='q'>

        <!--- Dump the recordset --->
        q.dump(true);

    </SCRIPT>
