[jQuery] Help Creating An Array

I've got a table that is produced through 2 loops (using coldfusion).
I need to be able to place the classes within an array, that way I can
calculate the columns and rows. Here is the link:

The JavaScript looks like:

                           $('.calc').change(function(){
                                var classArray = new 
Array("'"+$(this).attr("class").replace(/ /
g,"','")+"'");
                                alert(classArray.length);

                                $.each(classArray, function(){
                                        //alert(this);
                                        });
                            });


Loops creating the table, with the inputs and classes.

                        <cfloop from="1" to="#ArrayLen(labels)#" index="r">
                        <tr>
                                <td class="labels"><cfif 
ArrayIsDefined(labels,r) AND labels[r]
NEQ "Open">#labels[r]#</cfif></td>
                                <cfloop from="1" to="7" index="i">
                                <td id="Day#i#" class="row#r# col#i#">
                                        <cfif r EQ 
1>#Left(DayOfWeekAsString(i),3)#<cfelse><cfif r EQ
2><input type="text" class="date-mask" /><cfelse><input type="text"
class="calc R#r# C#i#" /></cfif></cfif></td>
                                </cfloop>
                                <td class="totals"><cfif r EQ 
1>Total<cfelse><input type="text"
class="ttl#r# vttl#i#" readonly="readonly" /></cfif></td>
                        </tr>
                        </cfloop>
