coldfusion ajax json data return data not in proper format

Question

I am trying to return an array of struct through ajax to provide autocomplete feature. I am trying to call getEmployeeName through ajax from the page where i want to populate the textbox.

The test.cfc is as follows:

<cfcomponent>
<cffunction name="getEmployeeName" access="remote" returnformat="JSON" >
    <cfargument name="term" type="string" required="yes">

    <cfset var returnArray=ArrayNew(1) />
    <cfset term=#Ucase(term)#>
    <cfquery name="getEmps" datasource="mines">
        ...
        <!--- my query ---!>
    </cfquery>

    <cfoutput>
    <cfloop query="getEmps">
        <cfset empStruct = StructNew() />
        <cfset empStruct["label"] = #emp_name# & " " &#desg_desc# & " " & #unit_name# />
        <cfset empStruct["value"] = #cpf_no#>

        <cfset ArrayAppend(returnArray,empStruct) />
    </cfloop>
    </cfoutput>
    <cfreturn #serializeJSON(returnArray)#>
</cffunction>

The ajax call is as follows:

$("#task_coordinator").autocomplete({
            source: function (request, response) {
                     $.ajax({
                             url: "test.cfc?method=getEmployeeName",
                             type: "GET",
                             data: request,
                             success: function (data) {



                                    console.log(data);
                                    console.log(data.array([label]));

                             },
                             error: function(jqXHR, extStatus,errorThrown){
                                alert(errorThrown);
                             }
                     });
            },
            select: function (event, ui) {

            }
            ,minLength:5
    });

I have tried calling the method directly through the link to see whether it is working fine or not. At that it is returning only json data and not this extra information. My output has extra script before json data:

        _CF_error_fields = new Object();
        _CF_FirstErrorField = null;


        //display error messages and return success
        if( _CF_error_exists )

                // set focus to first form error, if the field supports js focus().
                if( _CF_this[_CF_FirstErrorField].type == "text" )
                { _CF_this[_CF_FirstErrorField].focus(); }

            }
            return false;
        }else {
            return true;
        }
    }
//-->
</script>
[{"value":47455,"label":"BANTHIA ANUJA RAVINDRAKUMAR GRADUATE EXECUTIVE TRAINEE(E2) CENTRAL ESTABLISHMENT"}]   

Can somebody tell me why this extra script is coming. Thanks in advance!

In your ColdFusion Administrator, select Debugging & Logging > Debugger Settings. You should find some settings in there to help debug AJAX requests. Try turning that off if it's checked.

Here's some info that might help. http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec10e40-8000.html
