Dav*_*ave 10 asp.net ajax jquery web-services

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>

当您从浏览器访问该服务时，您是否收到“Hello World”？

另外，您是否在网址中缺少尾随“/”？
