在 AJAX 调用时将对象发送到 WebMethod
本文关键字:WebMethod 对象 AJAX 调用 | 更新日期: 2023-09-27 17:56:00
我正在尝试将JSON对象发送到C#方法,并返回另一个(也是JSON)对象。
该对象是在 JavaScript 中创建的:
lottery = {
TotalValue: totalValue,
Players: txtPlayers.value,
TicketPrice: txtAmount.value,
FirstPrize: prize,
MyComission: myComission,
MyRate: myRate,
SellerComission: sellerComission,
SellerRate: sellerRate
}
然后通过 AJAX 发送:
function CreateLottery(lottery) {
$.ajax({
type: 'POST',
url: 'default.aspx/Create',
data: lottery,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (data, status) {
alert(status)
},
error: alert("error!")
});
}
C# 代码隐藏(我有断点,它永远不会到达这里):
[WebMethod]
public static object Create(Lottery lottery)
{
return new
{
foo = "bar",
};
}
public class Lottery
{
public decimal TotalValue { get; set; }
public decimal Players { get; set; }
public decimal TicketPrice { get; set; }
public decimal FirstPrize { get; set; }
public decimal MyComission { get; set; }
public decimal MyRate { get; set; }
public decimal SellerComission { get; set; }
public decimal SellerRate { get; set; }
}
为什么我总是收到"错误!"警报?
您可以将数据发送到Web方法,下面给出了两种类型的方法。
方法 1
您可以在 web 方法中传递每个属性值,例如
function CreateLottery(lottery) {
$.ajax({
type: 'POST',
url: 'default.aspx/Create',
data: {'TotalValue': totalValue, 'Players': txtPlayers.value,'TicketPrice': txtAmount.value, 'FirstPrize': prize, 'MyComission': myComission, 'MyRate': myRate, 'SellerComission': sellerComission, 'SellerRate': sellerRate},
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (data, status) {
alert(status)
},
error: alert("error!")
});
}
方法 2
使用 JSON.stringify(lottery)
将数组对象更改为字符串。
var lottery = {
TotalValue: totalValue,
Players: txtPlayers.value,
TicketPrice: txtAmount.value,
FirstPrize: prize,
MyComission: myComission,
MyRate: myRate,
SellerComission: sellerComission,
SellerRate: sellerRate
}
function CreateLottery(lottery) {
$.ajax({
type: 'POST',
url: 'default.aspx/Create',
data: JSON.stringify(lottery),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (data, status) {
alert(status)
},
error: alert("error!")
});
}
首先字符串化数据:
var lottery = {
TotalValue: totalValue,
Players: txtPlayers.value,
TicketPrice: txtAmount.value,
FirstPrize: prize,
MyComission: myComission,
MyRate: myRate,
SellerComission: sellerComission,
SellerRate: sellerRate
}
function CreateLottery(lottery) {
$.ajax({
type: 'POST',
url: 'default.aspx/Create',
data: JSON.stringify(lottery),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (data, status) {
alert(status);
},
error: function () {
alert("error!");
}
});
}
编辑:您的错误回调定义不正确,每次进行 ajax 调用时都会触发。修改如上所示。
