ASP.NET jQuery error: Unknown Web Method
提问by Mark Struzinski
This is my first time attempting to call an ASP.NET page method from jQuery. I am getting a status 500 error with the responseText message that the web method cannot be found. Here is my jQuery $.ajax call:
这是我第一次尝试从 jQuery 调用 ASP.NET 页面方法。我收到一个状态 500 错误，带有无法找到 Web 方法的 responseText 消息。这是我的 jQuery $.ajax 调用：
function callCancelPlan(activePlanId, ntLogin) {
var paramList = '{"activePlanId":"' + activePlanId + '","ntLogin":"' + ntLogin + '"}';
$.ajax({
type: "POST",
url: "ArpWorkItem.aspx/CancelPlan",
data: paramList,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function() {
alert("success");
},
error: function(xml,textStatus,errorThrown) {
alert(xml.status + "||" + xml.responseText);
}
});
}
And here is the page method I am trying to call:
这是我试图调用的页面方法：
[WebMethod()]
private static void CancelPlan(int activePlanId, string ntLogin)
{
StrategyRetrievalPresenter presenter = new StrategyRetrievalPresenter();
presenter.CancelExistingPlan(offer, ntLogin);
}
I have tried this by decorating the Web Method with and without the parens'()'. Anyone have an idea?
我已经通过使用和不使用括号'()'来装饰 Web 方法来尝试这个。有人有想法吗？

Clean the solution and rebuild. I've seen webmethods throw 500's until you do this.
清洁溶液并重建。我已经看到 webmethods 抛出 500 直到你这样做。
