如何在c＃codebehind中调用具有返回值的Javascript函数 [英] How to call a Javascript function having return value in c# codebehind

问题描述

我有一个页面，我需要确认是否显示更新的网格

I am having a page where i need to confirm whether to show updated grid or not

我正在使用<调用javascript函数/ p>

I am calling a javascript function using

ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "confirm('Are u sure');", true);

我想知道的是如何在C＃代码中获取confirm的返回值。

What I want to know is how to get the return value of confirm in C# code behind.

推荐答案

而不是这个

ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "confirm('Are u sure');", true);

使用此

ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "ConfirmUser('Are u sure');", true);

<script type='javascript'>
 function ConfirmUser(msg)
 {
  if(confirm(msg))
    __doPostBack('','');
 }
<script>
