I was using bootstrap components to make responsive size adjustable web application but the problem I am getting is all the component calls client side java script as far as I understood. 

 

it can call Java script Function written in the same page or it redirects to another page.

 

But can I call a custom function written in C++ in my web application as I can call it within the web application.

If I understand correctly, you basically want to call a function in your application, written in C++, from your page (i.e. an event from a component on that page). Is that correct?

 

If that's correct there are several ways to accomplish that. I don't have a C++ Builder demo ready, but there is one written in Delphi which should be quite simple for you to understand how it works. Please have a look:

Yes sir,

 

That's correct. But I want to call it from HTML template page.

 

like calling from menu item.

 

if menu item selected [student list] i need to call loadstudentlist function. currently I am redirecting to another page and showing student list.

Hi, you can call from html template in your menu list, something like this:

 

Code:

 

<li><a href="#" onclick="return ajaxCall('YOUR_DELPHI_FUNCTION', 'parametermenulist=student_list');"><i class="fas fa-map-pin"></i><p>student_menu1</p></a></li>

Ilustre Jose Nilton,

 

Estou implementado o callback mas a expressão ajaxCall não está a ser identificado. É necessário declarar no ficheiro JQuery ou no delphi?

 

A mensagem de erro no console do brownser é a seguinte: "Uncaught ReferenceError: ajaxcall is not defined"

 

Ajude-me por favor...
