The problem with your code is you are trying to retrieve it onclick. That's the wrong logic. The correct logic is: when the page loads, retrieve it. When the li is clicked, store it. You also have a problem when using find("active"), you need to use the class character . otherwise it will search for elements with the tag name active not the class.

$(document).ready(function () {
    $("li").click(function () {
        var id = $(this).attr("id");

        $('#' + id).siblings().find(".active").removeClass("active");
            //                       ^ you forgot this
        $('#' + id).addClass("active");
        localStorage.setItem("selectedolditem", id);
    });

    var selectedolditem = localStorage.getItem('selectedolditem');

    if (selectedolditem != null) {
        $('#' + selectedolditem).siblings().find(".active").removeClass("active");
        //                                        ^ you forgot this
        $('#' + selectedolditem).addClass("active");
    }
});

Try following.

$('li').each(function(){
    if(window.location.href.indexOf($(this).find('a:first').attr('href'))>-1)
    {
    $(this).addClass('active').siblings().removeClass('active');
    }
});

Try following.

$(document).ready(function() {
            $('.active').removeClass('active');
            var currurl = window.location.pathname;
            var val=$('li:has(a[href="'+currurl+'"])').addClass('active');
        });
