Question

我正在将wcf服务用于java脚本Web应用程序。我通过使用类库项目创建了wcf服务，然后我添加了引用java脚本客户端项目。我想通过使用Web应用程序将新记录插入数据库，但问题是当我点击提交按钮时，它会在谷歌控制台窗口中显示以下错误..

**Uncaught ReferenceError: tempuri is not defined
at CallStudentDataService (Default.aspx:19)
at HTMLInputElement.onclick (Default.aspx:93)**

这是界面。

    [OperationContract]
    string InsertStudentRecord(string Name, string Email, string Address, string Mobile);

这是实施。

 public string InsertStudentRecord(string Name, string Email, string Address, string Mobile)
        {
            SqlConnection con = new SqlConnection(@"Data Source=.;Initial Catalog=3TierInWindowsApplication;Integrated Security=True");
            SqlCommand cmd = new SqlCommand("AddNewStudent", con);
            cmd.CommandType = CommandType.StoredProcedure;

            cmd.Parameters.AddWithValue("@Name", Name);
            cmd.Parameters.AddWithValue("@Address", Address);
            cmd.Parameters.AddWithValue("@EmailId", Email);
            cmd.Parameters.AddWithValue("@Mobile", Mobile);

            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
            return "Success";
        }

这是.svc代码。

<%@ ServiceHost Language="C#" Debug="true" Service="StudentServiceWcf.StudentService"%>

这是HTML CODE。

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

            var Email = document.getElementById("TxtEmail").value;

以下是我为解决此错误所做的更改。

我将.svc文件代码更改为＆lt;％@ ServiceHost Language =＆＃34; C＃＆＃34;调试=＆＃34;真＆＃34;服务=＆＃34; StudentServiceWcf.StudentService＆＃34; 厂=＆＃34; System.ServiceModel.Activation.WebScriptServiceHostFactory＆＃34; ％GT;
要找到正确的界面路径，只需在localhost路径中添加带符号（/）的jsdebug，如http://localhost:51142/StudentService.svc/jsdebug

将Wcf服务应用到Java脚本应用程序中
