问题描述

我们现有的asp net应用程序也包含web服务。此服务标有ScriptService属性。
我们想要的是允许来自"第三方"的jscript的调用。网页。我尝试在名为WebApp2的新Web应用程序中构建asp.net页面，并从中引用此类服务，例如

< form id =" form1" RUNAT = QUOT;服务器"> 
< asp：ScriptManager runat =" server"> 
<服务> 
< asp：ServiceReference Path =" http：//< serverName> /WebApp1/services/TestService.asmx" /> 
< / Services>来自jscript的
< / asp：ScriptManager>

我需要调用它

< script type =" text / javascript"> 
函数updateAlarm（）{
 var client = new TestPortal.TestService（）; 
 var res = client.TestMethod（）; 
} 
< / script>

当jscript运行的服务和页面位于同一个Web应用程序时，此方法有效。但是，情况并非如此，并且不起作用。我需要做些什么才能让它运转？

Hi,

we have existing asp net application containing also web service. This service is marked with ScriptService attribute.
What we want is to allow calls from jscript from "3rd party" web pages. I tried to build-up asp.net page in new web application called WebApp2 and reference such service from it like

    <form id="form1" runat="server">
    <asp:ScriptManager runat="server">
        <Services >
            <asp:ServiceReference Path="http://<serverName>/WebApp1/services/TestService.asmx"/>
        </Services>
    </asp:ScriptManager>

from jscript i need to call it

    <script type="text/javascript">
        function updateAlarm() {
            var client = new TestPortal.TestService();
            var res = client.TestMethod();
        }
    </script>

This works when service and page where the jscript runs from are on same web app. However, this is not the case and it doesn't work. What i need to do in order to get it running?

thanks for any help
