Aplicar clases en Javascript

Hola, tengo el siguiente codigo que corresponde a 3 pestañas hechas con spry:

...

<link href="../SpryAssets/SpryValidationTextField.css" rel="stylesheet" type="text/css" />
</head>

<body>

<div id="fichas" class="TabbedPanels">
<ul id="contfichas" class="TabbedPanelsTabGroup">
<li class="TabbedPanelsTab" tabindex="0">Dominios</li>
<li class="TabbedPanelsTab" tabindex="1">Clientes</li>
<li class="TabbedPanelsTab" tabindex="2">Correos</li>
</ul>

<div class="TabbedPanelsContentGroup">

<!-- ******************************************** -->
<!-- COMIENZO DE LA PESTAÑA 1 ->
<!-- ******************************************** -->

<div id="contenido1" class="TabbedPanelsContent">

...


Me gustaria saber como puedo aplicarle al objeto <li> con id=1 la clase que define que la pestaña esta seleccionada desde esta funcion javascript:


function VerContenido2()
{

for (var i=1; i<4; i++)
{
if(i!=2)
{
document.getElementById('contenido'+i).style.displ ay = 'none';
}else{
document.getElementById('contenido'+i).style.displ ay = 'block';
}
}
}

Con este funcion he conseguido que, llamandola en el evento onclick de un link, se me vea el contenido de la pestaña con id=1, pero ahora tengo que conseguir que esa pestaña se muestre como seleccionada y las otras dos como no seleccionadas.

Este es el css donde estan definidas las clases:

* interaction with other floated elements on the page that may be used
* for layout.
