                                  //$('#mainMenu').show(); <-- this does not give desired result
                }
                else
                {
                    if(data.message=="user not verified")
                    {
                        //display verification page
                    }   
                    if(data.message=="no user exist with this usname")
                    {
                        //set focus to username
                        $("#username").focus();
                    }   
                }   
        }, "json");
}

and the page structure is like this

<div data-role="page" id="login">
    // other page content
            <div id="divrightButton">

            <!-- calling loginSubmit which calls loginPostData-->   
            <a class="bluebutton" href="#" onclick="loginSubmit(); return false;">Login</a>

            </div>
        </form>
</div>

<!--main page-->
<div data-role="page" id="mainMenu">

     Main menu
</div>

HOW TO SHOW MAIN MENU WHEN THERE IS SUCCESS,
the entire code of html is in single file in different div’s

Answer 1

use this code to redirect/display the particular div element

$.mobile.changePage("#mainMenu",{allowSamePageTransition: true });

and also download following css file, its a must for transitioning between pages/div elements

jquery.mobile.transitions.css
