如何从JavaScript调用一个C＃功能？ [英] How to call a C# function from javascript?

问题描述

我要打电话 CsharpFunction code从JavaScript后面。我想下面的code。问题是，条件是否为真或假，编译器会调用 CsharpFunction 反正！我该如何控制？

I want to call CsharpFunction code behind from JavaScript. I tried the code below. The problem is that whether the condition is True or False, the compiler will call CsharpFunction anyway! How I can control that?

JavaScript的code：

JavaScript code:

if (Javascriptcondition > 0) {
   <%CsharpFunction();%>
}

C＃code背后：

C# code behind:

protected void CsharpFunction()
{
  // Notification.show();
}

感谢您的帮助！

您可以使用Web方法和Ajax

You Can use Web Method and Ajax

   <script type="text/javascript">             //Default.aspx
       function DeleteKartItems() {     
                 $.ajax({
                 type: "POST",
                 url: 'Default.aspx/DeleteItem',
                 data: "",
                 contentType: "application/json; charset=utf-8",
                 dataType: "json",
                 success: function (msg) {
                     $("#divResult").html("success");
                 },
                 error: function (e) {
                     $("#divResult").html("Something Wrong.");
                 }
             });
         }

  [WebMethod]                                 //Default.aspx.cs
  public static void DeleteItem()
  {
     //Your Logic
  }
