Hello
How to call a class file function in java script..I have a class file let class1.cs in which i define a function let log_record()....i wanna call this function in my java script function how can i do this please help .....

My complete Class file class1.cs is.....

public class age_calculator
{
    public age_calculator()
    {
        //
        // TODO: Add constructor logic here
        //
    }

public void log_info(out string browser, out string pagepath, out string pagename, out string ip, out string dt)
    {
        string pgepath = System.Web.HttpContext.Current.Request.Url.AbsolutePath;
        pagepath = System.Web.HttpContext.Current.Request.Url.ToString();
        System.IO.FileInfo oinfo = new System.IO.FileInfo(pgepath);
        pagename = oinfo.Name;
        string visitorIP = HttpContext.Current.Request.UserHostAddress.ToString();
        ip = GetIP();
        dt = Convert.ToString(DateTime.Now);
        //string browser;
        browser = HttpContext.Current.Request.Browser.Browser.ToString();
        browser = browser + "-" + HttpContext.Current.Request.Browser.Version.ToString();

实际上我想打电话这个函数在我的经典asp页面上，但它不可能直接所以我想在java脚本中调用它然后在我的代码中调用javascript函数...如果你有任何其他方式那么请建议我..

推荐答案

在aspx页面方法中调用类函数，然后通过javascript调用此方法。

见这里 ASP.NET - 如何从客户端JavaScript调用服务器端方法 [ ^ ]

Call your class function in an aspx page method then call this method via javascript.
See here ASP.NET – How to call a server-side method from client-side JavaScript[^]

请参阅：如何使用JavaScript排除ac＃方法（代码隐藏） [ ^ ]



问候..

See this: How to excecute a c# Method (Code-Behind) with JavaScript[^]

从服务器端调用函数用一个属性作为f来装饰你的函数ollow。

For calling a function from server side decorate your function with a Attribute which is as follow.

[WebMethod]
    public static bool IsUserAvailable(string val)
    {
        if (val == "daljeet")
        {
            return true;
        }
        else
        {
            return false;
        }
    }

现在注册你的函数添加一个脚本管理器控件到你的页面使用EnablePageMethods属性集为真。

Now for registering your function add a script manager control to your page with EnablePageMethods property set to true.

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
    </asp:ScriptManager>

      <asp:Button ID="btnForPass" runat="server" Text="Click Here"  OnClientClick="CallJavascript();"/>

      </form>

现在按钮点击我正在调用一个调用函数的javascript函数服务器端。

now on the button click i am calling a javascript function which is calling the function from server side.

<script language="javascript" type="text/javascript">

       function CallJavascript() {
           PageMethods.IsUserAvailable(username, OnSucceeded);
       }
       function OnSucceeded(result, userContext, methodName) {
           if (methodName == "IsUserAvailable") {
               if (result == true) {
                   alert("Success");

               }
               else {
                   alert("Failed");

               }
           }
       }
     </script>
