[Solved] Declaring variables jQuery

You can use for for looping through array elements:

var url = ["aaa", "bbb", "ccc"]

for (var i = 0; i < url.length; i++)
{
    if (window.location.href.indexOf(url[i]) > -1)
    {
        $("#wrap").css({display: 'block'});
        $("#nav").css({display: 'block'});
        break;
    }
}
