Question

我制作了一个简单的示例Web项目（使用vs 2015 Empty模板），其中包含一个非常简单的WebMethod。但无论我尝试什么，它都无法正常工作。我们的想法是，当您将页面滚动到底部时，它会调用Web方法，但是ajax调用总是会失败。

代码背后：

Imports System.Web.Script.Services
Imports System.Web.Services

Public Class deafult
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    <System.Web.Services.WebMethod, ScriptMethod(ResponseFormat:=ResponseFormat.Json)>
    Public Shared Function Gettime() As String
        Return Now.ToShortDateString
    End Function
End Class

设计师代码：

    <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="deafult.aspx.vb" Inherits="test2.deafult" %>

<!DOCTYPE html>

<html>
<head runat="server">
    <title>testing</title>
</head>
<body>
    <form id="form1" runat="server">
    <div style="height:750px; background: red">
    <br /><br />

    </div>
    </form>

    <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
    <script type="text/javascript">

    $(window).scroll(function () {
        if ($(window).scrollTop() == $(document).height() - $(window).height()) {
            GetRecords();
        }
    });
    function GetRecords() {


        $.ajax({
            type: "POST",
            url: "default.aspx/Getime",
            data: "{}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: OnSuccess,
            failure: function (response) {
                alert(response.d);
            },
            error: function (response) {
                alert('failed');
            }
        });
    }
    function OnSuccess(response) {
        alert('done');

    }
</script>
</body>
</html>

Web配置：
