创建新的asmx页面时出现问题 [英] Problem while create a new asmx page

问题描述

大家好



我正在创建一个asmx网络服务。

在visual studio 2012中项目名称我右键单击并添加Web服务名称 UserDetails.asmx



现在我正在尝试在js文件中使用Web服务。像这样

Hi all

I am creating an asmx web service.
In visual studio 2012 on the project name I right clicked and added an web service name UserDetails.asmx

Now I am trying to use the web service in the js file. like this

$.ajax({
       type: "POST",
       url: "UserDetails.asmx/HelloWorld",
       contentType: "application/json; charset=utf-8",
       dataType: "json",
       success: function (data) {
          alert('success');
       },
       error: function () {
           alert("Error");
       }
   });

显示错误 POST http://192.168.9.185/GPS/UserDetails.asmx/HelloWorld 500（内部服务器错误）



我的代码中是否有任何错误或者我遗漏了某些内容以致显示错误。

我的Asmx页面

Its showing error that POST http://192.168.9.185/GPS/UserDetails.asmx/HelloWorld 500 (Internal Server Error)

Is there any fault in my code or I am missing something so that its showing error.
My Asmx Page

推荐答案

.ajax（{
type： POST，
url： UserDetails.asmx / HelloWorld ，
contentType： application / json; charset = utf-8，
dataType： json，
成功： function （data）{
alert（' success'）;
}，
错误： function （）{
alert（ 错误）;
}
}）;

.ajax({ type: "POST", url: "UserDetails.asmx/HelloWorld", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { alert('success'); }, error: function () { alert("Error"); } });

显示错误 POST http://192.168.9.185/GPS/UserDetails.asmx/HelloWorld 500（内部服务器错误）

取消注释 [System.Web.Script.Services.ScriptService]



这样你就可以在js文件中使用这个web方法

Just uncomment the [System.Web.Script.Services.ScriptService]

So that you can use this web method in the js file
