将jQuery数组转换为字符串

Question

$('#btnAfterExtraServicesSelected').die('click').live('click', function () {

   var keys = $('#extras input:checked').map(function () { return $(this).val(); }).get();
   var pets = $('#pets input:checked').map(function () { return $(this).val(); }).get();
   var selectedExtraServices = {};

     for (var i = 0, l = pets.length; i < l; i++) {
         if (pets[i]) {
            var selectedPetKeys = [];
            var name = pets[i] + '-';
            for (var j = 0, k = keys.length; j < k; j++) {
                if (keys[j].substring(0, name.length) == name) {
                     selectedPetKeys.push(keys[j].substr(name.length));
                  }
            }
   selectedExtraServices['extras-' + pets[i]] = (selectedPetKeys.join('+') || '-');
   selectedExtraServices['rextras-' + pets[i]] = null;
                        }
                    }

$('#available-rooms').load('/PetBooking/GetAvailableRoomsForTimesAndDates/', {'selectedExtraServices': selectedExtraServices }, function () {

                    });

                    return false;
                });

我需要将＆＃34; selectedExtraServices＆＃34; 数组作为字符串传递给＆＃34; load（）＆＃34; 方法。我怎么能实现那个？

selectedExtraServices jQuery对象如下：

Answer 1

尝试

$('#available-rooms').load('/PetBooking/GetAvailableRoomsForTimesAndDates/', {'selectedExtraServices': JSON.stringify(selectedExtraServices) }, function () {

});

Answer 2

为什么不使用JSON.stringify？

{'selectedExtraServices': JSON.stringify(selectedExtraServices )}
