  • Model: The model deals with the raw data and database interaction and will contain functions like adding records to a database or selecting specific database records. In CI the model component is not required and can be included in the controller.
  • View: The view deals with displaying the data and interface controls to the user with.In CI the view could be a web page, rss feed, ajax data or any other "page".
  • Controller: The controller acts as the in between of view and model and, as the name suggests,it controls what is sent to the view from the model. In CI, the controller is also the place to load libraries and helpers.

Enhancing Webpage Security with jQuery: Preventing Right-Click and Hotkey Access

In jquery there is differect types of events in which we have to block 'F12','Ctrl+Shift+I' and right click i.e.'keycode 123' for whole document. All keycode and button  opens the Inspect Element screen in the browser. Adding a keydown event than only does return false for 123 will block the Inspect Element screen.

For preventing Right click Context menu:
 
$(document).on("contextmenu", function (e) {        
    e.preventDefault();
});

For preventing 'F12' and 'Ctrl+Shift+I' button click:
 
$(document).keydown(function (event) {
    if (event.keyCode == 123) // Prevent F12
    { 
        return false;
    } 
    else if(event.ctrlKey && event.shiftKey && event.keyCode == 73)
    // Prevent Ctrl+Shift+I
    {         
        return false;
    }
});
