syntax error missing closing }

syntax error missing closing }

I get this error message:
SyntaxError: missing } after property list
right before the  ↵$('#taskform').

I checked all opening and closing () & {} in a syntax checker so i can't figure out where the missing } is?


------code--------
$(document).ready(function() {
    $.ajax({

          url: 'ajax/get_todosx3.php',
          dataType : 'json',
          success: function(data) {
        alert(success);
            var list_start ='<li "class" = "todo-list" >';
            var list_end ='</li>';
            var checkbx ='<input type="checkbox" id="task" checked="false" />';
            var delRow ='<input type="button" value="Delete" class="btnDelete"  onclick="deleteRow(this)" />';
                $('.result').html(data);
                alert('Load was performed.');
            var rows= ' ';
                $.each(data, function(idx,item) {
                    rows+= list_start + checkbx + item.todo + ', ' + item.name + item.date + delRow +list_end;
            });
            $("ul").append(rows);               
    }    //end success
        }) //end ajax   

 $('#taskForm').submit(function(e) {
        e.preventDefault();
        submitForm();
    });  //end document ready
