onSuccess 和 onFailure 不会被触发

onSuccess and onFailure doesn't get fired

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

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,它起作用了:

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?

您的 PageMethod 看起来像这样

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

当你调用它时,它看起来像这样

PageMethods.LoginUser(email, pass);

您的参数应该与方法的顺序相同。

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