Something like:

<div data-uri="_core/home.php" class="meniu-item">Home</div>
<div data-uri="_core/after-login.php" class="meniu-item">Contact</div>

With the jQuery:

$("div.meniu-item").on("click", function()
{
    $('#content').load($(this).data("uri"));
    window.location.hash = $(this).text().toLowerCase();

    // Remove the class 'selected' from all navigation items first.
    $("div.meniu-item").removeClass("selected");

    // Then add it to the one we clicked.
    $(this).addClass("selected");

});
