在我的母版页中，我

<head>
<script type="text/javascript">
$(document).ready(function() {
$("#result").click(function() {
$.ajax({type: "POST",url: "ws.aspx/HelloWorld",data: "{}",contentType: "application/json; charset=utf-8",dataType: "json",success: function(msg) {
$("#result").text(msg.d);
}
});
});
</script>
</head>
<body>
<form>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server" />
<div name="result" id="result">long clicky text</div>
</form>
</body>

的 ws.aspx 页面中没有母版页引用，并且是空的，除了

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="ws.aspx.vb" Inherits="CRTWebApp.ws" %>

<html>
<head>
</head>
<body>
</body>

它在 firebug 中是这样声明的

<System.Web.Services.WebService()> _ 
Partial Public Class ws
 Inherits System.Web.UI.Page

<System.Web.Services.WebMethod()> _ 
<System.Web.Script.Services.ScriptMethod(ResponseFormat:=Script.Services.ResponseFormat.Json)> _
        Public Shared Function HelloWorld() As String
            Return "hello world"
        End Function
    End Class

在我的 ws.aspx.vb 文件中，如果我单击“长点击文本”， “这就是发生的情况

POST HelloWorld 404 Object Not Found

ws.aspx 位于同一个文件夹中，它吐出的 url 是正确的，我可以冲浪到该页面（尽管它是空的..）

这是请求和响应

原文

in my master page, i have

<head>
<script type="text/javascript">
$(document).ready(function() {
$("#result").click(function() {
$.ajax({type: "POST",url: "ws.aspx/HelloWorld",data: "{}",contentType: "application/json; charset=utf-8",dataType: "json",success: function(msg) {
$("#result").text(msg.d);
}
});
});
</script>
</head>
<body>
<form>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server" />
<div name="result" id="result">long clicky text</div>
</form>
</body>

in my ws.aspx page, which has no master page references, and is empty except for

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="ws.aspx.vb" Inherits="CRTWebApp.ws" %>

<html>
<head>
</head>
<body>
</body>

in my ws.aspx.vb file it is declared like this

<System.Web.Services.WebService()> _ 
Partial Public Class ws
 Inherits System.Web.UI.Page

<System.Web.Services.WebMethod()> _ 
<System.Web.Script.Services.ScriptMethod(ResponseFormat:=Script.Services.ResponseFormat.Json)> _
        Public Shared Function HelloWorld() As String
            Return "hello world"
        End Function
    End Class

in firebug, if i click on "long clicky text" this is what happens

POST HelloWorld 404 Object Not Found

ws.aspx is in the same folder, the url it spits out is the correct one, i can surf to that page (though it is empty..)

here is request and response
