Question

我正在使用JSON stringify转换复杂对象。

我想要这种输出，以便可以轻松地将其与模型绑定。

DateRequired: "2019-02-02"
DeliveryDestination: "test"
ProjectCode: "002P"
RequestItems: {InventoryItemsId: "2", Brand: "NIKE", Types: "Casual", Specification: "Mentality", ItemName: "Wild"},
{InventoryItemsId: "3", Brand: "PUMA", Types: "Running", Specification: "Energy", ItemName: "Wild"}

但是我得到了这个。

DateRequired: "2019-02-02"
DeliveryDestination: "test"
ProjectCode: "002P"
RequestItems: Array(2)
0: {InventoryItemsId: "2", Brand: "NIKE", Types: "Casual", Specification: "Mentality", ItemName: "Wild", …}
1: {InventoryItemsId: "3", Brand: "PUMA", Types: "Running", Specification: "Energy", ItemName: "Wild", …}
length: 2
__proto__: Array(0)
__proto__: Object

这是发布数据的代码：

var items = postAllItems(); //this is an array
                var materialRequest = {
                    'DateRequired': $('#txtDateRequired').val(),
                    'ProjectCode': $('#txtProjectCode').val(),
                    'DeliveryDestination': $('#txtDeliveryDestination').val(),
                    'RequestItems': items
            };

 postMaterialRequest(materialRequest);

function postMaterialRequest(materials) {
            $.ajax({
                contentType: 'application/json',
                type: 'POST',
                url: '/api/PostMaterial',
                data: JSON.stringify(materials),
                success: function (data) {
                    console.log("Info Save " + data);                   
                },
                failure: function (response) {
                    console.log('Failed to save.');
                }
            });
        }

这就是我从Web API所获得的

是正确的输出-这只是控制台显示对象的方式。使用StackOverflow的控制台或使用JSON.stringify，可以显示所需的输出：

var myObj = {
  DateRequired: "2019-02-02",
  DeliveryDestination: "test",
  ProjectCode: "002P",
  RequestItems: [{
      InventoryItemsId: "2",
      Brand: "NIKE",
      Types: "Casual",
      Specification: "Mentality",
      ItemName: "Wild"
    },
    {
      InventoryItemsId: "3",
      Brand: "PUMA",
      Types: "Running",
      Specification: "Energy",
      ItemName: "Wild"
    }
  ]
};

console.log(myObj);
console.log(JSON.stringify(myObj));

.as-console-wrapper { max-height: 100% !important; top: 0; }

我通过使用下面的代码解决了我的问题，我的问题全部是关于不将同步与异步功能混合在一起。其中ajax发布首先完成。我用setTimeout来延迟ajax发布。感谢@trincot链接。

function createObject() {
            var mr = { DateRequired: $('#txtDateRequired').val(), ProjectCode: $('#txtProjectCode').val(), DeliveryDestination: $('#txtDeliveryDestination').val(), RequestItems: [] };
            for (var i = 0; i < insMaterials.length; i++) {
                var mtr = insMaterials[i];
                alert(mtr);
                var RequestItems = {
                    'InventoryItemsId': mtr.InventoryItemsId,
                    'Brand': mtr.Brand,
                    'ItemName': mtr.ItemName,
                    'Quantity': mtr.qty,
                    'RefNo': 3,
                    'Comment': mtr.remarks,
                    'Specification': mtr.specification,
                    'Types': mtr.types,
                    'Unit': mtr.qty
                };
                mr.RequestItems.push(RequestItems);
            }
            return JSON.stringify(mr);
        }


function postMaterialRequest() {
            $.ajax({
                contentType: 'application/json',
                async: false,
                type: 'POST',
                url: '/api/PostMaterial',
                data: (createObject()),
                success: function (data) {
                    console.log("Info Save " + data);
                    toastr.success('Request was submitted successfully!');
                    del();
                },
                failure: function (response) {
                    console.log('Failed to save.');
                    toastr.error('Failed to save.');
                }
            });
        }


postAllItems();
setTimeout(postMaterialRequest, 3000);

JSON.stringify的单行输出
