I have a small working application in ASP.NET and C#, and I would like to add some JavaScript code to it.

I know that, for example, I can use the Confirm button and then do something on Yes or No.

I would like to call some of the functions I have in the code-behind, depending on the answer to the Confirm button.

How do I go about this?

Simple.

Put a hidden div on your .aspx page that contains button triggers to your methods:

<div style="display: none">
     <asp:Button ID="TriggerMethod1" runat="server" />
</div>

In your JavaScript code, in the confirm part of your code, simply do:

__doPostBack('TriggerMethod1', '');

And in your code-behind, handle up that button click to call Method1.

I would create an ASHX handler file and post back to the hander using jQuery ajax methods.

See an article on this here:

To call a server-side method on a client-side event you need to do the following:

1. Create the server-side method:

   void DoSomething(...) { ... }
   

2. Implement the System.Web.UI.IPostBackEventHandler.RaisePostBackEvent which take one string argument (you can assign the name to the value of this argument).:

   public void RaisePostBackEvent(string eventArgument)
   {
           DoSomething(...);
   }
   

3. Write a script to trigger a post back:

   function TriggerPostBack(control, arg){
       __doPostBack(control, arg);
   }
   

4. Call the PostBack trigger function when needed:

    <a .... onclick="TriggerPostBack('control', 'arg')" .. />
