onSuccess和onFailure不会被解雇

Question

我在PageMethod调用中使用了onSuccess和onFailure。然而，它们都没有被调用，WebMethod也没有被解雇。

alert("1");
PageMethods.LoginUser(onSuccess, onFailure, email, pass);
alert("2");

function onSuccess(val)
{
}
function onFailure()
{
}

[WebMethod(EnableSession = true)]
public static int LoginUser(string email, string pass)
{
       //Doesn't get fired
}

当我删除它们并仅将值发送到WebMethod时，它可以工作：

PageMethods.LoginUser(email, pass);
//This fires the Web Method

我也在我的ScriptManager中启用了PageMethods。我做错了什么？

Answer 1

你PageMethod看起来像这样

PageMethods.LoginUser(onSuccess, onFailure, email, pass);

当你打电话时，它看起来像这样

PageMethods.LoginUser(email, pass);

您的参数应与方法的顺序相同。

PageMethods.LoginUser(email, pass, onSuccess, onFailure);
