问题描述
这是我第一次尝试使用Ajax将数据发送到服务器.我从这里得到了很多答案,但我不会只是停止获取错误:"Message":"Invalid web service call, missing value for parameter: \u0027Products\u0027."
This is first time I am attempting to send data to server using Ajax. I followed lot of answers from here but I won't just stop getting the error : "Message":"Invalid web service call, missing value for parameter: \u0027Products\u0027."
I followed this and this but still the same. Can someone please tell me where I am going wrong.
var products = [ { ProductId : 1, ProductName : "Mercedes", Category : "Cars", Price : 25000 }, { ProductId : 2, ProductName : "Otobi", Category : "Furniture", Price : 20000 } ];
function GetProductId() {
$.ajax({
type: "POST",
url: "Default.aspx/GenerateQrCode",
data: { "Products" : products.toString() },
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(xhr.responseText);
alert(thrownError);
},
success: function (msg) {
alert('Success');
}
});
}
[WebMethod]
public static void GenerateQrCode(object Products)
{
//Cannot get to here
}
推荐答案
尝试一下-
data : "{'Products':" + JSON.stringify(products) + "}"
