我收到以下错误

＆＃13;

Uncaught TypeError: Cannot use 'in' operator to search for 'length' in <!DOCTYPE html>

＆＃13;

我的代码的.each部分似乎失败了：

＆＃13;

        $.each(data, function(arrID, arrValue) {
          for(var d = resetUTC(arrValue.start_date); d<=resetUTC(arrValue.end_date); d.setDate(d.getDate()+1)){
            unavailableDates.push($.datepicker.formatDate('yy-m-d', d));
          }

＆＃13;

我尝试过很多东西，例如

＆＃13;

$.each(JSON.parse(data), function(arrID, arrValue) {

＆＃13;

＆＃13; 但最终得到了更多的错误：

＆＃13;

Uncaught SyntaxError: Unexpected token < in JSON at position 0
