[英]Passing JSON to a Controller with Multiple Models and/or Parameters via AJAX POST
我寫了這個控制器:
[HttpPost]
public JsonResult CheckOut(List<POS_model> pos, double totalPayment)
{
try
{
var json = JsonConvert.SerializeObject(pos);
DataTable posTable = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));
posTable.Columns["discount_percent"].ColumnName = @"Discount %";
POS m_pos = new POS();
m_pos.Data = posTable;
m_pos.totalPayment = totalPayment;
m_pos.CheckOut();
return Json(new
{
Status = "Success"
});
}
catch
{
return Json(new
{
Status = "Fail"
});
}
}
我嘗試編寫此AJAX腳本來調用參數並將其提交給Controller :(但不起作用)
var totalPay = 1000;
var GatherPosItems = $('#tblPOS').tableToJSON();
$.ajax({
type: 'POST',
data: JSON.stringify(GatherPosItems)+"&totalPayment="+totalPay,
url: '@Url.Action("CheckOut", "POS")',
dataType: "json",
contentType: 'application/json; charset=utf-8',
success: function (data) {
alert('Success');
},
error: function (req, status, errorObj) {
alert(errorObj.toString());
}
});
GatherPosItems
是帶有多個“行”或對象的JSON,因此它是一個數組。
我添加了一個參數totalPayment
。
如何將GatherPosItems
和totalPayment
都totalPayment
給控制器?
我的模特:
public class POS_model
{
public string Qty { get; set; }
public string description { get; set; }
public string price { get; set; }
public string discount_percent { get; set; }
public string Discount_amount { get; set; }
public string Discounted_price { get; set; }
public string Line_total { get; set; }
public string is_vat { get; set; }
public string track_type { get; set; }
public string item_line_id { get; set; }
public string id { get; set; }
public string sale_code { get; set; }
public string reference { get; set; }
public string unit_of_measure { get; set; }
public string location { get; set; }
public string item_code { get; set; }
}
我的GatherPosItems
的結果:
您將非JSON字符串( &totalPayment="+totalPay
)連接到從JSON.stringify
函數返回的JSON,這將破壞發送到服務器的數據格式,並使模型綁定程序無法解析它。
以下應該工作:
$.ajax({
type: 'POST',
data: JSON.stringify({pos: GatherPosItems, totalPayment: totalPay}),
url: '@Url.Action("CheckOut", "POS")',
dataType: "json",
contentType: 'application/json; charset=utf-8',
success: function(data) {
alert('Success');
},
error: function(req, status, errorObj) {
alert(errorObj.toString());
}
});
