通过javascript访问后台代码的功能. [英] Access function of codebehind through javascript.

问题描述

我已将Java脚本的函数声明为

Hi,

I have declare a function of java script as

<script type="text/javascript">
        function Create_New_control()
        {
            PageMethod.Create_New_Instance();
        }
        </script>

我想在文本框模糊时调用它，所以我在.cs文件中将其称为
txt_comments.Attributes ["onblur"] ="Create_New_control()";

我在cs文件中的功能定义为

I want call this on blur of textbox so i calls it in .cs file as
txt_comments.Attributes["onblur"] = "Create_New_control()";

And my Function in cs file is defined as

[System.Web.Services.WebMethod]
   public static void Create_New_Instance()
   {
       // Statements
   }

但是"Microsoft JScript运行时错误:"PageMethod"未定义"此错误在运行时发生.


因此，我现在需要做些什么来解决此错误.


请给我建议.

在此先感谢.

But "Microsoft JScript runtime error: ''PageMethod'' is undefined" this error occurs at runtime.


So how i need to do now to resolve this error.


Please suggest me.

Thanks in advance.

推荐答案

其PageMethods不是PageMethod.另外，您是否尝试过在ScriptManager中进行设置? EnablePageMethods="true"?

Its PageMethods not PageMethod. Also, have you tried setting this in your ScriptManager? EnablePageMethods="true"?

您是否在ScriptManager中启用了页面方法?启用它，然后重试..

Did you enable the pagemethod in the ScriptManager? Enable it and then try again..

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