Banner Picker in jQuery I would like to know if my current jQuery code could be improved? If yes, can you give me improvements?

$(document).ready(function($)
{
    $("#bannerPickerToggleIcon").click(function(e)
    {
        e.preventDefault();
        $("#bannerPicker").slideToggle();
        $("this").css({"display": "block"});
        $("#bannerPickerToggleIcon").toggleClass("active");
    });
    $("#bannerPicker span").click(function()
    {
        var bannerid = $(this).attr("id");
        $.cookie('bannerimg', bannerid,
        {
            expires: 365,
            path: '/'
        });
        $("body").removeClass().addClass(bannerid);
    });
    if (($.cookie('bannerimg') !== null))
    {
        $("body").addClass($.cookie('bannerimg'));
    }
    else
    {
        $("body").addClass("bannerDefaultImage");
    }
});
&lt;/script&gt;


The code allows to open a selection of banners allowing the user to select a banner from the selection. Once a user has selected a banner, this one is saved via a cookie to save the selection. I created a cookie js file. It's the default cookie file from jQuery. Currently the code works, but I would like to know if it could be improved.
You don't need to wrap your JQuery code in $(document).ready(function() { ... }). See this Stackoverflow question here for more details on that.

The general style for brackets is that the open bracket is on the same line of the declaration, like this below example.

function f() {
    ...
}


Other than that, there's not much else here that I can see that's glaringly wrong, or in need of review. If there's anything else that you want me to cover, just ask, and I'll see what I can do.
