i want to pass the following to the cfc but i am getting an error

FIELDNAMES TABLESLISTS[]
TABLESLISTS[] dbo.projects

old code is passing the value from ajax by declaring a array object and then push it to the call as {TABLESLISTS : TABLESLISTS} i wonder how to fix it

I wonder how you think anyone would be able to respond sensibly to this?

i do not know what you are expecting, so leave it if not understood Thanks

Well, maybe tell us what the error actually is would be a good start

Yes, Here is how it is happening

var tablesLists = [];
    $("select").each(function(){ 
        var id = $(this).attr("id");
        var value = $(this).val();
        if ( id == 'fromModel' && value != null) {
            var value = $(this).val();
            if ( value.length > 0 ) {
                tablesLists.push ( $(this).val() );
            }
        }
    });

    fields = [];
    console.log( "tables lists ->" + tablesLists)
    if ( tablesLists.length > 0 ) {
    $.ajax({ 
        type: 'POST',
        url: "/myrcfc.cfm?object=fields",
        data: JSON.stringify(tablesLists),
        dataType: "json",
        success: function(parsedData){ 

		var response = JSON.parse(parsedData);
    }
    });
    }

the above JS code is sending the form data as i stated above in my first post of question

OK. So that is posting to a .cfm file not a .cfc as you mentioned originally.

ok, let me try that

no,

join

converts an javascript array to a string. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/join
