问题描述
我得到这个错误时,我送2参数从jQuery来的WebMethod,并使用多个PARAMS。
I got this error when i send 2 parameter from jQuery to WebMethod and using multiple params.
{"Message":"Invalid web service call, missing value for parameter: \u0027haha\u0027.","StackTrace":" at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
在jQuery的:
$(".txtNoiDung").focusout(function () {
$.ajax({
type: "POST",
url: "QuanLyTin.aspx/test1cai",
data: JSON.stringify({ hahas: $(this).val(),tuans: "hahaha" }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
$("#vltxtNoiDung").text(msg.d)
},
error: function (xhr, reason, ex) {
alert(reason);
}
});
});
在code后面
[WebMethod()]
public static string test1cai(string haha, string tuan)
{
return "Hi, "+haha + tuan;
}
我该如何解决呢?
谢谢你们。
How can i resolve it?Thanks you guys.
推荐答案
您服务正在接受命名参数哈哈
和疃
,但你的JavaScript在 hahas 和
tuans
。从两个删除的S:
Your service is accepting parameters named
haha
and tuan
, but your JavaScript is passing in hahas
and tuans
. Remove the "s" from both:
data: JSON.stringify({ haha: $(this).val(),tuan: "hahaha" }),
另外,请记住,这些参数区分大小写客户端和服务器端的之间没有太大的匹配的
