    $lis.click(function () {
        SwichSkin(this.id);
        SetSkinCooke(this.id);
    });

    setSkinFromCookie();
});

function SwichSkin(skinName) {
    $("#" + skinName).addClass("selected")
        .siblings().removeClass("selected");
    
    var cssfilePath = "styles/skin/" + skinName + ".css";
    $("#cssfile").attr("href", cssfilePath);
}

function SetSkinCooke(skinName) {
    $.cookie("MyCssSkin", skinName, { path: '/', expires: 1 });
}

function setSkinFromCookie() {
    var skinCookie = $.cookie("MyCssSkin");
    if (skinCookie) {
        SwichSkin(skinCookie);
        SetSkinCooke(skinCookie); 
    }
}
