问候,
我到处寻找,我看到的每个答案都告诉我将以下内容放在我的web.config中:
<system.web>
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
</system.web>
所以我已经做到了,我仍然得到错误.
这是我网页上的脚本:
<script>
$(function () {
$('#btn').click(
function () {
CallHome();
}
);
});
function CallHome() {
$.ajax({
type: "POST",
url: "HelloWorld.asmx/HelloWorld",
dataType: "xml",
data: "{}",
contentType: "xml",
success: function(data) {
alert(data);
}
});
}
</script>
WebService.vb是:
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports System.Web.Script.Services
<System.Web.Script.Services.ScriptService()> _
<System.Web.Services.WebService(Namespace:="http://tempuri.org/")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ToolboxItem(False)> _
Public Class HelloWorld
Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function HelloWorld() As String
Return "Hello World" …问候,
无论我做什么,我都无法从ashx处理程序页面获取我的jquery ajax代码以获得除null之外的响应.
这是我的hmt页面:
