推荐答案

您的测试方法需要 static

Your Test method needs to be static

[System.Web.Services.WebMethod]
 public static string Test()
 {
     return "hello";
 }

function runTest() {
        PageMethods.Test(OnSucceeded, OnFailed);
    }

    function OnSucceeded(response) {

        alert(response);
    }
    function OnFailed(error) {
        alert(error);
    }

[System.Web.Services.WebMethod]
       public static string Test()
       {
           return "hello";
       }
