change css class on mouse over

Hi im trying to make my navigation bar do the css focus effect on mouseover so it will not change until another menu item has the mouseover. Im trying to do it using Jquery.

Here is my code(I did import the jquery script btw and my css class):

    <div id="topNav">
<a href="contact.html"class="topNavNormal"><div id="topNav4" class="topNavNormal">Contact Us</div></a>
<a href="about.html" class="topNavNormal"><div id="topNav3" class="topNavNormal">About Us</div></a>
<a href="services.html" class="topNavNormal"><div id="topNav2" class="topNavNormal">Services</div></a>
<a href="index.html" class="topNavActive"><div id="topNav1" class="topNavActive" style="border-left: 3px solid #c0c0c0;">Home</div></a>
<script type="text/javascript">
$(document).ready(function(){
$('#topNav1').mouseover(function(){
    $('#topNav1').removeClass().addClass('topNavActive'),
    $('#topNav2').removeClass().addClass('topNavNormal'),
    $('#topNav3').removeClass().addClass('topNavNormal'),
    $('#topNav4').removeClass().addClass('topNavNormal'),
    });
}),
$('#topNav2').mouseover(function(){
    $('#topNav2').removeClass().addClass('topNavActive'),
    $('#topNav1').removeClass().addClass('topNavNormal'),
    $('#topNav3').removeClass().addClass('topNavNormal'),
    $('#topNav4').removeClass().addClass('topNavNormal'),
    });
}),
$('#topNav3').mouseover(function(){
    $('#topNav3').removeClass().addClass('topNavActive'),
    $('#topNav1').removeClass().addClass('topNavNormal'),
    $('#topNav2').removeClass().addClass('topNavNormal'),
    $('#topNav4').removeClass().addClass('topNavNormal'),
    });
}),
$('#topNav4').mouseover(function(){
    $('#topNav4').removeClass().addClass('topNavActive'),
    $('#topNav1').removeClass().addClass('topNavNormal'),
    $('#topNav3').removeClass().addClass('topNavNormal'),
    $('#topNav2').removeClass().addClass('topNavNormal'),
});
});
</script>
</div>

Also Here is my Css Classes:

<style type="text/css">
#topNav1
{
text-align: center;
font-size: 18px;
float: right;
width: 50px;
height: 64px;
}
#topNav2
{
text-align: center;
font-size: 18px;
float: right;
width: 70px;
height: 64px;
}
#topNav3
{
text-align: center;
font-size: 18px;
float: right;
width: 90px;
height: 64px;
}
#topNav4
{
text-align: center;
font-size: 18px;
float: right;
width: 90px;
height: 64px;
}
#topNav1, #topNav2,  #topNav3{
border-right: 1px solid #c0c0c0;
}
#topNav4{
border-right: 3px solid #c0c0c0;
}
a .topNavNormal{
line-height: 54px;
color: #42647F;
}
.topNavNormal{
background-color: #B0E0E6;
}
a .topNavActive{
line-height: 54px;
color: #00EEEE;
background-color: #5F9EA0;
}
</style>

If you don't care about IE6 - just use :hover like James suggeted. Otherwise simplify your code:

    $(document).ready(function () {
        $('#topNav a').hover(function () {
            $(this).addClass('topNavActive');
        }, function () {
            $(this).removeClass('topNavActive');
        });
    });

if you want to immitate :focus (but with mouseover):

    $(document).ready(function () {
        $('#topNav a').hover(function () {
            $(this).siblings().removeClass('topNavActive');
            $(this).addClass('topNavActive');
        }
    });

is it what you need?

The best practice is to solve it with pure CSS (without any jQuery at all). here's a quick example:

<style type="text/css">    
    .navItem { 
        background: yellow;
     }
    .navItem:hover { 
        background: blue;
    }
</style>

.topNavNormal{
    background-color: #B0E0E6;
}

a .topNavNormal{
    line-height: 54px;
    color: #42647F;
}

if you aren't using these in different places i'd merge them and then you can just

a .topNavActive{    
    line-height: 54px;
    color: #00EEEE;
    background-color: #5F9EA0;    
}

and a simple javascript like:

$('topNavNormal').mouseover(function(){
    $('topNavNormal').removeClass('topNavActive');
    $(this).addClass('topNavNormal');
});

try something like this.

    $('.topnav_class').over(function(){
        // delete all the classes of hover
        $(.topnav_class).removeClass('hover');
        // add the hover class just to this node
        $(this).addClass('hover);
    }, function(){
        $(this).addClass('hover');
    });

You have to play with $(this) more so you can do your jQuery a little more DRY (Do not repeat yourself)

This Works for me

$(".panel").hover(function () {
    $(this).addClass('panel-info');
    $(this).removeClass('panel-warning');
}, function () {
    $(this).removeClass('panel-info');
    $(this).addClass('panel-warning');
});

This works for me. If you want to do something excited with bootstrap. Try this:

 $(".small").hover(function () {
        $(this).addClass('lead');
        $(this).removeClass('small');
    }, function () {
        $(this).removeClass('lead');
        $(this).addClass('small');
    });
