[jQuery] Return data from dimensions.js

[jQuery] Return data from dimensions.js


I need to save the coordinates of a div to be able to return it to the
same location and am having problems posting the offset from
dimensions.js
This
$(".dragL").mouseup(function(e){
        var stroke = $(this).attr("id");
        var coordsB = $(this).offset({ scroll: false });
        $.post("pre_scripts.cfm", {
        coords: e.pageX +','+ e.pageY,
        coordsDiv: coordsB,
        strokeNo: stroke
        },
        function(data){
         //alert(data);
         var commaAt = data.indexOf(',');
             $( '#' + data.substr(0, commaAt) ).text( data.substr(commaAt
+1) );
        });
    });
posts this
COORDSDIV: [object Object]
STROKENO: S2
COORDS: 122,129
How do I read [object Object]
