如何从javascript函数将参数传递给c＃方法 [英] how to pass parameter to c# method from javascript function

问题描述

我有一些像这样的javascript函数 -

I have some javascript function like this-

function updateVaues(paramValues)
{
  document.getElemntById('<%= txtRequisitionNo.ClientID %>').value=paramValues[0];
 //to fill gridviewItem I am calling c# method from javascript as--
  <% fillGrid(paramValues[0]); %>

}

但是我收到paramValues不存在的错误



然后如何在c＃

But I am getting error that paramValues does not exist

Then how can I pass paramValues[0] to fillGrid() in c#

推荐答案

你不能这样做。试想一下：Javascript是在客户端执行的，而C＃代码是服务器端的代码。客户端和服务器端之间发生的任何事情都可能是呼叫。服务器端代码仅用于响应来自客户端的某些HTTP请求。特别是，您可以使用Ajax发送请求。请参阅：

http://en.wikipedia.org/wiki/Ajax_%28programming ％29 [ ^ ]。



使用Ajax发送HTTP请求的一种便捷方法是使用jQuery .ajax（）：

You cannot do it. Just think about it: Javascript is executed on client side, and C# code is one the server side. Whatever happens between client and server side could be anything but not "call". The server-side code only works in response to some HTTP request from the client side. In particular, you can use Ajax to send a request. Please see:
http://en.wikipedia.org/wiki/Ajax_%28programming%29[^].

One convenient way to send an HTTP request using Ajax is using jQuery .ajax():
