问候，
无论我做什么，我都无法让我的 jquery ajax 代码从 ashx 处理程序页面获取除 null 之外的响应。
这是我的 hmt 页面:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>:: ashx tester ::</title>
<link rel="stylesheet" href="js/jqueryui/1.8.6/themes/sunny/jquery-ui.css"
type="text/css" media="all" />
<script type="text/javascript" src="js/jquery/1.4.3/jquery.min.js"></script>
<script type="text/javascript" src="js/jqueryui/1.8.6/jquery-ui.min.js"></script>
<script type="text/javascript" src="js/json2/0.0.0/json2.js"></script>
<script type="text/javascript">
$(function () {
$('#btnSubmit').click(
function () {
DoIt();
}
);
});
function DoIt() {
$('#btnSubmit').hide();
$.ajax({
type: "POST",
url: "http://localhost:49424/Handler1.ashx",
data: {
firstName: 'Bob',
lastName: 'Mahoney'
},
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (response) {
alert('success: ' + response);
$('#btnSubmit').show();
},
error: function (response) {
alert('error: ' + response);
$('#btnSubmit').show();
}
});
}
</script>
</head>
<body>
<input id="btnSubmit" type="button" value="Submit" />
</body>
</html>
这是我的 ashx 页面:
Imports System.Web
Imports System.Web.Services
Imports System.Collections.Generic
Imports System.Linq
Imports System.Data
Imports System.Configuration.ConfigurationManager
Imports System.Web.Services.Protocols
Imports System.Web.Script.Serialization
Public Class Handler1
Implements System.Web.IHttpHandler
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim j As New System.Web.Script.Serialization.JavaScriptSerializer
Dim s As String
s = j.Serialize(Now)
context.Response.ContentType = "application/json"
context.Response.Write(s)
End Sub
ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
Get
Return False
End Get
End Property
End Class
有什么线索吗？
谢谢!

最佳答案
尝试一下 url: "/Handler1.ashx",
而不是
url: "http://localhost:49424/Handler1.ashx",
