从脚本函数调用服务器方法 [英] Calling a server method from script function

问题描述

我从java脚本函数调用服务器方法，但它正在调用。那它有什么问题。请告诉我。



这是脚本：

Hi,
I am calling a server method from a java script function but it is getting invoke. So what is the problem it is having. Please advise me.

This is the script:

<script type="text/javascript" language="javascript">
        function servermethod() {
            var name = $get("txtname").value;
            PageMethods.CallingserverMethod(name);

            alert(name);
        }

Code Behind：

Code Behind:

[WebMethod]
      public static string CallingserverMethod(string name)
      {

          return "Hi" + name + Environment.NewLine + "This is an example";
      }

推荐答案

get（txtname）。value;
PageMethods.CallingserverMethod（name）;

alert（姓名）;
}

get("txtname").value; PageMethods.CallingserverMethod(name); alert(name); }

Code Behind：

Code Behind:

[WebMethod]
      public static string CallingserverMethod(string name)
      {

          return "Hi" + name + Environment.NewLine + "This is an example";
      }

.cs file
[ScriptMethod, WebMethod]

   public static string CallingserverMethod(string name)
   {
       return "Hi" + name + Environment.NewLine + "This is an example";
   }

.aspx file

<script type="text/javascript">
      function servermethod()
      {
          PageMethods.CallingserverMethod(onSuccess, onFailure);
      }

  function onSuccess(result) {
          alert(result);
      }


      function onFailure(error) {
          alert(error);
      } 

</script>

然后点击此处调用此servermethod（） .aspx代码中的按钮。

Then call this servermethod() on click of button in your .aspx code.
