JavaScript confirm from code behind C#
提问by Null Pointer
I have a button on my aspx page. I want to use javascript confirm before continuing execution when clicking on that button. I can do it easily if i am writing javascript in aspx page itself . But my problem is each time the confirm message may be different. I need to check various condition to generate appropriate confirm message.
我的 aspx 页面上有一个按钮。单击该按钮时，我想在继续执行之前使用 javascript 确认。如果我在 aspx 页面本身中编写 javascript，我可以轻松完成。但我的问题是每次确认消息都可能不同。我需要检查各种条件以生成适当的确认消息。
Can I call confirm in my code behind, so that I can construct confirm message from there?
我可以在后面的代码中调用确认，以便我可以从那里构造确认消息吗？
What I'm trying is:
我正在尝试的是：
protected void Button1_Click(object sender, EventArgs e)
{
//just the algorithm given here
string message=constructMessage(); \ its just a function to construct the confirm message
if(confirm(message)) // i know i cant use javascript in code behind direct. How can i do this
{
//do something
}
else
{
// do nothing
}
}

protected void Button1_Click(object sender, EventArgs e)
{
string message=
"if(confirm("+message+"))
{
//do something
}
else
{
// do nothing
}";
this.ClientScriptManager.RegisterStartupScript(typeof(this.Page), "warning", message, true);
//Prints out your client script with <script> tags
}
For further reference on ClientScriptManager
