Navigate to Page

Example:

// var p_app_page_id = apex.item('APP_PAGE_ID').getValue() ; ;
// var p_parameter   = apex.item('P'+ p_app_page_id + '_ID').getValue() ;
// var p_url         = "f?p=&APP_ID.:1:&SESSION.::&DEBUG.:1:P1_ID:" + p_parameter + ":" ;   
//
apex.message.showPageSuccess( "Redirecting, please wait ...." );
//
var p_url         = "f?p=&APP_ID.:1:&SESSION.::&DEBUG.:1:::" ;   
fn_page_navigation( p_url ,'' ); 

Code

// Pass parameter to apex.message.showPageSuccess function
// Set a timeout in milliseconds and the hide-message 3 second after it is displayed.
function fn_show_notification( Msg, timeOut){  
        apex.message.showPageSuccess( Msg );

        //
        $('#t_Alert_Success').attr('style','background-color: #000000;');
};

// Dismiss Notifications

         success: function (data) {

      },
         error: function( jqXHR, textStatus, errorThrown ) {
         // handle error
    }
   });
   };

// Page Navigation No Message, returns checksum for URL
   function fn_page_navigation_no_message ( p_url ) {
