C # ASP.NET call functions from JavaScript

I have a small working application for ASP.NET and C # and I would like to add Javascript to it.

I know that, for example, I can use the Confirm button and then do something with yes or no.

What I would like to do is call some of the functions that I have in the code, depending on the response to the confirmation button.

How should I do it? Many thanks!

Simple

Put a hidden div on your aspx page that contains the button triggers for your methods:

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

In your javascript, in terms of verifying your code, simply do:

__doPostBack('TriggerMethod1', '');

And in your code, process this button to call Method1.
